6712SR Refrigerated Sampler  
Section 1 Introduction  
The 6712SR Refrigerated Sampler is an integral part of Teledyne  
Isco’s comprehensive sampling system. The system includes the  
6712SR and 6712SR Refrigerated Samplers, the 6712 Compact  
Sampler, and the 6712 Standard Sampler.  
The 6712SR is ideally suited for permanent installation in a wide  
variety of indoor and outdoor environments. Constructed from  
durable, corrosion resistant materials, the 6712SR withstands  
the hostile environments of industrial and municipal monitoring  
sites. However, do not install in locations where the refrigerator’s  
lower compartment could become submerged.  
The 6712SR accepts a variety of sequential and composite bottle  
kits. Like all samplers in the 6712 series, it is compatible with a  
variety of Teledyne Isco instruments.

6712SR Refrigerated Sampler  
Section 1 Introduction  
The appendices are:  
• Appendix A, Menu Flowcharts  
• Appendix B, Material Safety Data Sheets  
• Appendix C, General Safety Procedures  
• Appendix D, Replacement Parts  
• Appendix E, Accessories List  
1.2 About 700 Series  
Modules  
The bay on the controller’s side accepts any of Teledyne Isco’s 700  
Series Modules. The 700 Series includes:  
• 701 pH Parameter Module for monitoring pH and  
temperature.  
• 710 Ultrasonic Module for monitoring a flow stream’s  
level and flow rate with an ultrasonic level sensor.  
• 720 Submerged Probe Module for monitoring a flow  
stream’s level and flow rate with a submerged probe.  
• 730 Bubbler Flow Module for monitoring a flow stream’s  
level and flow rate with a bubbler system.  
• 750 Area Velocity Module for monitoring a flow stream’s  
level, velocity, and flow rate.  
• 780 4-20mA Input Module for interfacing to  
non-Teledyne Isco devices with 4 to 20 milliampere  
output signals.  
The modules are optional accessories, and are not required for  
operation. However, the modules offer a number of advantages:  
they are an economical way to combine flow-rate or parameter  
monitoring with sampling, and you can program the samplers  
and modules as a single unit. Finally, the samplers store the  
readings in memory.  
1.3 SDI-12 Sondes  
As an option, the sampler accepts up to 16 parameters from up to  
ten sensors with SDI-12 addresses from 0 - 9 (refer to SDI-12  
Sonde Readings, page 1-10, for specific parameters).  
The data parameters used by the sensing device (sonde) and  
recording device (sampler) must match. Certain vendors’ sondes  
have enhanced commands that facilitate “plug and play” setup.  
These Teledyne Isco Ready sondes can tell the 6712SR what  
values they have, their order, and units of measure. Other sondes  
can be used, but require manual setup to identify proper data  
types for each data value reported.  
1.4 Memory to Store  
Monitoring Data  
The samplers contain enough memory to store five sampling pro-  
grams, sampling data, Teledyne Isco 700 Series Module readings,  
and SDI-12 parameter readings. You can view the readings on  
your sampler’s display.  
You can also retrieve the readings and reports so the information  
can be processed on a personal computer. Readings and reports  
may be collected with a computer running Teledyne Isco’s  
Flowlink™ software. Flowlink can download the information  
through a direct connection, a modem connection (when the

sampler is equipped with the optional dial-out modem), or from a  
581 Rapid Transfer Device (RTD). The RTD is a quick and simple  
way to transfer the data from the field to your computer. Reports  
are easily collected with Teledyne Isco’s Samplink software.  
1.5 Pump Requirements  
The pump requires a pump tube made specifically for the 6712  
and 6700 Series samplers. These pump tubes are easily recog-  
nized by their blue alignment collars. The 6712 pump tubing is  
the same as that for Teledyne Isco’s 6700 Series samplers, but  
different from Teledyne Isco’s earlier model samplers, such as the  
3700 Series. Other types of pump tubing will not work in  
the 6712SR. Refer to Replacing the Pump Tube on page 8-8.

6712SR Refrigerated Sampler  
Section 2 Installation/Preparation  
2.1 Preparing the Sampler The 6712SR is shipped to you with the controller mounted on the  
refrigerator and a distributor shaft extension installed. Use  
Figure 2-1 for reference when removing the controller. You must  
remove the controller when:  
• The internal desiccant needs recharging, the internal  
battery needs to be replaced or when the controller  
needs repair.  
You install a different bottle kit.  
Each bottle kit has its own extension so that the distributor arm  
is positioned at the right distance above the bottles. You must  
remove the controller to replace the extension.  
2.1.1 Installing the  
Distributor Shaft  
Extension  
1. Install the extension before mounting the controller on the  
refrigerator.  
2. Select the extension of the correct length for the bottle kit,  
and screw it on the distributor shaft. Secure it with the set  
screw. See Figure 2-1.  
BE SURE THE SET SCREW IS TIGHTENED INTO THE  
DISTRIBUTOR SHAFT’S KEY. YOU MAY HAVE TO  
LOOSEN THE EXTENSION SLIGHTLY AND ADJUST ITS  
POSITION.  
2.1.2 Mounting the  
Controller  
1. Install the four mounting rods into the bosses on the bot-  
tom of the case.  
2. Fit the mounting rods through the four holes drilled in the  
top of the refrigerator.  
3. Slip a washer on each rod and secure the controller by  
tightening the wing nuts.  
4. Install the distributor arm and discharge tube.  
5. Thread the stop arm into the hole in the side of the exten-  
sion. Be sure the stop arm is directly above the distributor  
arm.  
6. Connect the power cable to the controller.

2.1.3 Installing the  
Distributor Arm and  
Discharge Tube  
The distributor arm is adjustable so that you can position the  
discharge tube over the bottles of each kit. Each bottle kit also  
uses a discharge tube of a specific length. Table 2-1 lists the  
correct discharge tube lengths for each bottle kit. If you are using  
bulk tubing to cut your own tubes, cut the ends of the tube  
square, not at an angle, and cut the length accurately.  
The two-piece distributor arm has four positions, marked on the  
underside with the letters A, B, C, and D. Adjust the arm to the  
correct position for the bottle kit being used. Table 2-1 shows the  
correct position for each kit. Thread the discharge tube through  
Distributor Arm  
1
the spring and arm so that the tube protrudes from the arm /16  
1
to /8 inch. If too much tube protrudes from the arm it can catch  
on bottles and jam the distributor arm.  
Attach the arm to the distributor shaft extension. Secure the arm  
to the extension with the black plastic nut. Slide the free end of  
the discharge tube onto the bulkhead fitting. After installing the  
distributor arm and discharge tube, run the distributor to each  
bottle position to ensure proper installation.

6712SR Refrigerated Sampler  
Section 2 Installation/Preparation  
2.2 Installing Bottle Kits  
Teledyne Isco ships the refrigerator from the factory with the  
sample bottles in place. When using the sampler for the first  
time, you will only need to remove the bottle lids. When  
installing cleaned bottles or a new kit, keep these guidelines in  
mind:  
• Do not mix glass and plastic bottles together.  
• Install all bottles to insure that they remain in place.  
• Align the racks correctly. If the racks are misaligned, the  
sampler may miss the bottle mouth, or the sampler will  
deposit samples in the “wrong” bottle.  
Each time you change from one size bottle to another, you must  
adjust the length of the distributor arm, install a discharge tube  
of the correct length, and possibly install a different distributor  
shaft extension.  
Each time you install a bottle kit, check the program settings for  
the number of bottles and bottle volumes. Also rotate the dis-  
tributor arm to each bottle position to ensure the arm is correctly  
positioned over each bottle. Use the controller to move the arm.  
2.2.1 Installing Racks  
Install the bottle rack with bottles by sliding it into the cooling  
compartment until the rack drops over the two semicircular  
ramps which hold it in place (Figure 2-2).  
The five posts and two ramps which position the rack under the  
distributor arm are adjusted at the factory. When you change  
bottle kits, you may need to readjust the stops and ramps and  
install a different distributor arm extension. Figures 2-3 and 2-4  
show you how to install the bottle kits.  
Check the kit’s alignment by rotating the distributor arm. Do  
not rotate the distributor manually. Moving the arm man-  
ually damages the distributor drive. If you see any mis-  
alignment, adjust the posts and ramps until the discharge tube  
at the end of the arm stops over each bottle.

tions on page 2-1 show you how to remove  
the controller and replace the extensions  
for each bottle kit.  
Next, adjust the distributor arm to position  
D for the 12-bottle and 24-bottle kits, or to  
position B for the 8-bottle kit. Install the  
arm and stop. See Installing the Distribu-  
tor Arm and Discharge Tube on page 2-2.

Use the 5 /4-inch extension for the 2-bottle  
kit. The instructions on page 2-1 show you  
how to remove the controller and replace  
the extensions for each bottle kit.  
Next, replace the controller, and adjust the  
distributor arm to position A. Install the  
arm and stop. See Installing the Distribu-  
tor Arm and Discharge Tube on page 2-2.  
Install over the mounting plate at the bot-  
tom of the refrigerator, the locating base  
1
which holds the 2 /2-gallon glass or 2 gal-  
lon polyethylene bottles.  
Begin by loosening the ramps. Move them  
toward the front of the compartment so  
that they will fit under the ridge of the lo-  
cating base. (You can also remove them  
completely.)  
Remove the two front stops, and align the  
holes on the sides of the locating base  
with the holes for the stops in the mount-

Figure 2-4 Installing the 2-bottle Kit  
2.2.2 Removing Racks  
Before removing the rack, place the lids on the bottles so the  
samples do not spill. Remove the bottle rack by lifting the front  
edge of the rack slightly to disengage it from the two ramps.  
Then, pull it straight out of the refrigerator. Be careful not to  
catch the distributor arm against the bottles.  
2.2.3 Installing Composite  
Bottles  
Remove the distributor arm and discharge tube. Remove the dis-  
tributor arm stop. If using the two bottle locating base, remove it.  
Slide the composite bottle discharge tube on the bulkhead fitting.  
Composite bottle kits have two lids, one with a hole drilled in the  
center. Screw the lid with the hole in it on the bottle, and place  
the bottle in the center of the mounting plate.  
Thread the discharge tube through the hole in the lid. Always  
use the lid to retain the discharge tube. It prevents the sampler  
from spraying liquid inside the sample compartment instead of  
the bottle.

6712SR Refrigerated Sampler  
Section 2 Installation/Preparation  
2.3 Suction Line  
The suction line is the tubing from the sampling point to the  
pump intake. The 6712SR uses a /8-inch ID suction line of  
3
lengths 3 to 99 feet. Teledyne Isco offers vinyl or Teflon® suction  
lines. The Teflon® tubing has a polyethylene jacket to protect it  
from kinks and abrasions.  
The vinyl line contains a very low parts-per-million level of  
phenols. If phenol content affects your sample analysis, use the  
Teflon suction line.  
When installing the sampler, be sure the vertical distance  
between the liquid level and the pump is as small as possible.  
2.3.1 Guidelines for  
• Cut the line to the desired length but use the shortest  
length feasible for the installation.  
Measuring and Cutting  
the Suction Line  
• Cut the line in 1 foot increments. For instance, 4 feet,  
1
not 3 /2. If using metric units of measure, cut the line in  
increments of 0.1 meter. Do not include the length of the  
strainer in the measurement.  
2.3.2 Attaching Suction Line  
to Pump Tube  
Attach the vinyl suction line to the pump tube with the tube cou-  
pling. Use the black clamp for the pump tube and the white  
clamp for the suction line. Attach the line and tube to the cou-  
pling by pushing them onto each end of the coupling. Then  
tighten the clamps by squeezing the finger pads together. Loosen  
a clamp by twisting it until its teeth disengage.  
Attach the Teflon® suction line to the pump tube by inserting the  
line into the tube and secure with a suitable clamp.  
Attaching Suction Line Tube Coupling  
2.4 Strainers  
Teledyne Isco offers three styles of strainer that help prevent  
solids from clogging the suction line:  
3
/8-inch standard weighted polypropylene strainer for  
routine and priority pollutant sampling  
3
/8-inch stainless steel low flow strainer  
• Weighted, CPVC-coated strainer for acidic liquid sources  
To select the right strainer for your application, see Table 2-2. To  
install the optional low flow strainer in Teflon suction line, heat  
the end of the suction line to make it more pliable, then carefully  
screw the strainer’s threaded connector into the suction line.  
2.4.1 Alternative to Strainers When sampling from high velocity streams with heavy sus-  
pended solids, some field investigations suggest that more repre-  
sentative samples are obtained without the strainer. Consider  
attaching a short piece of thin walled aluminum tubing to the  
end of the suction line; anchor the tubing so that the inlet opens  
upstream. The aluminum tubing’s thin wall will not disturb the  
flow stream, and most sample analyses disregard aluminum  
ions. Under most conditions, the pre-sample purge removes any  
debris over the tubing entrance.

Teflon suction line is compatible only with the /8 stainless steel strainer.  
2.5 How Does the Sampler When the sampler takes a sample, it draws liquid through the  
strainer and suction line to the pump tube. The liquid flows  
Work?  
through the pump tube and past the liquid detector, which senses  
the liquid. From the detector, the liquid follows the pump tube  
through the pump to the bulkhead fitting and then through the  
discharge tube to the sample bottle.  
A typical sampling cycle consists of:  
1. The sampler moves the distributor arm over the bottle that  
is to receive the sample.  
2. The pump reverses for the pre-sample purge.  
3. The pump direction changes, filling the suction line.  
4. When the detector senses liquid, the sampler begins mea-  
suring the sample.  
5. After depositing the sample, the pump again reverses for  
the post-sample purge.  
Sampling cycles vary somewhat according to program settings  
for distribution. The sampler can move the distributor arm  
clockwise and counterclockwise, making a number of distribution  
methods possible. (In this manual, the words “sample event”  
refer to a full sampling cycle for any distribution.)

Other variations include extended-program settings for  
suction-line rinses and sampling retries. A sampler running a  
program with line rinses completes the pre-sample purge and  
then rinses the line. The suction line is purged after each rinse.  
When programmed for sampling retries, the sampler will  
attempt to pump a sample again if it fails on previous attempts.  
2.5.1 Measuring Sample  
Volume  
“Sample volume” refers to the amount of liquid delivered into a  
bottle. The volume is determined by the programmed value. The  
volume is dependent on the volume per revolution of the pump,  
which is dependent on the suction head. The 6712SR delivers the  
sample by counting the pump revolutions and automatically  
compensating for the suction head.

6712SR Refrigerated Sampler  
Section 2 Installation/Preparation  
2.6 Installing the Sampler The following segment briefly describes initial sampler instal-  
lation.  
CAUTION  
Tests indicate that the pump produces sound levels in excess  
of 85db at one meter. Prolonged exposure to this sound could  
result in hearing loss and requires the use of protective ear  
plugs.  
CAUTION  
When using the 6712SR sampler with a 750 or 710 module,  
transmitters such as cell phones or walkie talkies must not be  
operated within 3 meters of the sampler. If water level readings  
are fluctuating due to TV/radio station transmitter towers in the  
area, the sampler must be relocated.  
WARNING  
The 6712SR samplers have not been approved for use in  
hazardous locations as defined by the National Electrical  
Code.  
WARNING  
If you must enter a manhole or other dangerous location to  
install the sampler, observe standard safety precautions.  
Refer to Appendix C for a discussion of safety  
considerations.  
2.6.1 Tips for Routing  
Suction Line  
Route the line so that it runs continuously downhill from the  
sampler to the liquid source. This helps drain the line during  
pre-sample and post-sample purges. When the sampler is used in  
below freezing temperatures, there is a risk of the suction line  
being frozen. A suitably warm sampling source can usually  
prevent this, provided there are no loops in the suction line.  
Some situations may require more protective measures, such as  
insulation of the suction line, or heat tape. Thoroughly draining  
the suction line minimizes the possibility of frozen liquid  
clogging the line.  
2.6.2 Intake Placement  
For representative samples, place the intake in the main current  
of the flow stream, not in an eddy or at the edge of flow. Placing  
an intake at the bottom may produce samples with excess heavy  
solids and no floating materials, while placement at the top may  
produce the opposite conditions.  
2.6.3 Positioning a Sampler  
Place the refrigerator on a relatively flat, horizontal surface.  
Placing the refrigerator on a steep incline may cause the sample  
to miss the bottle mouth.

6712SR Refrigerated Sampler  
Section 2 Installation/Preparation  
When installing the sampler, be sure the vertical distance  
between the level of the liquid and the pump is as small as pos-  
sible.  
CAUTION  
The refrigerator’s lower compartment is not watertight. Do not  
install in a location where the refrigerator’s lower compartment  
could become submerged.  
2.7 Connecting External  
Instruments  
The 6712SR sampler can be used in conjunction with several  
types of external instruments.  
2.7.1 Flow Meter  
To connect the sampler to a teledyne Isco open-channel flow  
meter, 4100 series flow logger, 2100 series flow module, or 1640  
Liquid Level Actuator, attach the sampler-to-flowmeter cable to  
the Flow Meter Connector. To connect the sampler to a  
closed-pipe flow meter, attach a teledyne Isco 4-20 mA Input  
Interface device to the sampler’s Flow Meter connector. Plug the  
line cord into an AC power outlet. Be sure it is connected to 120  
volts AC (optional 230 volts AC). When using the sampler with  
an external instrument, remember these guidelines:  
Flow Meter Connector Icon  
• Both the sampler and the flow instrument must be on  
and running a program.  
• If using a flow meter, logger, or module for flow pacing,  
the sampler and the flow instrument must both run  
programs with flow pacing settings.  
• If using a flow meter or flow logger for trigger pacing,  
the sampler must run a program with flow pacing  
settings, and the flow instrument must run a program  
with trigger pacing settings.  
• When the sampler runs an event-paced program, it  
disregards pacing pulses from a flow meter or flow  
logger. However, the sampler continues to monitor for  
enable signals.  
2.7.2 Rain Gauge Connector  
Connect the rain gauge, SDI-12 Sonde, or Refrigerator Temper-  
ature Sensor connect cables to the nine-pin Rain Gauge Con-  
nector. When connecting a rain gauge and an SDI-12 Sonde, or  
rain gauge and a Refrigerator Temperature Sensor, use the  
appropriate Y-connect cable. See the Accessories appendix at the  
end of this manual.

2.8 Locking the Sampler  
2.9 Servicing the Sampler  
The refrigerator is equipped with a lockable latch for the top  
cover and a lockable catch for the door handle. To lock the refrig-  
erator, use two padlocks, one for the top cover and one for the  
door.  
Servicing the sampler includes:  
• Collecting the filled sample bottles and replacing them  
with clean bottles;  
• Collecting the data recorded by the sampler during the  
program.  
Samplers are usually serviced after they complete a sampling  
program. When working up a service schedule, you will need to  
estimate the program completion time. You should also be  
familiar with the program’s settings for the start time or if the  
sampler is programmed for continuous sampling.  
Continuous sampling is controlled by the distribution setting  
entered at the “RUN CONTINUOUSLY?” screen. A “YES”  
response directs the sampler to reset the distribution sequence  
and continue the countdown to the next sample event. Appro-  
priate service intervals will prevent overfilled bottles.

6712SR Refrigerated Sampler  
Section 3 Getting Started  
Before programming the 6712SR, you should become familiar  
with its keys and how to use the screens.  
The 6712SR Sampler has two sets of programming modes. The  
first mode, Standard Programming, lets you set up typical  
sampling programs easily and efficiently. The second mode,  
Extended Programming, lets you create sophisticated pro-  
grams for complex sampling applications.  
All of the sampling features available in standard programming  
mode are available in extended programming mode. However,  
extended programming provides many additional features.  
Standard and extended programming features are explained in  
separate sections. This section focuses on some basic features  
that are common to both programming modes, such as using the  
menus and setting the clock.  
3.1 Initial Operation

The sampler will continue to use the program mode you selected,  
even if the sampler is turned off and on again, until you man-  
ually switch to the other programming mode.  
With the display backlight activated, the screen will glow for  
several seconds following your last keystroke.  
If you press a key and the screen text does not change, it is  
probably because the keystroke turned the backlight on, instead  
of performing its function. Press the same key again.

between two quotation marks. Lines 2 and 3 contain the menu  
options — numbers, letters, and punctuation marks — used to  
spell out the description. In line 3, the space between the  
ampersand (&) and the double quotes (") is a space character.  
Line 4 contains two additional options:  
• BACK-UP, an option that moves the cursor on the text  
line to the left one character.  
• DONE, an option that tells the sampler to save the text.

3.6.3 Warning Messages  
Warning messages appear when the sampler determines some-  
thing is out of the ordinary. For example, the following warning  
appears when you type a number that is larger than the  
standard bottle volume:  
BOTTLE VOLUME IS  
3500 ml (300-30000)  
WARNING!  
STANDARD BOTTLE  
VOLUME EXCEEDED!  
The 6712 does accept nonstandard volumes because you might  
use a nonstandard container occasionally. For a list of recom-  
mended volumes for Teledyne Isco bottles press the ? (Help) key  
at the “Bottle Volume Is” screen, or refer to the Technical Specifi-  
cations.  
The 6712 uses the bottle and sample-volume settings to  
determine the maximum number of samples that can be  
deposited without overfilling the bottles. Entering a volume that  
exceeds the standard volume may cause the sampler to overfill  
the bottle.  
3.6.4 Operation Messages  
An operation message reports the sampler’s status as it runs a  
program. An example is shown below.  
PROGRAM WILL START  
AT 06:00 TU 20-FEB  
05:56:22 TU 20-FEB  
3.7 Menu Trees  
Selecting a menu option will take you to a number-entry screen  
or another menu screen. The screens are organized in a  
branching structure that resembles a tree. Refer to Figure 3-1 for  
a simple chart of the menu tree for standard programming. The  
standard programming structure is different — much simpler —  
than the extended programming structure. Charts that show you  
most of the sampler’s screens appear in Appendix A.  
The entire structure changes a little when a module is attached  
because the sampler adds a set of screens for a module as soon as  
it detects the module’s presence. The manuals for each module  
contain menu trees for its programming screens.

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
The 6712SR Sampler has two sets of programming screens. The  
first set, called standard programming screens, lets you set up  
typical sampling programs easily and efficiently. The second set,  
extended programming screens, lets you create sophisticated  
programs for complex sampling applications.  
All of the sampling features available within the standard pro-  
gramming screens are available in extended programming.  
However, extended programming provides several additional fea-  
tures which are discussed in the next section. Menu flowcharts  
for both sets of programming screens are in Appendix A.  
4.1 Switching Between  
Standard and  
Factory default settings cause the sampler to begin in standard  
programming mode the first time you turn it on. The start-up  
screen tells you which programming mode the sampler is cur-  
rently using. You can switch between programming modes by  
entering a numerical command at the main menu:  
Extended Modes  
• At the main menu, type 6712.1 to enter standard  
programming mode.  
• At the main menu, type 6712.2 to enter extended

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
4.4 Pacing  
Sample pacing is the rate at which the sampler takes samples.  
Depending on the type of pacing you select, the rate is controlled  
by the sampler’s internal clock or by inputs received from con-  
nected instruments.  
Standard Time Pacing and  
Flow Pacing Screens for  
Samplers without Flow  
Modules  
Standard programming provides time pacing and flow pacing  
(refer to Step 7 in the previous two programming examples). In  
time-paced sampling, the interval between samples is a constant  
time interval. When you program the sampler for time pacing,  
the sampler prompts you to enter the time between sample  
events in hours and minutes. Time paced programs always take  
a sample at the start time.  
TIME PACED  
FLOW PACED  
• When programming, you will  
be asked to select time or flow  
paced sampling. Depending  
upon your choice, you will see  
one of the following screens:  
Flow paced sampling requires a flow meter, flow logger, or a  
module. A flow meter or flow logger paces a sampler by sending  
an electronic signal to the sampler after measuring a specified  
volume of liquid. Because each pulse represents a volume  
interval, flow pacing rates are proportional to the volume of  
water flowing through the channel.  
TIME BETWEEN  
SAMPLE EVENTS:  
__ HOURS, __ MINUTES  
FLOW BETWEEN  
SAMPLE EVENTS:  
____ PULSES (1-9999)  
When you program the sampler for flow pacing and are using a  
flow meter or flow logger, the sampler prompts you to enter the  
interval between sample events in pulses. The sampler initiates  
a sample event when the set number of pulses is received. Pro-  
grams that are flow paced do not take a sample at the start time.  
After setting the program start time, you will be prompted to  
enter a maximum run time of zero to 999 hours. If you would like  
the program to run indefinitely, enter 0 (zero) for maximum run  
time.  
Flow Pacing Screen for  
The flow pacing screens change when you attach a flow module  
(see example to the left). Because the sampler is more closely  
integrated with the modules, the standard flow pacing screen  
prompts you for the flow volume between sample events instead  
of pulses between events. The flow volume units displayed are  
what you had previously programmed.  
Samplers with Flow Modules  
FLOW BETWEEN  
SAMPLE EVENTS:  
____ Mgal  
(0.001 -99999)  
4.4.1 Trigger Pacing  
Teledyne Isco 4200 Series Flow Meters and 4100 Series Flow  
Loggers send pulses for trigger pacing. The flow meter or flow  
logger sends pulses at two different time intervals when trigger  
pacing a sampler. Trigger pacing, for example, lets you sample  
less frequently when the trigger condition — a condition based  
on level, flow, or rainfall — remains below a set point. The  
intervals are determined by the flow instrument’s program set-  
tings for trigger pacing.  
When conditions change and readings pass the set point, trig-  
gering the new rate, you can sample more frequently. Or, when  
the trigger condition is a clock setting, the instrument changes  
the pacing interval according to the time of day. Using a clock  
trigger condition, for instance, the flow meter or flow logger can  
pace the sampler slowly at night and more frequently during the  
day. (For more information about trigger pacing, see your flow  
meter or FLOWLINK manual.)

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
The flow meter or flow logger sends the same pulse for both flow  
and trigger pacing, and the sampler cannot distinguish between  
them. Therefore, to program a sampler for trigger pacing, simply  
program it for flow pacing.  
4.5 Distribution  
Distribution describes how the sampler is to deposit samples. A  
sample is the volume of liquid deposited in a bottle. A sample  
event includes the full sampling cycle and may deposit a sample  
into more than one bottle.  
In standard programming, you can program the sampler for  
these different distribution methods:  
• Sequential  
• Bottles Per Sample  
• Samples Per Bottle  
• Composite  
4.5.1 Sequential  
In sequential distribution, the sampler deposits one sample in  
each bottle. A sequential sample represents a “snapshot” of the  
flow stream at a point in time.  
4.5.2 Bottles Per Sample  
In bottles per sample distribution, the sampler deposits a sample  
in each of a set of bottles. A bottle set includes at least two bottles  
but may include all bottles. Use bottles per sample when the  
volume to be collected is larger than the amount one bottle can  
hold or when you need identical samples.  
4.5.3 Samples Per Bottle  
4.5.4 Composite  
In samples per bottle distribution, the sampler deposits samples  
from several sample events in a single bottle before moving to the  
next bottle. Use samples per bottle distribution to collect a series  
of small composite samples.  
For single bottle configurations, samples per bottle distribution  
is known as composite sampling. A composite sample represents  
an average of the flow stream’s characteristics during the sam-  
pling period.  
4.5.5 Continuous Sampling  
Sample programs can be run indefinitely by selecting “YES” at  
the “RUN CONTINUOUSLY?” screen. Continuous sampling  
resets the distribution when the distribution sequence is com-  
plete. That is, when the last bottle/set is reached, the next  
bottle/set is the first bottle/set. All pacing modes except  
RANDOM are supported.  
When running a program continuously, the bottles must be ser-  
viced at regular intervals to prevent overfilling the bottles. The  
sampler assumes that the next bottle/set is empty and ready to  
receive samples.  
The figure on the next page steps through the programming  
screens for sequential, bottles per sample, and samples per bottle  
distribution.

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
4.6 Start Times  
It is important to understand the difference between the time at  
which you run a program and the program’s start time. Running  
a program simply means selecting RUN from the sampler’s main  
menu. The start time is the time at which the sampler begins the  
program’s first sample interval countdown. The start time is con-  
trolled by your selections from the start time screens.  
Each program contains start-time settings that tell the sampler  
when to begin the program. When programming the sampler, you  
can select one of four start time options: NO DELAY TO START,  
DELAYED START, CLOCK TIME or WAIT FOR PHONE CALL.  
• Select NO DELAY TO START when you want the  
sampler to start as soon as you select RUN.  
• Select DELAYED START when you want the sampler to  
delay from 1 to 999 minutes before starting the  
program.  
• Select CLOCK TIME when you want the sampler to  
begin the program at a specific time on at least one day  
of the week.  
• Select WAIT FOR PHONE CALL when you want the  
sampler to begin the program after receiving a remote  
command to start.  
4.6.1 How Do Start Times  
Work?  
As soon as you select RUN from the main menu, the sampler  
checks the program’s start time settings. With a “DELAYED  
START” setting, the sampler starts a countdown to the start  
time. The period between the time you select RUN and the start  
time you’ve specified in the program is called the “delay to start  
time.”  
When you run a program with “CLOCK TIME” settings, the  
sampler also starts a countdown to start time until the day of  
week and clock times are met.  
The sampler may not collect a sample at the start time. The  
sampler must be enabled, and the pacing selected must call for a  
sample at start. In any event, the sampler checks the pacing set-  
tings and begins the pacing-interval countdown.

4.6.2 Sampler  
Enable/Disable  
Teledyne Isco flow meters and flow loggers have a programmable  
sampler-enable feature that lets them enable (start) or disable  
(stop) a program according to certain monitored conditions. For  
example these conditions can be level, flow rate, pH, temper-  
ature, percent, rainfall, I/O; or a combination of two conditions.  
The 1640 Liquid Level Actuator can also be used, as well as any  
other instrument that can ground the input to pin F. Grounding  
the input disables the sampler.  
The sampler disregards disable signals during the delay to start  
time. However, when the sampler detects a disable signal at the  
start time, it suspends the program until it is enabled. The  
diagram in Figure 4-2 shows the sampler’s responses.

4.7 Running Programs  
To run a program, select RUN from the main menu. You may also  
select YES at the RUN THIS PROGRAM NOW? screen at the  
end of the programming screens.  
4.7.1 Run Time Screens  
While running a sampling program the sampler displays a  
variety of messages that report the program’s status. For  
example, if the sampler has not yet reached the programmed  
start time, it displays the scheduled start time as well as the  
current time.  
Once the program reaches the start time, you can determine the  
time of the next sample, the next bottle to receive a sample,  
sample distribution, and other information. Other messages  
appear while the sampler runs through a sampling cycle and  
takes a sample. When the sampler needs to report multiple mes-  
sages, it alternates them, displaying each for one to three  
seconds.

Samplers with an attached module display the module’s  
readings: pH and temperature for the pH module; level, per-  
centage, or flow rate for the 4-20 mA module; level, flow rate, and  
flow volume readings for the flow modules; level, velocity, flow  
rate, and positive flow volume readings for the area velocity  
module. Some module screens will alternate with the sampler  
screens.

An * (asterisk) appears next to the reading if the module was  
unable to take a reading. If an asterisk appears, the reading dis-  
played is the last available reading. Flow rates will be reported  
as zero flow if the error persists for more than five minutes (for a  
level or velocity reading that flow is calculated from).  
If an entire reading is filled with asterisks, the value exceeds the  
number of characters that can be displayed. The sampler stores  
the actual reading in memory, so it may be collected later.

For those programs that have delayed or scheduled start times,  
the readings will be displayed while waiting for the start time.  
Keep in mind that any totalizer values will be reset at the start  
time. Module and sonde readings are also displayed after a  
program is complete, until a key is pressed.  
It is not necessary to run a program to view module or sonde  
readings. Real time data can be viewed on the display by  
selecting “VIEW REPORT” from the main menu.  
4.8 Interrupting a  
Running Program  
You can interrupt a sampling program by pressing the Stop key  
while the sampler is waiting for the next sample event. Pressing  
Stop places the sampler into Manual Paused operation and  
records a manual pause in the sample event log.  
In this state, the sampler allows you to access several functions.  
You can modify the program, reset alarms, take a grab sample,  
etc., without adversely affecting the running program. Modifying  
the program is limited to adjusting the pacing intervals, enable  
conditions and sample volume. The basic program structure,  
such as the type of pacing, can not be changed.  
While in the manual paused state, the sampling program con-  
tinues to operate as normal, with the exception of taking  
samples. If a sample was to be taken, it is skipped. The sampler  
records “sample skipped” in the sample event log and continues  
to operate as normal.  
The manual paused state displays a scrolling menu with several  
options (see example below). Use the Arrow keys to scroll  
through the manual paused options and the key to make a  
selection. Return to the running program by selecting resume  
program or pressing the Stop key. If you do not make a selection,  
the sampler automatically resumes the original sampling  
program five minutes after the last key was pressed.

resume event will be logged.  
4.8.3 View Data  
This option allows you to view the data recorded by the sampler.  
See Reports on page 4-19 for more information.  
4.8.4 Grab Sample  
When selected, you will be asked to enter the volume to be  
pumped. A sample will then be taken as if it is to be placed into a  
container outside the sampler base. Do this by removing the  
pump tubing from the bulkhead fitting. See Grab Samples on  
page 4-15. A grab sample event will be logged.  
4.8.5 Pump Tube Alarm  
4.8.6 Calibrate Volume  
If the pump tube is changed, this option should be selected to  
reset the pump counts on the counter. This will remove the  
“WARNING: REPLACE PUMP TUBING” message that may  
appear while the program is running. A pump tube replaced  
message is logged. See Replacing The Pump Tube in Section 7,  
Maintenance.  
When selected, you will be asked to enter the volume to be  
pumped. A sample will then be taken as if it is to be placed into a  
container outside the sampler base. Do this by removing the  
pump tubing from the bulkhead fitting.  
After the sample has been pumped, you will then be asked to  
enter the amount actually delivered. Once you have entered the  
delivered volume and accepted the calibration, a volume  
delivered event will be logged.  
4.8.7 Cal/Adj Parameters  
When the sampler is configured for operation with a module, this  
option becomes available. Selecting this option will display the  
appropriate level adjustment screens and/or the calibration  
screens. If the level is adjusted, an adjusted level event is logged.  
If a parameter is calibrated, an appropriate event is logged.  
Calibrating a parameter probe will temporarily “turn offthe  
partition data storage and the sample enable/disable functions.  
These functions are disabled during the calibration and for five  
minutes after the program is resumed. During this time,  
parameter data normally collected at the data storage interval  
will be logged as a 252 error message.  
4.8.8 Adjust Pacing  
This option is available when the running program is paced by  
Time, Flow Pulses or Flow Volume. If you select this option, you  
are asked to enter a new pacing interval. The sampler logs an  
interval changed event.  
The original pacing interval continues to count down until you  
return the sampler to the running program (select resume  
program). If the new pacing interval is less than the original  
count remaining, the new interval is used.

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
If the original count remaining is less than the new pacing  
interval, the original count will continue to count down to the  
next sample event. Subsequent samples are then paced by the  
new interval.  
4.8.9 Adjust Volume  
4.8.10 Power Used  
Select this option to change the sample volume within the limits  
of the currently programmed sample distribution. If you change  
a sample volume, a volume changed event is logged.  
The 6712 has a “fuel gauge” that gives an indication of power  
usage. The controller keeps track of how much power has been  
consumed since the last time it lost power. If the controller is  
powered by an external battery, this fuel gauge can help you  
estimate the condition of the battery.  
Keep in mind that the sampler has no idea as to how much  
charge was originally stored in the battery (or even if a battery is  
being used), and therefore has no idea as to the remaining  
capacity of its power source.

4.11 Grab Samples  
Grab samples let you take a single sample on demand, collecting  
the sample in an external container (Figure 4-4). Keep in mind:  
When the sampler delivers a grab sample, it runs through a com-  
plete sampling cycle, using the current settings for volume and  
for line rinses or retries. If it is a two-part program, the sampler  
uses the settings for part A.

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
4.12 Calibrate Volume  
The sampler delivers accurate sample volumes without cali-  
bration. If you find that sample volumes vary significantly from  
the programmed values, first check the suction line for proper  
installation. Be sure it slopes continuously downhill to the liquid  
source and drains completely after each sampling cycle. Then,  
compare the actual length of the suction line to the suction line  
length settings in the program to see that they match. Also check  
the pump tube for excessive wear and replace it if necessary.  
You may want to calibrate when:  
• A new pump tube is installed. Run the pump for five  
minutes before calibrating.  
• The sample source is above the sampler.  
• Sampling from pressurized lines (15 PSI Maximum).  
4.12.1 Calibration Tips  
• For the best results, calibrate the sampler after it’s  
installed on site.  
• Use a graduated cylinder for volume measurement.  
• The sampler clears the previous calibration setting  
when you reinitialize the sampler.  
You cannot calibrate while the sampler is running a  
program.  
• When the sampler delivers the sample, it runs through a  
complete sampling cycle, using the current settings for  
volume line rinses and retries. If it is a two part  
program, the sampler uses the volume setting for part  
A.  
To calibrate:  
1. Disconnect the pump tube from the bulkhead fitting.  
2. Place the end of the tube over a collection container.  
3. Follow the steps in Calibrating Sample Volumes in the  
margin.  
4. Reconnect the pump tube to the bulkhead fitting.

4.13 Operating the Pump  
You can manually operate the sampler’s pump in the forward or  
reverse direction. You can do this to test the pump, draw a large  
sample, or purge the suction line.  
When you run the pump manually, the sampler reports the  
number of pump counts during the pump’s operation. Use this  
feature to obtain an estimate of the pump counts required to  
purge a nonstandard suction line.  
You can also manually run the pump from the main menu. Press  
the “1” key and then to run the pump in reverse. Press the “3”

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
4.15 Reports  
The 6712 records a variety of data while running a sampling  
program. It uses the data to produce four reports:  
• The Program Settings report, listing the program  
settings.  
• The Sampling Results report, listing the program  
settings, time of samples and other program events.  
• The Combined Results report, combining the sample  
event times with rainfall or module data.  
Interrogator Icon  
• The Summary report, listing daily summaries of data  
collected. The Summary report may be rainfall and/or  
module data.  
The sampler stores the data for each report in memory where  
they remain until you select RUN. Selecting RUN clears the  
memory so that it can store the data from the next program.  
4.15.1 Collecting Reports  
There are a number of ways to collect the reports:  
View reports (program settings, sampling results, and abbre-  
viated summary reports) on the sampler’s display.  
Collect the reports (except for summary reports) with a teledyne  
Isco 581 RTD and use a computer running flowlink or samplink  
to transfer the reports from the RTD to a file on the computer.  
Collect the reports (except for summary reports) with an IBM PC  
or compatible computer running flowlink.  
Collect the reports with and IBM PC or compatible computer  
running samplink.  
581 RTD  
4.15.2 Viewing the Data  
Because the display area is small, the data on the reports will be  
displayed a little differently from the data that is transferred to  
and viewed on your computer.  
• For the Sampling Report, the sampler displays each  
program event, one at a time.  
• For the Module and Rainfall Data reports, it displays  
daily summaries, instead of the full reports available  
with the rtd, Flowlink, or Samplink.  
If you select Sampling Report or Rainfall (step 3 in Viewing Data,  
shown in the margin), the sampler begins displaying the report  
data. The sampler advances automatically through the report  
items, displaying each item briefly. While the sampler advances  
automatically through the displays:  
• Stop the automatic displays by pressing Stop once.  
Then, use the arrow keys to move manually through the  
report.  
• Return to the main menu by pressing Stop twice.  
At the end of the report, the sampler leaves the last item dis-  
played until you press:  
• the arrow keys to move forward or backward manually  
through the report.  
• Stop to return to the main menu.

6712SR Refrigerated Sampler  
Section 4 Standard Programming  
4.15.4 Sampling Results  
Report  
As the sampler runs a program, it records the program’s events.  
Program events include such items as sample events, program  
enables and disables, power losses, and so on. Table 4-3 lists each  
event with a short description. You can view the report by fol-  
lowing the steps in Viewing the Data on page 4-19 or print the log  
as the Sampling Results report.  
In the text file version of the report, sample-event entries include  
the time of the event as well as the sample and bottle numbers.  
The sample column contains the sample number deposited into  
the bottle. This information reflects the distribution selected for  
the program.  
The letters in the Source columns are codes for the cause of the  
event. The letters in the Error column are codes for the causes of  
missed samples. The source and error codes appear with expla-  
nations at the end of the report. A list of codes appears in Table  
The last column in the Sampling Results report records the  
pump counts for the sample event. Large variations in pump  
counts from event to event indicate fluctuating heads, a relocated  
suction line, or a temporarily clogged strainer.  
4.15.5 Combined Results  
Report  
At the time of each sample event, the sampler records the  
readings from each connected module, rain gauge, or SDI-12  
sonde. The Combined Results Report presents the event time,  
sample and bottle number, and the respective readings from the  
device.  
For flow modules, the readings are level and flow rate. For the  
pH module, the readings are temperature and pH. For the rain  
gauge and SDI-12 Sonde, the readings vary according to the  
selections enabled during the hardware setup in extended pro-  
gramming. When recording four or more sonde parameters, the  
Combined Results report will exceed the standard 40 character  
width. To read the additional columns, the data must be collected  
with Flowlink 4 for Windows software.  
4.15.6 Summary Report  
This report summarizes the rain gauge or module data. The  
types of readings are the same as those available to the Com-  
bined reports. The sampler compiles the data to present a daily  
total, the day’s average, maximum, and minimum reading, and a  
listing of hourly averages. The sampler then graphs the day’s  
readings.

SYSTEM IDs  
The model and ID numbers remain unchanged through the life of  
the sampler. The ID numbers appear on the sampler’s reports  
and in files created by flowlink and samplink when they inter-  
rogate the sampler. The software packages use the ID number to  
make sure that data from different samplers is not combined in  
the same file.

4.17 Programming for 700  
Series Modules  
The bay on the controller’s side accepts any of Teledyne Isco’s 700  
Series Modules. These modules are optional accessories that are  
not required for operation of the 6712. However, the modules  
offer an economical way to combine flow-rate or parameter moni-  
toring with sampling.  
The programming of these modules is integrated with the pro-  
gramming of the sampler, so attachment of a module will cause  
different screens to be displayed, depending on the type of  
module and the selections you make while programming.  
Two modules that are commonly used are the 730 Bubbler  
Module, which monitors a flow stream’s level and flow rate, and  
the 750 Area Velocity Module for monitoring a flow stream’s  
level, velocity, and flow rate. The following sets of screens give  
you an example of what screens you might see while pro-  
gramming the sampler and module. Refer to Table 4-1 (which  
does not have a module attached) at the beginning of this section  
to compare the sequence of screen displays.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
The 6712SR Sampler has two sets of programming screens. The  
first set, called standard programming screens, lets you set up  
typical sampling programs easily and efficiently. The second set,  
extended programming screens, lets you create sophisticated  
programs for complex sampling applications.  
All of the sampling features available with standard pro-  
gramming screens, discussed in Section 4, are available with  
extended programming screens. However, the extended screens  
provide several additional features and some screen display dif-  
ferences which are discussed in this section. The menu flow-  
charts for both sets of programming screens are in Appendix A,  
Menu Flowcharts.  
Note  
This section assumes that you have read, and are familiar  
with, the instructions in Section 4, Standard Programming!  
5.1 Extended and  
Standard Mode  
The sampler is shipped with factory default settings in standard  
programming mode when you first turn the sampler on. The  
start-up screen tells you which programming mode the sampler  
is currently using. You can switch between programming modes  
by entering a numerical command at the main menu:  
At the main menu type 6712.2 to enter extended programming  
mode.  
At the main menu type 6712.1 to enter standard programming  
mode.  
RUN “EXTENDED 1”

5.2 One-Part and  
Extended programming lets you set up a “one-part” program or a  
“two-part” program. One-part programs let you fill all bottles of  
the tub with one set of pacing, distribution, and enable settings.  
Two-part programs add an additional set of extended pacing, dis-  
tribution, and enable screens to the sampling program. Each set  
of screens is called a program part. The program parts are simply  
called part ‘A’ and part ‘B’. Both parts share the program settings  
for suction-line length, suction head, and rinses and retries. They  
also share one start-time setting.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
Each part has its own group of bottles. Because settings for each  
part are independent of each other, the sampler, when running a  
two-part program, fills each bottle group as if they were being  
filled by two different programs. Two-part programs finish when  
both parts are done.  
Two-part programming is ideal for sampling storm events. Many  
storm-water run-off monitoring permits require a first-flush grab  
sample within the first 30 minutes of the storm event and  
flow-paced samples during the remainder of the event. With a  
two-part program, you can set up part ‘A’ for the first-flush  
sample and part ‘B’ for the remainder. Table 5-2 shows a  
storm-water sampling program.  
5.3 Storage for Extended  
Programs  
The sampler stores five sampling programs: one standard and  
four extended. Program storage eliminates the need to  
reprogram the sampler with frequently used settings. This  
feature is especially useful for complex extended programs such  
as two-part programs or programs with many nonuniform-time  
settings.  
Teledyne Isco ships the sampler to you with factory programs  
that you can modify to suit your own needs. All four extended  
programs are identical to each other.  
The stored programs will also save your 700 Series Module  
program settings and any sampler enable conditions using rain  
gauge data or SDI-12 sonde parameters. These program settings  
remain as long as you do not change the type of module, or  
change the rain gauge or SDI-12 Hardware Setup.  
5.3.1 Selecting a Stored  
Program  
When the sampler is in extended programming mode, it always  
has one current and three noncurrent programs, each occupying  
a permanent location in memory. The first time you access the  
extended mode, the current program is “EXTENDED 1,” one of  
the factory extended programs. The name of the current  
extended program appears in quotations on the first line of the  
main menu.  
The factory programs are named “EXTENDED 1,” “EXTENDED  
2,” “EXTENDED 3,” and “EXTENDED 4." You can rename them  
with more descriptive names, making them easier to identify.  
The program name is one of the extended program’s settings.  
After selecting a stored program, review the settings with the  
quick view screens. Each sampling program stores all the set-  
tings required by the sampler to run a program. These settings  
include the bottle-kit information (number of bottles and the  
bottle volume), the suction-line length, the site description, start  
times, and so on.  
If you use the same program at two sites — each requiring dif-  
ferent bottle configurations, suction line lengths, or other details  
— always check these settings before running a program. You  
may need to make minor changes to the program to make sure  
the settings match your equipment.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
The current program is the program you see when you select  
PROGRAM from the main menu and page through the pro-  
gramming screens. It is the program the sampler uses when you  
select RUN from the main menu.  
You cannot delete programs, but you can modify them as often as  
necessary. To run a program with different settings without  
losing the settings in your current program, select a stored  
program and modify its settings.  
For example, assume you have been running the current  
program, named “EXTENDED 1,” at site A for several weeks.  
This program contains all the settings you need for site A, and  
you don’t want to lose those settings.  
Nevertheless, you need another program because you want to  
move the sampler to site B, so you select “EXTENDED 2” and  
modify it for site B. The settings in “EXTENDED 1” are pre-  
served automatically. When you return the sampler to site A, you  
won’t need to reprogram the sampler. Merely select  
“EXTENDED 1” again, double-check the program settings, and  
run the program. To select an extended program, follow the steps  
in Table 5-1.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.4 Programming for 700  
series Modules  
The bay on the controller’s side accepts any of Teledyne Isco’s 700  
Series Modules. These optional accessories are not required to  
operate the 6712. However, the modules offer an economical way  
to combine flow-rate or parameter monitoring with sampling.  
The programming of these modules is integrated with the pro-  
gramming of the sampler, so attachment of a module will cause  
different screens to be displayed, depending on the type of  
module and the selections you make while programming.  
Two modules that are commonly used are the 730 Bubbler  
Module, which monitors a flow stream’s level and flow rate, and  
the 750 Area Velocity Module for monitoring a flow stream’s  
level, velocity, and flow rate. Section 4 contains two examples of  
programming for modules. Module programming is the same in  
Extended as it was in Standard programming.  
5.5 Programming SDI-12  
Sondes  
As an option, the 6712 accepts up to 16 parameters from up to  
ten sensors with SDI-12 addresses from 0 - 9. The data param-  
eters used by the sonde and sampler must match. Certain  
vendors’ sondes, such as Hydrolab and YSI, have enhanced com-  
mands that facilitate “plug and play” setup. These Teledyne Isco  
Ready sondes can tell the 6712 what values they have, their  
order, and units of measure. Other sondes can be used, but  
require manual setup to identify proper data types for each data  
value reported.  
For more information about programming SDI-12 sondes, refer  
to Section 6.  
5.6 Programming  
Examples  
In addition to the features available with standard pro-  
gramming, and discussed in Section 4, extended programming  
offers:  
• Nonuniform time pacing  
• Random interval pacing  
• Event pacing  
• Multiple bottle compositing  
• Time switched bottles or bottle sets  
• Programmable sampler enable  
• Pauses and resumes  
• Two-part programming  
• Automatic or user-defined suction head  
• Suction line rinses  
• Sampling retries  
This manual provides several programming examples. Some,  
demonstrating simple tasks, appear in the margins. Others, dem-  
onstrating more complex tasks, appear as examples. Table 5-2 on  
the following pages steps you through a storm water runoff sam-  
pling using extended programming.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.6.1 Storm Water Runoff  
Sampling  
Storm water runoff sampling is an ideal application for two-part  
programming. Typical monitoring permits require that a series  
of timed samples be taken during the initial portion of the storm  
event, followed by flow paced samples during the remainder of  
the event.  
This example assumes that a Rain Gauge and a Bubbler Flow  
Module are connected to the sampler.  
Note  
To enable the Bubbler Module programming screens, insert  
the module before turning on the sampler  
Using a 24-bottle kit, it divides the bottles into two groups, with  
six bottles assigned to part ‘A’ and 18 to part ‘B.’ The sampler will  
begin taking samples after being enabled according to program-  
mable enable controls; that is, when the rain gauge detects 0.15  
inches of rainfall in 30 minutes, and the module detects a flow  
stream level of more than 0.25 feet. Because both program parts  
use the same enable settings, the sampler will enable both parts  
at the same time. A list of settings for the program follow:  
• Program type: Extended.  
• Program name: STORM.  
• Site description: SITE 54.  
• Units: Length – Ft, Flow Rate – gpm, Flow Volume – gal  
• Mode of Operation: Flowmeter, Flow-Insert, Round, 12"  
• Bottle kit: 24, 1000-milliliter bottles.  
• Suction-line length: 5 feet.  
• Suction head: Auto suction head.  
• Line rinses: None.  
• Sampling retries: None.  
• Part ‘A’ and ‘B’ bottle assignments: Bottles 1 - 6 to part  
‘A’, bottles 7 - 24 to part ‘B’.  
• Part ‘A’ pacing: Time pacing, sampling every 5 minutes.  
• Part ‘A’ distribution: Sequential, 1 sample per bottle.  
• Part ‘A’ sample volume: 800 milliliters.  
• Part ‘A’ enable: At least 0.15 inches of rainfall in 30  
minutes and a flow stream level of more than 0.25 feet;  
once enabled, stay enabled, sample taken when the  
sampler is enabled.  
• Part ‘A’ pause and resumes: None.  
• Part ‘B’ pacing: Flow pacing, sampling every 2,500  
gallons.  
• Part ‘B’ distribution: Sequential, 1 sample per bottle.  
• Part ‘B’ sample volume: 500 milliliters.  
• Part ‘B’ enable: At least 0.15 inches of rainfall in 30  
minutes and a flow stream level of more than 0.25 feet;

5.7 Suction Head  
Suction head is the vertical distance between the surface of the  
liquid source and the sampler’s pump. At each sample event, the  
sampler determines the suction head automatically.  
Extended Screen for  
Suction Head Settings  
In extended programming, you can manually enter the suction  
head if you want. Select ENTER HEAD only when the head  
remains stable and you can measure it accurately.  
AUTO SUCTION HEAD  
ENTER HEAD  
If you choose AUTO SUCTION  
HEAD, the head will be

5.8 Rinses and Retries  
Rinses and retries are extended programming features. You can  
program the sampler to rinse the suction line automatically.  
During a line rinse cycle, the sampler draws liquid through the  
line to the liquid detector. As soon as it detects liquid, the  
sampler reverses the pump to purge the line.

in margin) has four items listed instead of two.  
“Uniform time” pacing is identical to “time” pacing in standard  
programming. “Flow paced” is the same for both types of pro-  
gramming. Event paced and nonuniform time pacing are  
described below.  
5.9.1 Event Pacing  
To program the sampler for event pacing, select event paced.  
Refer to Table 5-3 for an example of event paced sampling that  
uses three event conditions.  
Up to fourteen event conditions can be defined (for two-part pro-  
grams, up to fourteen event conditions can be defined for each  
part). An event will occur when any of the programmed event

Section 5 Extended Programming  
conditions becomes true. The default distribution setting for  
event-paced sampling is sequential (each time an event occurs,  
the sampler takes one sample, placing it in one bottle). However,  
any distribution setting may be used.  
If you have programmed multiple conditions, and more than one  
condition comes true at the same time (within your measurement  
interval), one sample will be taken and all conditions that caused  
the event will be noted on reports.  
Although you can combine flow pacing and all time pacing types  
with any distribution, event paced programs by definition use  
only sequential distribution. The sampler finishes an event  
paced program after depositing a sample in each bottle.  
Table 5-3 uses rate of change for the event condition (see step  
7). This feature enables the event condition under specific cir-  
cumstances.  
In the example below, a rate of change is set so that if the level  
rises more than one foot in a two hour time period, the event con-  
dition would be enabled and a sample taken.  
In determining if the rise occurs in this example, the sampler  
looks back at the previous two hour time period to see if there is  
a rise of more than one foot between any valley (low point) or  
peak (high point) within that time period.  
Once the condition becomes true (a rise of more than one foot is  
noted), the event condition is enabled. It will not be enabled  
again unless the condition becomes false, and then true again,  
within the two hour time window.  
In event pacing, up to three different rate of change event condi-  
tions can be programmed (for two-part programs, a total of six  
rate of change event conditions can be defined, three for each  
part).

This example uses a sampler with an attached 730 Bubbler Flow  
Module, Rain Gauge, and an SDI-12 sonde at address 5 with four

Section 5 Extended Programming  
5.9.3 Nonuniform Time  
Pacing  
The extended time pacing options are uniform time and non-  
uniform time. “Uniform time” pacing is identical to “time” pacing  
in standard programming. Nonuniform time pacing uses an  
irregular interval between sample events; each interval is indi-  
vidually programmable. There are three types of nonuniform  
time pacing:  
• Nonuniform clock time pacing.  
• Nonuniform interval pacing.  
• Random interval pacing.  
5.9.4 Nonuniform Clock  
Time Pacing  
For clock time pacing, enter specific times for each sample event  
(see screen 2). You can enter as many as 99 clock times, but the  
interval between times cannot be greater than 24 hours.  
(Remember to use a 24-hour clock when entering times.) The  
sampler takes a sample at the start time.  
5.9.5 Nonuniform Interval  
Pacing  
For nonuniform interval pacing, enter the number of sample  
events spaced at intervals of minutes: 12 samples at 5 minute  
intervals, 6 samples at 10 minute intervals, and so on. The  
sampler accepts as many as 99 nonuniform interval entries. The  
sampler takes a sample at start time.  
5.9.6 Random Interval  
Pacing  
To program the sampler for random interval pacing, enter the  
length of time you want to sample. The run time is the only  
random programming setting you’ll need to enter because the  
sampler derives the number of sample events required for the  
program from the distribution settings. (You can combine  
random pacing with any distribution.) Each time you run the  
program, the sampler generates a new set of random intervals.  
This makes each sample event unpredictable from run to run.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.10 Distribution  
Distribution describes how the sampler is to deposit samples. A  
sample is the volume of liquid deposited in a bottle. A sample  
event includes the full sampling cycle and may deposit a sample  
into more than one bottle. You can program the sampler for five  
distribution methods:  
• Sequential  
• Bottles per sample  
• Samples per bottle  
• Composite  
• Multiple Bottle Compositing  
5.10.1 Sequential  
In sequential distribution, the sampler deposits one sample in  
each bottle. A sequential sample represents a “snapshot” of the  
flow stream at a point in time.  
5.10.2 Bottles Per Sample  
In bottles per sample distribution, the sampler deposits a sample  
in each of a set of bottles. A bottle set includes at least two bottles  
but may include all bottles. Use bottles per sample when the  
volume to be collected is larger than the amount one bottle can  
hold or when you need identical samples.  
5.10.3 Samples Per Bottle  
5.10.4 Composite  
In samples per bottle distribution, the sampler deposits samples  
from several sample events in a single bottle before moving to the  
next bottle. Use samples per bottle distribution to collect a series  
of small composite samples.  
For single bottle configurations, samples per bottle distribution  
is known as composite sampling. A composite sample represents  
an average of the flow stream’s characteristics during the sam-  
pling period.  
5.10.5 Multiple Bottle  
Compositing  
Multiple bottle compositing is a combination of  
bottles-per-sample and samples-per-bottle. At each sample event,  
the sampler deposits a sample into a set of bottles. It moves to a  
new bottle set only after each bottle of the first set contains the  
programmed number of samples. Use multiple-bottle compos-  
iting to collect identical sets of composite samples or a composite  
sample that is larger than the capacity of a single bottle. Mul-  
tiple bottle compositing is available only in extended pro-  
gramming.  
5.10.6 Time Switching  
In extended programming, the sampler offers an additional dis-  
tribution feature, time switching. This feature determines when  
the sampler fills the next bottle or bottle set, and may be used  
with time-paced or flow-paced sample programs. Time switching  
distribution occurs at regular intervals (as programmed in  
screen 3 in the margin). The switch times are relative to the pro-  
grammed “FIRST SWITCH TIME” (screen 4).  
Switch times occur regardless of the state of the sampler. Be  
aware that the sampler may leave empty bottles if it becomes  
disabled. Pause and resumes are an exception; the sampler will  
not switch bottles during a pause if the current bottle is empty.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
If the program settings instruct the sampler to take a sample at  
the start time, the sampler also draws a sample at the switch  
time. When this occurs, the pacing will also be reset at the switch  
time.

Time switching is normally used with flow-paced programs that  
do not take a sample at start. These programs will place a  
sample in the current bottle if it is empty at the switch time, and  
then move to the next bottle/set. Pacing intervals are reset at  
every switch time.  
•Enter the number of bottles  
that should receive samples

• Enter the time between

• Enter the first bottle

5.10.7 Continuous Sampling  
Sample programs can be run indefinitely by selecting “YES” at  
the “RUN CONTINUOUSLY?” screen. Continuous sampling  
resets the distribution when the distribution sequence is com-  
plete. That is, when the last bottle/set is reached, the next  
bottle/set is the first bottle/set. All pacing modes except  
RANDOM are supported.  
When running a program continuously, the bottles must be ser-  
viced at regular intervals to prevent overfilling the bottles. The  
sampler assumes that the next bottle/set is empty and ready to  
receive samples. If you are using this feature with two-part pro-  
gramming, keep in mind that the parts will most likely reset at  
different intervals.

Section 5 Extended Programming  
5.11 Flow Proportional  
Sample Volumes  
The 6712 can collect flow proportional sample volumes. For some  
sampling protocols, these flow-weighted, variable-volume  
samples can be more representative of the stream. This is  
because stream characteristics often change as the flow fluc-  
tuates.  
Variable-volume sampling is possible when the sampler is pro-  
grammed for Uniform Time pacing. To enable this feature, select  
YES at the display asking “DO YOU WANT SAMPLE  
VOLUMES DEPENDENT ON FLOW?”  
DO YOU WANT  
SAMPLE VOLUMES  
DEPENDENT ON FLOW?  
YES  
NO  
After answering YES, the sampler displays screens to program  
the flow proportional volumes. If the sampler has a 700 Series  
Flow Module inserted, you will be asked which flow mea-  
surement should be used to determine the volumes.  
FLOW PULSES  
FLOW MODULE VOLUME  
To base the volumes on an external flow measurement device  
attached to the Flow Meter connector, select FLOW PULSES. To  
base the volumes on the 700 Series Flow Module readings, select  
FLOW MODULE VOLUME.  
Next, the sampler asks for the SAMPLE VOLUME to collect at  
each time interval. This volume is expressed as 10 ml for every X  
number of pulses, or if using a flow module, for every volume  
unit.  
SAMPLE VOLUME:

tings, for a more detailed discussion on this setting.  
The final screen used to program variable-volume sampling is  
the MINIMUM SAMPLE VOLUME. If the number of flow pulses  
or flow module volume is not sufficient enough to collect this  
minimum volume, the sample is skipped and the flow count  
carries over to the next sample time. This setting ranges from  
10 ml to a maximum determined by the bottle volume.

5.11.1 Calculating Variable  
Sample Volume  
Settings  
The entry for the SAMPLE VOLUME display can be calculated  
based on expected flow rates and collection volume requirements.  
The number of pulses or flow module volume that you enter  
should ensure that the minimum volume of liquid required for  
analysis is collected without exceeding the bottle volume capacity  
of the sampler. You may find it helpful to determine a range of  
values by calculating both possibilities. The number you enter  
would be selected from this range. This range is illustrated in  
Figure 5-2.

Figure 5-2 Factors Affecting Flow-Weighted Variable-Volume Samples  
In other words, at the greatest expected flow, this SAMPLE  
VOLUME value should be set to prevent filling the bottle before  
the end of the program. An early full-bottle condition would  
result in a composite sample that is not representative of the  
flow stream.  
At the lowest expected flow, the SAMPLE VOLUME value should  
be set to ensure that enough sample is collected. If too little  
sample liquid is collected, there may not be enough for analysis  
although it is a representative composite sample.  
For example, consider an NPDES sampling program used to  
collect a flow-proportional composite sample for BOD, TSS, and  
NH -N analysis. The laboratory requires at least 1,000 ml for  
3
BOD, 100 ml for TSS, and 400 ml for NH -N tests. The minimum  
3
composite volume needed for analysis is then 1,500 ml, but to  
allow for duplicates and spillage, this volume is doubled to  
3,000 ml. The samples are to be collected over an eight hour  
period at 15 minute intervals into a 9,400 ml composite bottle.  
Flow rates at the site range from 1.5 to 2.0 mgd, the equivalent  
volume of 500,000 and 666,667 gallons respectively over the  
eight hour period. This flow is measured by an external flow  
meter that sends a flow pulse every 100 gallons. Figure 5-3  
depicts this scenario.

Figure 5-3 Variable-Volume Scenario  
5.11.2 Calculations when  
The highest possible SAMPLE VOLUME value is determined by  
Using an External Flow the minimum volume required for analysis and the least  
Meter  
expected flow rate over the sampling duration. To calculate the  
number of pulses at this high end of the range, you should know:  
• the least expected flow volume that will pass the flow  
measurement point  
SAMPLE VOLUME:  
10 ml FOR EVERY  
___ PULSES  
• the flow volume interval between each flow pulse from  
the external flow meter  
• the minimum composite sample volume required for  
analysis. Allow for duplicates and spillage.  
These factors would be applied to the following equation.  
(Least Total Flow Vol) / (Flow Pulse Vol)  
=
10 ml for every __ pulses  
(Minimum Required Vol) / (10 ml per unit)  
From the scenario we can apply the factors for the equation.  
(500,000 gallons) / (100 gallons per pulse)  
=
10 ml for every 16.7 pulses  
(3,000 ml / 10 ml)  
Because the SAMPLE VOLUME entry must be in whole  
numbers, 16.7 is rounded down to 16. It is important to note that  
this number is inversely proportional to the amount of volume  
collected. Rounding up would result in less volume collected.  
The lowest possible SAMPLE VOLUME value is dependent upon  
the highest expected flow and the available bottle volume. To cal-  
culate the number of pulses or volume at this low end, you should  
know:  
• the greatest expected flow volume that will pass the flow  
measurement point  
• the flow volume interval between each flow pulse from  
an external flow meter  
• the available bottle volume for sample collection.

These factors would be applied to the following equation.  
(Greatest Total Flow Vol) / (Flow Pulse Vol)  
=
10 ml for every __ pulses  
(Total Bottle Vol) / (10 ml per unit)  
From the scenario we can apply the factors to the equation.  
(666,667 gallons / 100 gallons)  
=
10 ml for every 7.0 pulses  
(9,400 ml / 10 ml)  
At high flow rates, a number below 7 would overfill the bottle. At  
low flow rates, a number greater than 16 would collect too little  
sample. Therefore, a value should be selected between 7 and 16  
pulses.  
5.11.3 Calculations when  
The same principles discussed in Section 5.11.2 apply. However,  
Using a 700 Series Flow the equations differ slightly because the flow module directly  
Module  
measures the stream’s flow volumes. The equation for the high  
end of the range is:  
(Least Total Flow Vol)  
=
10 ml for every __ units  
(Minimum Required Vol) / (10 ml per unit)  
Using the same scenario the calculations would be:  
SAMPLE VOLUME:  
10 ml FOR EVERY  
___ Gallons  
500,000 gallons  
=
10 ml for every 1667 gallons  
(3,000 ml) / (10 ml per gallon)  
The equation for the low end of the range is:  
(Greatest Total Flow Vol)  
(Total Bottle Vol) / (10 ml per unit)  
=
10 ml for every __ units  
The scenario would be applied as:  
666,667 gallons  
=
10 ml for every 709 gallons  
(9400 ml) / (10 ml per unit)  
Therefore, a value should be selected between 709 and 1667  
gallons for the given scenario.  
5.12 Sampler Enable  
Certain external instruments can enable (start) or disable (stop)  
a sampler by sending a signal to pin F of the sampler’s flow  
meter connector. Teledyne Isco flow meters, flow loggers, and the  
Teledyne Isco 1640 Liquid Level Actuator have a programmable  
sampler-enable feature that lets them enable or disable the  
sampler. You can define the condition (such as level, flow rate,  
pH, temperature, percent, rainfall, and I/O) or combination of  
conditions that need to be true in order to enable the sampler.  
Refer to Figure A-12 in Appendix A for details on programming  
sampler enables.

When the sampler detects that it is disabled at start time, it sus-  
pends the program until it is enabled. Once enabled, the sampler  
collects a sample only when programmed to take a sample at the

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.13 Sampler Enable  
Responses  
In addition to programming enable conditions, extended pro-  
gramming lets you control the sampler’s response to its enable  
state. You can:  
• Stay enabled after the first enable.  
• Set up a repeatable enable.  
• Take a sample at enable or disable.  
• Delay the start of sampling after the enable.  
• Reset the sampling interval countdown each time the  
sampler is enabled.  
• Control the sampling interval countdown while  
disabled.  
• Enable Part B of a two-part program when Part A is  
done.  
5.13.1 Once Enabled Stay  
Enabled  
For certain monitoring programs, you may want the sampler to  
continue to sample, even though the conditions that enabled the  
sampler no longer exist. When you use the ONCE ENABLED,  
STAY ENABLED feature, after becoming enabled the sampler  
takes samples until it reaches the end of its program.  
ONCE ENABLED,  
STAY ENABLED?  
YES NO  
Note  
The STAY ENABLED feature works only when the sampler  
becomes enabled following program start. If you need this fea-  
ture with enable prior to program start, contact Teledyne Isco  
for details.  
5.13.2 Repeatable Enable  
After enabling the sampler, the enabling instrument (or instru-  
ments) continues to monitor the conditions and disables the  
sampler when the conditions are no longer satisfied. If  
re-enabled, the sampler resumes the sampling program.  
Note  
Repeatable enable is called “sampler latching” in flow meters,  
flow loggers, and FLOWLINK. Latching a sampler produces  
the same results as selecting YES; the difference is that the  
external instrument controls the latching.  
5.13.3 Sample at Enable or  
Disable  
You have the option of directing the sampler to take a sample as  
soon as it receives the enable and/or disable signal. If you  
program the sampler to stay enabled and choose to take a sample  
at enable, the sample interval will be reset at the enable time.  
Samples at disable do not affect the sample intervals. Standard  
programs do not take a sample at the enable time.  
SAMPLE AT ENABLE?  
YES NO

5.13.4 Delay To Start Of  
Sampling  
If you have selected ONCE ENABLED STAY ENABLED and  
have chosen to not sample at the enable, you have the oppor-  
tunity to suspend the start of sampling. This choice is useful for  
storm programs that require a flow-paced sample taken after the  
initial grab sample.  
START SAMPLING  
AFTER A  
___ MINUTE DELAY  
(1-999)  
5.13.5 “Dry Period” Option  
For samplers used with a 0.01 inch tip rain gauge, you can cause  
the sampler to wait for a “dry” period of under 0.10 inches of rain  
over a 72-hour period before running the program. At RUN time,  
the sampler asks if you want to restart the 72-hour period. Select  
this choice if you want the sampler to disregard any “dry” period  
that took place prior to the program start. The sampler will wait  
for up to one year for the “dry” period to occur.  
START “EXTENDED 1”  
AFTER A 72 HOUR  
“DRY” PERIOD?  
YES NO  
5.13.6 Resetting the Sample  
Interval at Enable  
You may want the pacing countdown to start over each time the  
sampler becomes enabled. To accomplish this, select “YES” when  
asked if you want to reset the sample interval at enable. The next  
sample event will occur at the end of a full interval. Fur-  
thermore, if the sampler is enabled several times during the  
program, it resets the countdown each time.  
RESET SAMPLE  
INTERVAL AT ENABLE?  
YES NO  
If you answer “NO” to the above  
screen, you will see:  
Use the reset-interval feature carefully. For example, avoid  
resetting the interval when you sample with uniform-time  
pacing and want to take samples at specific times.  
CONTINUE COUNTDOWN  
WHILE DISABLED?  
YES NO  
The effects of resetting the interval can be seen in this example:  
A sampler has been programmed to sample every 15 minutes and  
to reset the interval when enabled. It receives an enable signal at  
10:03 and takes a sample. After resetting the interval, the  
sampler takes subsequent samples at 10:18 (not 10:15), 10:33  
(not 10:30), and so on.  
If you select “NO” when asked if you want to reset the sample  
interval at enable, you will be asked if you want to continue the  
countdown while disabled. You can have the sampler continue  
the countdown, repeating it as often as necessary while the  
sampler is disabled, or you may suspend the countdown while  
disabled, resuming the countdown as the sampler is enabled. The  
standard program allows the countdown to continue while dis-  
abled.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.14 Pauses/Resumes  
Pause and resume settings, available in extended programming,  
create an intermittent sampling schedule. A program with  
pauses and resumes begins sampling at its programmed start  
time, continuing until the first pause time and day of the week. It  
then suspends sampling until the first resume time, when it  
begins sampling again. If the start time falls within a pause  
period, the sampler will not begin sampling until the next  
resume time. Pauses and resumes repeat weekly.  
Pause and Resume Screens  
Flowcharts containing the pause and  
resume screen appear in Appendix  
A.  
PAUSE  
RESUME  
1. 17:00 MO 08:00 TU  
2. 17:00 TU 08:00 WE  
CLEAR  
DONE  
You can enter up to nine pairs of pause and resume times. The  
pause and resume times shown as examples to the left suspend  
the program between 5:00 p.m. Monday and 8:00 a.m. on  
Tuesday and between 5:00 p.m. Tuesday and 8:00 a.m. on  
Wednesday. If the start time is Monday at 8:00 a.m., the sampler  
takes samples between 8:00 a.m. and 5:00 p.m. Monday; between  
8:00 a.m. and 5:00 p.m. Tuesday; and, continues after 8:00 a.m.  
Wednesday. To remove pause and resume settings from a  
program, select CLEAR.  
SAMPLE AT RESUME?  
YES NO  
A sampler running a pause/resume program resets the pacing  
interval at each resume time. You can program the sampler to  
take a sample at resume times (see screen at left).  
5.15 Running Programs  
To run an extended program, select run from the main menu.  
You may also select YES at the RUN THIS PROGRAM NOW?  
screen at the end of the programming screens.  
Extended programs scheduled to start at a clock time will not  
start until the programmed clock time on or after the first valid  
date.  
Note that if you have recently calibrated a parameter probe, the  
sampler may delay the start and display “PLEASE WAIT” until  
valid readings are expected from the probe. The delay accounts  
for the time typically required to install the probe, and lasts for  
five minutes after you complete the calibration.  
5.15.1 Run Time Screens  
Run time screens, which report the program’s status while  
running a program, are explained in Section 4.  
5.15.2 Interrupting a  
Running Program  
Interrupting a running program is also explained in Section 4.  
The scrolling menu that appears during the manual paused state  
can have two extra options when using extended programming:  
Adjust Enable – This option is available for extended sampling  
programs that have programmed enable conditions. Selecting  
this option allows you to change the set-points or ranges for the  
enable conditions. The sampler displays all of the programming  
screens that define the thresholds of the programmed enables.  
You cannot change the type of enables used or the way they are  
combined.  
If rain is an enabling condition, you also have the option of  
resetting the rain history.

Adjust Suction Head – If you have chosen to manually enter  
the suction head, and are in the manual paused state, the  
scrolling menu will have an option to adjust the suction head. If  
you make changes to the suction head value, the sampler logs a  
changed suction head event.  
5.16 Sampling Reports  
The 6712 records a variety of data while running a sampling  
program. Sample reports can be found in Section 4.  
Section 4, Table 4-3 contains a list of source codes and program  
events that may be recorded when using either standard or  
extended programming.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
5.18.2 Programming Style  
The sampler has two different styles of programming screens:  
normal and quick view. These are both explained in Section 3.  
When you are in extended programming, the default style is  
Quick View, which allows you to move more quickly through the  
screens.  
If you prefer a step-by-step display for the screens, switch to the  
Normal setting.  
5.18.3 Measurement Interval  
If using a 700 Series module or SDI-12 Sonde parameter for  
enabling, the sampler will request a Measurement Interval. The  
Measurement Interval allows the sampler to compare the  
parameter to the enabling conditions at a rate faster than the  
Data Storage interval. If the Measurement Interval is equal to or  
greater than the Data Storage interval, the parameter will be  
checked at the rate of Data Storage interval.  
MEASUREMENT INTERVAL  
5

15 30 SECONDS

MINUTES  
STORAGE INTERVAL  
Normally, there are two considerations when selecting the Mea-  
surement Interval: power consumption and duration of the  
enabling event. This setting for battery powered samplers will  
require some degree of balance between the need to conserve  
power yet detect the enabling event before it has passed.  
5.18.4 Dual Sampler Mode  
Dual Sampler Mode lets you operate two samplers as a pair. The  
primary sampler disables the secondary one until the primary  
sampler completes its sampling program. The samplers then  
reverse roles with the second sampler becoming the primary one.  
Dual Sampler Mode  
DUAL SAMPLER MODE?  
YES NO  
Setting Up Dual Samplers –  
1. Turn on the dual sampler mode in both samplers.  
2. Install the samplers.  
• Select YES to put the sampler  
in the dual sampler mode.  
When you no longer need  
dual samplers, return to this  
screen to turn the feature off.  
3. Connect the samplers with the Dual Sampler Mode Inter-  
connect Cable by attaching the cable to the sampler’s  
flow-meter connectors. If your installation includes a flow  
meter or flow logger, use the Dual Sampler Mode to Flow  
Meter Cable instead.  
4. Decide which sampler is to be the primary sampler; the  
primary sampler should be the sampler with the program  
you want to run first.  
5. Turn the primary sampler on and run its sampling pro-  
gram by selecting RUN. After at least 5 seconds, turn the  
secondary sampler on and select RUN from its main menu.  
How Does It Work? – The primary sampler sends a disable  
signal out its flow meter connector. The secondary sampler  
receiving the signal is held disabled until the primary sampler  
completes its program.  
When using a flow meter or flow logger a Dual Sampler Mode to  
Flow Meter cable must be used. This cable is constructed so that  
the pacing instrument receives only the event marks. Therefore,  
a connected flow meter will not receive a bottle number signal,  
nor will it be able to control the sampler inhibit.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
Bottle Full Detection – The sampler can detect a full bottle  
condition when collecting samples in a single bottle (composite  
sampling). When the sampler detects a full bottle, it stops the  
sampling routine.  
Bottle Full Detect  
BOTTLE FULL DETECT?  
YES  
NO  
A BOTTLE FULL condition will also stop a sampling routine  
that is set to RUN CONTINUOUSLY.  
The Bottle Full Detect screen allows you to enable or disable this  
feature. Selecting “YES” enables the sampler to detect a full  
bottle and stop the sampling routine. Selecting “NO” disables  
this feature. The Bottle Full Detect setting is part of the sam-  
pling program. Because it is a program setting, full bottle  
detection can be enabled or disabled for each of the four extended  
programs. If the Bottle Full Detect setting is critical to your sam-  
pling program, always check this Software setting after you  
select a different Extended Program.  
This feature relies on a post-purge after each sample. When  
using the Bottle Full Detect, make sure that post-sample purges  
greater than 100 are used.  
Bottle Full Detect is always disabled in the Standard Pro-  
gramming mode.  
Display Backlighting – The display has a backlight that is  
adjustable so that the backlight is always off, timed or always on.  
Adjusting the Display  
Backlighting  
In the timed backlight mode the sampler turns the backlight off  
after detecting no key strokes within 60 seconds. Any keystroke  
(except ON-OFF) turns the backlighting on again. In this mode  
the backlight must be on before the sampler accepts a menu  
choice or number entry. If you press a key and a screen does not  
respond, it is because the keystroke turned the backlight on.  
BACKLIGHT ALWAYS OFF  
TIMED BACKLIGHT  
CONTINUOUS BACKLIGHT  
It is recommended that you use either BACKLIGHT ALWAYS  
OFF or TIMED BACKLIGHT when using a battery.  
Event Marks – The sampler generates an event mark at each  
sample event, sending it through the flow meter connector to a  
connected instrument. The event mark may also control an  
external device; a connected solenoid relay, for example. When  
using the event mark for a data logger or to control external  
devices, you may need to adjust the mark by changing the factory  
settings.  
Event Marks  
EVENT MARK SENT FOR:  
EVERY SAMPLE  
COMPLETE SAMPLES  
The event mark is adjustable through the software setup screens.  
You can set up the sampler to generate an event mark for  
EVERY SAMPLE or for COMPLETE SAMPLES.  
If you select COMPLETE SAMPLES, the sampler sends a  
three-second pulse only after it successfully collects a sample.  
The sampler will not send an event mark if an error occurs, such  
as “No Liquid Detected.”  
If you select EVERY SAMPLE, the sampler will send an event  
mark every time a sample is initiated. The event mark signal can  
be a:  
• 3-second pulse at the beginning of the pre-sample purge.

only, marking the time the sampler deposited the  
sample.  
• Variable duration pulse generated during the pump  
cycle, from the beginning of the pre-sample purge to the  
end of the postsample purge.  
• Variable duration pulse generated only during forward  
pumping.  
Figure 5-5 shows event mark timing diagrams.  
Bottle Number – Concurrent with the event mark, the sampler  
also sends a bottle number signal. The bottle number signal is a  
series of pulses. The number of pulses sent represents the bottle  
currently accepting a sample (see Figure 5-5).

5.18.5 Pre-sample and  
Post-sample Purge  
Counts  
The pre-sample purge is when the pump runs in reverse clearing  
the strainer of any debris before taking a sample. The pre-sample  
purge is set at 200 pump counts. After the sample is taken a  
post-sample purge occurs to clear the liquid from the suction line.  
The duration of the post-sample purge is determined by the  
length of the suction line to maximize the battery life. The pre-  
and post-sample purge can also be manually set.

5.18.7 Program Lock  
The specialized software option Program Lock (P/N 60-9003-532)  
may be purchased from Teledyne Isco.  
Once activated, the purchased option is always available, even if  
the software is upgraded at a later time. The option must be  
installed at the factory. Consult the factory for further  
details.  
To view which software options have been activated, select VIEW  
REPORT>SYSTEM IDs. A software options screen will list a  
code for each active option. The code for Program Lock is 1108.  
PROGRAM LOCK DISABLED  
The Program Lock adds password security to the 6712 sampling  
programs. With this option activated, a user-selected password  
(up to five digits) must be entered before any program changes or  
run time modifications can be made. Run time modifications  
include accessing the Manual Pause menu options and shutting  
off the sampler. You will still be able to run the current program,  
view reports, and interrogate the sampler without the knowledge  
of the password.  
ENABLE PROGRAM LOCK?  
YES NO  
If three consecutive attempts to enter the password fail, a five  
minute “time-out” will follow in which most keys are deactivated.  
CHANGE PASSWORD TO  
----------  
The user-selected password defaults to “6712” and may be  
changed in the Software options that are available in the  
Extended Program mode (see example at left). While the  
password may only be changed in the Extended Program mode,  
the program lock works for both Standard and Extended pro-  
grams.  
REENTER NEW PASSWORD  
---------  
Should you forget your password, a key code can be obtained  
from Teledyne Isco’s Customer Support department for a  
nominal fee.

5.19.2 Rain Gauge Setup  
The 6712 supports SDI-12 sondes. For more information on  
setting up sondes, refer to Section 6.  
With standard programming, the sampler does not record rain  
gauge readings. However, with extended programming, recording  
the rain gauge readings and the rain enable option can be turned  
on or off. Enter the hardware setup and follow the screens to the  
left in the margin.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
When asked if you have a rain gauge connected, select YES to  
record the rain gauge readings and add RAIN as a sampler  
enable option. Select the appropriate tip for the rain gauge. The  
sampler will then create a rain memory partition and update the  
available sampler enable conditions.  
DO YOU HAVE A  
RAIN GAuGE CONNECTED?  
YES NO  
• Select YES.  
Select NO to disable the readings and the sampler enable option.  
When you select NO, the sampler removes the rain memory par-  
tition, leaving the memory space available for other reading  
types.  
RAIN GAUGE:  
0.01 inch TIP  
0.1 mm TIP  
• The rain gauges are set up to  
tip on either .01 inch or .1 mm.  
Select the desired tip.  
5.19.3 I/O Pin Programming  
Pins C, H, and I on the Rain Gauge Connector are user-con-  
figured as I/O1, I/O2, and I/O3 (Input/Output pins) respectively.  
Each pin can be either an input for sampler enabling, or an  
output for alarms.  
Note  
The state of the I/O lines is not defined when the sampler is  
OFF.  
The enable input requires a pulse signal of 5 to 15 volts. Teledyne  
Isco offers optional interface modules for converting from a 4-20  
mA analog or pulse duration signal.  
The alarm output can be set for any RUNNING PROGRAM or  
RUN ERROR state. In addition, the CONDITIONS output can  
report alarm conditions using the parameters the 6712 is con-  
figured to measure. You can set thresholds for one or two condi-  
tions and the CONDITIONS output can then trigger alarms  
when the measured parameters exceed the threshold.  
The alarm output requires an alarm interface module. Teledyne  
Isco offers a module designed to provide one, two, or three  
contact closures. The alarm module can interface the sampler  
with a large number of non-Teledyne Isco devices. For more infor-  
mation about the alarm module, contact your Teledyne Isco sales  
representative.  
5.19.4 Refrigerator  
Temperature  
Teledyne Isco offers a temperature sensor intended for use with  
the 6712FR Refrigerated Sampler. The optional sensor connects  
to the Rain Gauge port and uses I/O3 to transmit its temperature  
readings to the 6712.  
Note  
If alarms are being used, the temperature sensor is simply  
plugged into the panel mount on the one- or two-alarm output  
module. Because the temperature sensor uses I/O3, it cannot  
be used with a three-alarm output module.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
To configure an attached temperature sensor, select “FR-TEMP”  
as the input for I/O3. The 6712 will display the NEW  
HARDWARE SETUP screen. Select DONE and the 6712 recon-  
figures its memory partitions to record the temperature  
readings.  
Temperature readings are updated approximately every 2.5  
seconds. The readings are stored as FR-TEMP readings at the  
data storage interval. You can retrieve a history of temperature  
readings through the 6712’s reports. The temperature data also  
can be used as a sampler enable condition.  
5.19.5 Analog Output  
Teledyne Isco offers multiple analog outputs as a factory  
installed option. The number of isolated outputs can vary from  
one to three and is specified at order time. The option is installed  
inside the controller and includes a six-pin connector to interface  
with external devices.  
The analog outputs can be programmed for either 0-to-20 mA or  
4-to-20 mA operation. With the exception of rain, any parameter  
that the 6712 sampler is currently measuring can be used to  
control any (or all) of the analog output channels. Programming  
the outputs requires parameter levels at each end of the analog  
range and then assumes a linear relationship between those  
points. MANUAL CONTROL of each output is also available.  
Flowcharts for analog output screens appear in Appendix A.  
5.19.6 Dialout Alarms  
Dialout alarms require the sampler to be equipped with the  
factory-installed 2400 baud talking modem. The dialout alarm  
allows the sampler to notify a contact list when an “alarm” con-  
dition exists (is true).  
At the transition to the true state, any programmed I/O output  
can cause the sampler to warn of the alarm condition. As many  
as three telephone numbers can be entered. The sampler tries  
each telephone number in succession until the alarm is acknowl-  
edged. For each alarm condition, the sampler will attempt each  
telephone number entered a maximum of five times, at user spec-  
ified intervals.

Extended characters, the Comma (,), Pound (#), and Star (*), also  
may be included in the 25 digits. To enter an extended character,  
press the Decimal Point key on the Avalanche keypad. The Ava-  
lanche displays a screen used to select and enter the extended  
characters. Each comma entered will cause the modem to pause  
for two seconds before proceeding with the remaining digits.  
Phone numbers that are no longer needed can be removed.  
Advance the cursor to the end of the telephone number and then  
press the Left Arrow key to erase the preceding character. If the  
cursor is not at the end of the telephone number, the Left Arrow  
key will only shift the cursor without erasing any characters.  
Dialout telephone and pager numbers are included in the  
Program Settings Report.  
Note  
Connecting either the serial output or the standard interrogator  
cable to the Avalanche disables the internal dial-out modem.  
The interrogator or serial output cable must be disconnected  
before you can use the modem.  
5.19.7 Pager Numbers  
The extended character screen contains a pager option that des-  
ignates the phone number as a pager. When programmed as a  
pager number, an identification string will be sent seven times  
after the pager number is dialed, with a three second delay  
between strings.  
An example identification string would be “828-1”, meaning  
“Alarm condition #1 exists at sampler 828”. If more than one  
alarm condition exists, the string would read similar to “828-1-3.  
5.19.8 Digital Modem Text  
Messaging  
The sampler can also send alarms in the form of text messages  
containing the same information as that found in voice messages.  
To use this option, you must have:  
• a cellular phone with text messaging capabilities  
• an external digital modem  
recommended: Teledyne Isco’s AnyDATA modem  
part # 60-5314-489  
Note  
If an internal voice modem is installed, the sampler will use  
that modem, and text messaging will be disabled.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
When you enter each of the (up to three) phone numbers for the  
sampler to call, if text messaging is active, a request for the TAP  
(Telocator Alphanumeric Protocol) server number and communi-  
cations parameters will be made.  
As with voice messaging, the sampler will dial each telephone  
number up to five times per alarm condition, until the message is  
acknowledged.  
5.20 Memory  
The 6712 Sampler contains 512 kilobytes of battery backed RAM  
(Random Access Memory) that stores:  
• Five sampling programs  
• The sampling results from the most recent program  
• The rainfall data collected from rain gauges  
• The data from a refrigerator temperature sensor  
• The data collected from a 700 Series module  
• Parameter data collected from an SDI-12 Sonde  
• Calculated flow information from the current flow  
module  
The sampling results memory stores up to approximately 1004  
events (the actual number is dependent on the number of SDI-12  
parameters). The program run and start time information is  
logged as four events. These four entries are held for the duration  
of the program. The remaining 1000 are for logging sample  
events, program events, and errors from the currently running  
program. If the running program exceeds 1000 events, the data  
will “roll over.” That is, the sampler will replace the oldest stored  
event with the newest event. When using an SDI-12 sonde, the  
sampler logs additional entries at each sample event.  
Module, sonde, refrigerator temperature, and rain gauge  
readings are stored in memory partitions. The storage capacity  
depends on the reading types, the number of bytes per reading,  
and the data storage interval.  
The sampler clears the sampling results memory when the site  
description changes. It is important to collect the sampling  
results before changing the site description – the data can not be  
retrieved afterwards. Keep in mind that the description may  
change when selecting an extended program.  
The partition data is cleared when the sampler automatically  
creates and sizes the memory partitions. This occurs when you:  
• Select a new program with a different storage interval  
• Change the Data Storage Interval in the current  
program  
• Change the programming mode  
• Install a new 700 Series Module  
• Change 700 Series Module mode of operation  
• Add or remove a rain gauge with the Hardware Setup  
• Add or remove a refrigerator temperature sensor as I/O3

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
• Add or remove a SDI-12 sonde parameter with the  
Hardware Setup  
• Reinitialize the sampler  
The stored data is lost as the sampler reformats its memory. As a  
precaution, before clearing the memory, the sampler display will  
show the following message:  
INTERVAL CHANGED --  
DOWNLOAD DATA NOW  
OR LOSE ALL DATA!  
DONE  
If you want to keep the stored data, download it before pro-  
ceeding. When DONE is selected, the sampler clears the stored  
data and reformats the memory partitions. The sampler then dis-  
plays the new capacity of the partition memory.  
PARTITION MEMORY  
WILL LAST 13 DAYS  
If the duration is too short, try changing the data storage  
interval or eliminating unnecessary reading types in the  
Hardware or Module Setup. For example, a sampler configured  
with a 730 Bubbler Module and a rain gauge storing data at a  
one-minute interval, creates level and rainfall partitions that  
hold 100 days of readings. Changing the storage interval to two  
minutes extends the storage capacity to 201 days.  
The sampler does not have to be running a program to store  
readings. When the sampler is on, it stores readings at the  
selected data storage interval. Once the partition is filled, the  
readings roll over.  
When the sampler is running a program, the partitions become  
“triggered” by the programmed start time or the first enable  
time, whichever is later. A triggered partition continues to log  
readings at the selected interval, but will not replace any  
readings taken after the trigger event. The sampler fills the par-  
tition and then stops recording to preserve the data. The first  
reading preserved in a full partition is one hour before the  
trigger event. A full partition can be reset by starting another  
program or changing storage parameters.  
If you need continuous readings for analysis, be sure to collect  
the readings before the partition fills or rolls over to avoid gaps  
in the data.  
5.21 Pressurized Lines  
The sampler can obtain samples from pressurized lines, as long  
as the line pressure remains below 15 PSI (pounds per square  
inch). Pressures greater than 15 PSI may prevent the sampler  
from purging the suction line; moreover, extreme pressures can  
force liquid past the pump, even when the pump is not running.

6712SR Refrigerated Sampler  
Section 5 Extended Programming  
For more consistent sample volumes from lines under constant  
pressure, calibrate the samples. Teledyne Isco does not rec-  
ommend sampling from pressurized lines.  
5.22 Command Driven  
Operation  
The 6712 controller can be used as a slave to an external con-  
troller. The external controller is responsible for determining  
when to take a sample, how much volume to pump, and where to  
put the sample. The external controller directly interfaces to the  
sampler via an RS-232 communications port at 2,400-19,200  
baud, 8 data bits, no parity, and 1 stop bit. A comma-sepa-  
rated-value protocol is used by the external controller to make  
requests, and by the sampler to report results. Use a standard  
computer connect cable (see Appendix E) to connect the sampler’s  
interrogator port and the external controller.  
For information on serial data codes and their meanings, refer to  
Table 5-5 Serial Data Codes in this section.  
The 6712 Sampler will respond to three commands: Turn  
Sampler On, GET STATUS, and TAKE SAMPLE. All commands  
must include the instruction set. The checksum value is optional.  
The available commands are:  
1. Turn Sampler On: STS,2,CS,582<CR>  
• “582” is the byte-by-byte sum of the ASCII values in the  
string “STS, 1,CS”.  
• “<CR>” is a carriage return signifying the end of the  
command.  
• If the sampler is OFF, this command will turn it ON  
before returning status info.  
2. Get Status: STS,1,CS,581<CR>  
“STS,1” instructs the sampler to return the current status.  
• “CS,581” is the optional checksum value. The  
byte-by-byte sum of the ASCII values in the string  
“STS,1,CS” is 581.  
• “<CR>” is a carriage return signifying the end of the  
command.  
3. Take Sample: BTL,2,SVO,100,CS,1039<CR>  
The TAKE SAMPLE command is only valid if the sampler is  
WAITING TO SAMPLE.  
• “BTL,2” instructs the sampler to place the sample in  
bottle 2.  
• “SVO,100” instructs the sampler to take a 100 ml  
sample.  
• “CS,1039” is the optional checksum value. The  
byte-by-byte sum of the ASCII values in the string  
“BTL,2,SVO,100,CS,” is 1039.  
• “<CR>” is a carriage return signifying the end of the  
command.

6712SR Refrigerated Sampler  
Section 6 SDI-12 Sondes  
In order to provide you with the flexibility to use the water  
parameter sensors that best meet your needs, Teledyne Isco has  
implemented support for SDI-12 protocol. Support of this  
standard allows you to use SDI-12 compatible devices in con-  
junction with your 6712SR sampler in Extended Programming  
mode.  
6.1 SDI-12 Data  
Parameters  
The 6712 Sampler can accept up to 16 parameters from up to ten  
sensors with SDI-12 addresses from 0 - 9 (refer to chart in Figure  
6-1). This data can be used in different ways. Data can be logged  
at user selectable time intervals for later download and pro-  
cessing by Teledyne Isco’s Flowlink™ program. You can set up  
sampling programs that will be enabled to run only if conditions  
based on parameters monitored by the connected SDI-12 devices  
are met. The sampler can also be programmed to take samples  
each time certain parameter limits are exceeded.  
The data parameters used by the sensing device (sonde) and  
recording device (sampler) must match. Otherwise, the  
equipment could record the data values for one parameter as  
another’s, such as reporting a pH value as being temperature.  
Certain vendors’ sondes (such as Hydrolab and YSI) have  
enhanced commands that facilitate “plug and play” setup. These  
Teledyne Isco Ready sondes can tell the 6712 what values they  
have, their order, and units of measure.  
Other SDI-12 compatible sondes can be used, but require manual  
setup to identify proper data types for each data value reported.  
This section shows you how to set up both Teledyne Isco Ready  
and other SDI-12 sondes for use with the 6712.  
WARNING  
SDI-12 Sondes have not been approved for use in  
hazardous locations as defined by the National Electrical  
Code.  
CAUTION  
Before you install any sonde, you must take the proper safety  
precautions. Refer to Appendix C in the back of this manual.  
Additional safety considerations may be required. Check appli-  
cable guidelines, codes, and regulations of federal, state, city,  
and county agencies.

6.2 Scanning For Sondes  
You must be in Extended Programming to use a sonde with the  
6712. The sampler can automatically scan for the presence of  
sondes if you enable that option:  
• From the main menu, select OTHER FUNCTIONS.  
• Select HARDWARE.  
• As you press to move through the hardware screens,  
you will see one that looks like the following:  
NO SDI-12 SONDE  
AUTO SDI-12 SCAN OFF  
Select “NO SDI-12 SONDE” to scan for sondes. If one is found,  
you can set it up, and the “AUTO SDI-12 SCAN” option will be  
switched to yes.  
Select the “AUTO SDI-12 SCAN” option to manually turn on (or  
off) automatic scanning for sondes when the sampler is turned  
on.  
If a sonde has already been connected and set up, the hardware  
screen will instead display a screen similar to the following:

6.4 Other SDI-12 Sondes  
If you have connected an SDI-12 sonde that is not Teledyne Isco  
Ready, you will need to define the sonde’s data values.  
When you select the address of the sonde you want to set up (see  
screens in the margin), the company model and other infor-  
mation will be displayed along with the number of data values

6.5 Sonde Setup - Storing  
Parameter Data  
Whether you are using a teledyne Isco Ready sonde or other  
SDI-12 compatible sonde, you will need to tell the 6712 if you  
want to store all of the parameter data or data from selected  
parameters.  
Data is stored in memory partitions. A fixed amount of memory  
is available to store data. If you are using some parameters to  
simply trigger an event or enable condition, it is not necessary to  
store the data.  
If all of the parameters’ data will fit in memory, you will be asked  
if you want to store all of the parameter data. Answering “NO”  
will still allow you to selectively store parameter data; otherwise,  
all data will be stored.  
You will be asked to store parameter data during the setup  
process. You can also manually change the setup using options in  
the Hardware menu.  
To access the setup option in the Hardware menu, select Other  
Function from the main menu, then choose Hardware. Advance  
through the screens until you see one that displays SDI-12  
DATA.

Select this screen to display the following:  
NO SDI-12 SONDE  
SETUP KNOWN SONDES  
SCAN SDI-12 SONDES  
Select “SETUP KNOWN SONDES” and then indicate the  
address of the sonde you want to setup. A screen containing the  
sonde model and number of data values will appear briefly. Then  
you will be asked to verify, parameter by parameter, what data  
you want to store. The screens will look similar to the one below:  
SONDE 5, STORE  
TEMPERATURE DATA?  
YES NO  
LABEL IS: TEMP5  
Indicate if you want to store the data for that particular  
parameter and then advance through the rest of the parameter  
screens. Once you have defined your data storage options, select  
“DONE.”  
You will be prompted that you have entered a new hardware  
setup and asked if you want to erase the stored data. Indicate  
“YES” or “NO.” A partition memory status message will be dis-  
played and (if a parameter exists that can be calibrated) you will  
then advance to the calibration screen (refer to “SONDE CALI-  
BRATION AND VALIDATION” on this page). If you do not want  
to calibrate or validate, select “DONE” to return to the Hardware  
Options screens.  
6.6 Sonde Calibration and It is recommended that calibration of your sonde be done  
in the lab, according to manufacturer’s recommendations.  
Validation  
However, for your convenience, the 6712 allows for field cali-  
bration of pH, Dissolved Oxygen (DO), and Oxidation Reduction  
Potential (ORP).  
Field calibrations are stored in the sampler, NOT the sonde, and  
are used to modify readings from the sonde until a new sonde is  
connected. When a sonde is moved to another sampler, it will  
retain calibration constants set in the lab, but will not retain any  
that were set in the field.  
Although field calibration is limited to three parameters, you can  
validate any of the available parameters. Validation allows you  
to immerse the sonde in a known solution, note the readings, and  
see if the sonde is functioning properly. The validation process  
does not modify any readings like calibration does; it merely  
alerts you to inaccurate ones.  
No data will be stored, nor will enable conditions be updated,  
while calibrations or validations are being performed.

The sonde’s address will appear after the parameter (such as  
pH0 and pH5). If you have multiple sondes attached, use the  
arrow key to select the correct one to calibrate.  
Depending upon the parameter you selected, a series of screens  
will be displayed to step you through the calibration process.  
• pH - You will be given the choice of three different pH  
solutions: 4.00, 7.00, and 10.00. After making your  
selection, rinse the probe and place in the pH buffer. If  
the reading is off by more than 0.5 pH units, you will  
asked to verify if the reading is correct.  
• DO - For dissolved oxygen, you can choose between two  
methods: DO Standard and Saturation. The saturation  
method requires a temperature reading between 0.0°  
and 47.0° C. You will also need to enter your altitude  
and barometric pressure.  
• ORP - You will asked to enter the value of your  
calibration standard.  
When calibration is complete, select “DONE” to proceed to the

Section 7 Remote Operation  
The 6712 controller can be operated remotely from external  
devices. External controlling devices may be a computer via  
RS-232 serial communications or a telephone via touch-tone com-  
mands. Remote telephone operation requires the  
factory-installed 2400 baud talking modem.  
7.1 Computer Operation  
The 6712 controller can be operated from a remote location using  
a computer. There are two different levels of computer control.  
One level—menu control—is used to start and stop the current  
sampler program (or programs if in Extended programming  
mode) and to access other menu commands. This level of remote  
operation relies on the sampler program for much of its capabil-  
ities.  
The second level—external program control—relies on external  
programmatic control to drive the operation of the sampler. The  
external controller can turn on the sampler, take a sample, and  
request sampler status data. When under external program  
control, the sampler controller program and current operation  
state are ignored. The pump, distributor, and serial data output  
simply respond to the external commands.  
Each level of operation is discussed in the following sections.  
However, before using either level of control you must first  
establish RS-232 serial communication between the computer  
and the 6712 controller. To do so:  
1. Connect your computer to the 6712 controller’s interroga-  
tor connector with a standard interrogator cable, P/N  
60-2544-044 (for 9-pin serial ports).  
2. Configure your communications software (HyperTerminal,  
for example) for:  
·
·
·
·
·
a baud rate no higher than 19,200  
no parity  
8 data bits  
1 stop bit  
VT100 terminal emulation.  
3. Using your communications software, connect to the sam-  
pler. Press “?” on the computer keyboard until the sampler  
returns its banner string. A “>” prompt will appear on the  
screen when it is ready to accept commands.

Section 7 Remote Operation  
7.1.1 Menu Control  
Menu commands can be entered from a remote location using a  
computer. The menu commands are listed in Table 7-1.  
To access the menu commands, type MENU at the “>” prompt  
and press ENTER. The screen will return a list of the available  
options. Note that the current state of the controller will  
determine the available menu options. Then, type the desired  
command(s), confirming with ENTER.  
Table 7-1 6712 Remote Menu Commands  
Menu Command Description  
0 or START  
This command will start immediately any program that has been run and is currently waiting to  
start.  
1 or RUN1  
This command will load Program 1 as the sampler’s current Extended program, reset partition if  
the storage interval has been changed, and run the program. RUN1 is valid when the sampler  
is in standby, or when it is waiting for a start command. RUN1 will also run the current program  
while in Standard programming.  
2 or RUN2  
3 or RUN3  
4 or RUN4  
These commands will load the selected program number as the sampler’s current Extended  
program, reset partition data if the storage interval has changed, and run the program. They are  
valid when the sampler is in standby, or when it is waiting for a start command. The commands  
are available for Extended programming only.  
5 or DISABLE  
This command is similar in functionality to a pin F low signal (a signal typically used to enable or  
disable the sampler from a flow meter). At run time, the sampler starts with the sampler in the  
enabled state. DISABLE is valid while a program is running. If successful, a display of REMOTE  
ENABLE IS FALSE will be returned.  
A Remote Disable is the highest priority disable. If the sample is disabled with this command,  
no condition other than menu command 6, ENABLE, will allow the program to become enabled  
again.  
6 or ENABLE  
This command is used to re-enable a disabled sampler. ENABLE is valid while a program is  
running. If successful, a display of REMOTE ENABLE IS TRUE will be returned.  
7 or TAKE_SAMPLE This command causes the sampler currently running a program to take a sample. The sample  
will count as one of the program’s samples and is placed in the current bottle (Part A’s current  
bottle when using two-part programming). TAKE_SAMPLE is valid while the program is run-  
ning, after the start time, but not while in the MANUAL PAUSE screens. If successful, a  
response similar to PUMPING XXML SAMPLE INTO BOTTLE ## will be returned. If not, a  
response similar to NO SAMPLE, PROGRAM WAITING START will be returned.  
ST or STATUS  
This command causes the sampler to return its status information and current parameter data.  
SD or  
SCREEN_DUMP  
This command causes the sampler to return the information currently displayed on the sam-  
pler’s screen. The remote screen follows the sampler’s display as the information is updated.  
This mode can be used to observe from a remote location while the sampler is programmed  
on-site.  
P or PAUSE  
This command causes a sampler currently running a program to enter the MANUAL PAUSE  
menu. While you are connected in this mode, the sampler keypad becomes disabled, and your  
computer’s keypad will be redirected to simulate the sampler keypad. The following keys will be  
activated:  
<Enter>, decimal point, and number keys.  
<Esc>, S, or s = STOP.  
<Backspace>, L or l, and U or u = Left/Up arrows.  
R or r, and D or d = Right/Down arrows.

Section 7 Remote Operation  
Note  
You can retrieve the sampling reports at any time using the  
same serial connection. Type “Q” to exit the menu. Then at the  
> prompt, type “REPORT” and press Enter. The sampler con-  
troller will send reports as configured.  
7.1.2 External Program  
Control  
Under external program control, the pump and distributor  
operate according to received commands. An external program  
can be as simple as manually-entered commands to collect a  
sample when needed, or as complex as a user-developed process  
control program that directs sample collection according a  
system’s needs.  
The 6712 controller will respond to four commands:  
Turn on the sampler – If the sampler is OFF, the sampler  
responds by placing itself in the ON state and returning a status  
string to report the new status. (See Send Status for a  
description of this string.)  
The command to turn the sampler ON is:  
STS,2  
Note that commands and responses are comma-separated pairs.  
The first set of alpha-characters are an identifier; the second set  
of numeric characters indicate the value. The 6712 controller will  
not receive and process the command unless it is followed by a  
carriage return.  
Checksum optional  
Optionally, commands to the sampler can be validated using a  
checksum. Checksum validation can avoid problems caused by  
faulty program control or communication lines. When using the  
checksum, add the CS identifier and a comma at the end of the  
command. and the checksum value of the string up to the last  
comma. For example, the command with checksum validation to  
turn the sampler on would appear as:  
STS,2,CS,582  
The numeric value of each character is its ASCII equivalent  
expressed in decimal format. The checksum of “582” was calcu-  
lated as shown below.

6712SR Refrigereated Sampler  
Section 7 Remote Operation  
Take a Sample – This directs the sampler to take a sample. The  
command specifies how much volume to take, and which bottle to  
place the sample in. The sampler responds by taking a sample  
and returning a status string that reports the new status. A  
command to take a sample would appear as:  
BTL,2,SVO,100,CS,1039  
This example instructs the sampler to place the distributor arm  
over bottle 2 (BTL,2) and take a 100 ml sample (SVO,100).  
While most settings of the sampler program (start times,  
enables, distribution schemes, etc.) are ignored when responding  
to external commands, the sampler does rely on two program set-  
tings that “configure” the sampler. These settings are:  
• Number of Bottles–is used to determine the distributor  
arm position and the acceptable range for the BTL  
values.  
• Suction Line Length–Used with liquid detection to  
deliver correct sample volumes according to the SVO  
value.  
Send Status – When receiving this command, the sampler  
returns a data string that identifies the controller and lists its  
current status.  
The status is received as pairs of comma-separated identifiers  
and values. A complete description of each pair is listed below.  
MO,6712, is the model number of the sampler.  
ID,2424741493, is the sampler’s unique ID number.  
TI,35523.50000, is the sampler’s current time.  
STS,1, is the sampler’s current status. The possible states  
are:  
1 = WAITING TO SAMPLE.  
4 = POWER FAILED (for short time after power is  
restored).  
5 = PUMP JAMMED (must be resolved before continu-  
ing).  
6 = DISTRIBUTOR JAMMED (must be resolved before  
continuing).  
9 = SAMPLER OFF.  
12 = SAMPLE IN PROGRESS.  
20 = INVALID COMMAND. Possible causes may be:  
· identifier code is not supported.  
· bottle requested is not in current configuration  
· sample volume requested is outside its range  
(10 - 9990 ml)  
· day (Set_Time) must be 5 digits and more  
recent than 1977  
21 = CHECKSUM MISMATCH.  
22 = INVALID BOTTLE. (bottle requested is not in the  
current configuration)

6712SR Refrigereated Sampler  
Section 7 Remote Operation  
23 = VOLUME OUT OF RANGE. (the sample volume  
requested is outside its range (10-9990 ml)  
STI,35523.41875, is the most recent sample time.  
BTL,2, is the bottle receiving the most recent sample.  
SVO,100, is the most recent sample’s volume.  
SOR,0, is the results of attempting the most recent sample.  
The possible results are:  
· 0 = SAMPLE OK.  
· 1 = NO LIQUID FOUND.  
· 2 = LIQUID LOST (not enough liquid to satisfy  
requirements.)  
· 3 = USER STOPPED (using the Stop Key).  
· 4 = POWER FAILED.  
· 5 = PUMP JAMMED.  
· 6 = DISTRIBUTOR JAMMED.  
· 8 = PUMP LATCH OPEN.  
· 9 = SAMPLER SHUT OFF (while sampling).  
· 11 = NO DISTRIBUTOR.  
· 12 = SAMPLE IN PROGRESS.  
CS,xxxx is the byte-by-byte sum of the entire string  
MO,...,CS,”  
Note  
For commands that are not understood (INVALID COMMAND  
or CHECKSUM MISMATCH) or when no samples have been  
taken, the most recent bottle information is left off the response  
string.  
Send Data – When receiving this command, the sampler  
returns the Send Status appended with data from any module,  
rain gauge, or SDI-12 device. Refer to Table 7-2 to interpret the  
returned string.

7.2 Telephone Commands 6712 controllers equipped with an internal voice modem can be  
operated using telephone commands. This factory-installed  
option includes a 12 ft (3.6 m) modem cable.  
After connecting to the sampler from a touch-tone telephone,  
command numbers may be entered from the telephone’s keypad,  
followed by the # (pound) button. The commands are listed in  
To use telephone commands:  
1. Dial the sampler’s telephone number. When the sampler  
connects, it answers with “Teledyne Isco Sampler Site  
[number].” If the sampler does not receive a touch-tone  
command in five seconds, it assumes that a computer  
modem has called and initiates the modem connect  
sequence. If this occurs you must hang up and try again.  
2. Enter the command. For example, to run program 1, press

3. If the command is valid for its current state of operation,  
the sampler responds with “[command number], please  
acknowledge.” If the command is not valid the sampler  
responds with the command number followed by three  
quick beeps. Enter a valid command.  
4. Acknowledge the valid command by pressing the number.  
For the example, press 1 .  
5. If the number is incorrect, the sampler responds with your  
entry followed by three quick beeps. You must re-enter the  
command (step 2).  
6. After the command is confirmed, the sampler replies with  
“[command number] acknowledge” and executes the com-  
mand.  
To enter additional commands, repeat steps two through five.  
The sampler will hang up after ten seconds of quiet time.

the current bottle (Part A’s current bottle when using two-part programming).  
TAKE_SAMPLE is valid while the program is running, after the start time, but  
not while in the MANUAL PAUSE screens. If successful, a response similar to  
PUMPING XXML SAMPLE INTO BOTTLE ## will be returned. If not, a  
response similar to NO SAMPLE, PROGRAM WAITING START will be  
returned.

8.1 Maintenance  
Checklist  
• Clean the condenser coil annually.  
• Clean the refrigerator’s air filter every 3 months.  
• Clean the refrigerator interior and exterior periodically.  
• Inspect the pump tube for wear. Replace it if necessary.  
• Clean the pump tubing housing.  
• Change the suction line if necessary.  
• Clean the bottles, suction line, strainer and pump tube.  
• Check the humidity indicator.  
• Check the controller’s internal battery status and  
replace the battery every five years.  
• If the keypad label has bubbles under it, the air inside  
the controller has expanded. To release this pressure,  
unscrew the flow meter cable or cap on the back of the  
controller. Push down on the label to force the air out,  
then re-tighten the cable connector or cap.  
8.2 Cleaning Guidelines  
8.2.1 Refrigerator  
To keep the refrigerator’s exterior and interior free from cor-  
rosive solutions, grease, oil, and other debris, clean it periodically  
with soapy water using a sponge or nonmetallic brush. Do not  
direct a hose spray toward the underside or into the front grille.  
Wipe the refrigerator dry after cleaning. Apply a coat of fiber-  
glass wax to the exterior surfaces to make them easier to clean  
and to protect them from damage.  
8.2.2 Controller  
When necessary, clean the controller with warm soapy water. To  
prevent moisture damage, always cap the connectors at the back  
of the controller tightly. Keep the controller power cable con-  
nected, or replace the protective cap (shipped with the sampler)  
over the power source connector.

6712SR Refrigerated Sampler  
Section 8 Maintenance  
Make sure the two pump drain holes (located on the bottom  
right-hand side of the pump, beneath the pump band) are open  
and free of debris or buildup.  
8.2.3 Sample Bottles  
The sample bottles have a wide mouth to facilitate cleaning.  
Wash them with a brush and soapy water, or use a dishwasher.  
You can autoclave the glass bottles.  
8.2.4 Suction Line, Pump  
Tube, and Discharge  
Tube  
Clean the suction line, pump tube, and discharge tube by placing  
the end of the suction line in a cleaning solution and pumping it  
through the delivery system. Rinse with clean water. If these  
items are severely contaminated, discard them. For critical sam-  
pling applications, refer to Section 8.3, Cleaning Protocols for  
Priority Pollutants.  
8.2.5 Strainer  
8.2.6 Air Filter  
Clean the strainer with a brush and soapy water.  
The air filter prevents dust, lint, and other debris from circu-  
lating around the cooling system. Clean the filter about every 3  
months; more frequently under severe operating conditions.  
To remove the filter:  
1. Disconnect power from the refrigerator.  
2. Remove the screws securing the refrigerator’s grille. (See  
Appendix D Replacement Parts.)  
3. Remove the grille and filter.  
4. Steam clean the filter or wash it in hot, soapy water. After  
washing, treat the filter with a standard filter coat.  
8.2.7 Condenser  
Clean the condenser and surrounding areas annually; more fre-  
quently under severe operating conditions.  
1. Disconnect power from the refrigerator.  
2. Remove refrigerator’s back panel. (See Appendix D,  
Replacement Parts).  
3. Vacuum the fan, compressor, and surrounding areas.  
4. Check the fan for freedom of movement. If the fan and fan  
motor do not rotate freely, replace the motor. (You cannot  
oil the sealed fan motor bearings.)  
5. Remove the front grille and filter. Vacuum the condenser  
coil and surrounding areas.  
6. Clean the filter before replacing it.  
7. Replace the back panel and front grille.  
8.3 Cleaning Protocols for Clean sampling equipment is essential for valid laboratory  
analysis. Teledyne Isco recommends that you develop cleaning  
Priority Pollutants  
protocols in consultation with a laboratory analyst when  
designing the monitoring program. For example, to clean sample  
bottles, suction line, and pump tubes, Lair (1974) suggests these  
protocols used by USEPA Region IV Surveillance and Analysis  
field personnel engaged in NPDES compliance monitoring. The

8.4.2 Pump Tube Alarm  
The sampler tracks the pump counts in both the forward and  
reverse cycles with a resettable counter. When the counter  
reaches the default count of 1,000,000 or the count you have  
entered, the sampler displays a message, “WARNING!  
REPLACE PUMP TUBE.” The message appears each time you  
turn the sampler on or run a program until you reset the counter.  
After replacing the pump tube (see page 8-8), reset the count to  
zero so the sampler can begin tallying the pump counts for the  
new tube. Replacing the pump tube does not reset the counter.  
Experience may suggest a significantly different pump tube life.  
You can change the alarm count to represent the pump tube life  
for your application. The example below shows how to set the  
alarm count and reset the pump counts.

8.4.4 Diagnostics  
The sampler has several self-diagnostic tests that check the  
memory (both the RAM and ROM), pump, and the distributor  
arm position. It also contains screens that let you reset the  
sampler’s program settings and memory to factory settings.  
You do not need to run the diagnostic tests on a routine basis.  
The diagnostic tests are a troubleshooting tool; Teledyne Isco’s  
Customer Service department staff may ask you to run these  
tests when they work with you in diagnosing problems with your  
sampler.  
Access the diagnostic screens by selecting Other Functions from  
the main menu, then Maintenance, and Diagnostics. The unit  
will automatically test the memory and display; you can choose  
whether it tests the pump and distributor, and whether it reini-  
tializes the unit to its original factory settings.

Section 8 Maintenance  
CAUTION  
Tests indicate that the pump produces sound levels in excess  
of 85db at one meter. Prolonged exposure to this sound level  
could result in hearing loss and requires the use of protective  
ear plugs.  
Distributor Test – The distributor test is provided for factory  
personnel to verify the distributor’s position as it rotates through  
the 24 positions. (screens 9 through 11). The distributor arm  
flexes slightly when it contacts the stop, and the sampler mea-  
sures this flexure. The sampler uses this measurement to  
position the arm accurately over each bottle.  
Reinitialize Controller – The sampler allows you to reset all  
the program settings to the settings shipped with the sampler  
(screen 12). Reinitializing also clears the memory that stores the  
sampler’s event log and module data. Use this option cau-  
tiously.  
8.5 Replacing the Pump  
Tube  
Replace the pump tube only with Teledyne Isco’s 6712 pump  
tubing. Other pump tubes will not work. The 6712 pump  
tubing is easily recognized by the blue alignment collars.  
Improper pump tubes include those made for Teledyne Isco’s  
other samplers (3700, GLS, etc.) and tubing from non-Teledyne  
Isco vendors. Also note that the discharge tube is not the same as  
the pump tube. You could experience several problems if you  
install the wrong pump tubing:  
• The sampler will not pump the liquid.  
• Pump jams  
• Inaccurate sample volumes  
• Faulty liquid detection  
Inspect the pump tube periodically. Replace the tube when it  
cracks or appears worn. Inspect the tube frequently when the  
sample liquid contains a high percentage of suspended or  
abrasive solids.  
Checklist For Replacing Pump Tube:  
1. Disconnect power from the sampler.  
2. Loosen the liquid detector’s cover by unscrewing the black  
knob on top of the detector. Unlatch the pump band. (The  
band is the rounded metal band that holds the tube in the  
pump.)  
3. Pull the tube away from the bulkhead fitting. Pull it from  
the pump and detector.  
4. Clean the pump rollers and the inside of the pump band.  
5. Thread the new tubing through the pump so that the tube  
follows its natural curve around the pump rollers. You may  
need to move the pump rollers to make the installation  
easier.

6712SR Refrigerated Sampler  
Section 8 Maintenance  
6. The blue collars on the tube help align the tube in the  
detector and pump. Align the tube by placing the collars in  
the grooves inside the liquid detector.  
7. Close the detector’s cover and tighten the black knob. Close  
the pump strap and latch it.  
8. Reset the pump-tube counter. (See example in table 8-2.)  
9. Take a “dry” grab sample to test the tube installation.  
WARNING  
The pump’s safety lock prevents the sampler from running  
the pump when the pump band is open. DO NOT tamper  
with the safety mechanism. The pump is extremely  
powerful. The pump rollers can injure you severely if the  
sampler activates the pump while you are working on it or  
inside it. Disconnect power from the sampler before  
replacing the pump tube.  
Note  
To extend the pump-tube life:  
• Always use Teledyne Isco pump tubes.  
• Install the tube properly, aligning the blue collars correctly in  
the liquid detector’s grooves.  
• Follow the natural curve of the tube when wrapping the tube  
around the pump rollers.  
• Minimize the line rinses and sampling retries in the sampling  
programs  
• Use the shortest possible suction line.  
Conditions that shorten tube life:  
• Improper installation.  
• Abrasive materials suspended in sample liquid.  
• Frequent line rinses.  
• Long purge cycles, such as those used with long suction  
lines.

8.6 Opening the  
Controller Case  
You will need to open the controller case to gain access to:  
• The desiccant bag that dries the controller’s interior  
• The battery that provides backup power to the controller  
CAUTION  
The circuit boards can be damaged from a discharge of static  
electricity. Always use an antistatic mat when opening the con-  
troller to protect the circuit boards.  
To open the case:  
1. Pull the discharge tube and pump tube away from the  
bulkhead fitting.  
2. Remove the distributor arm by unscrewing the nut that  
attaches the arm to the distributor shaft. DO NOT  
ROTATE THE DISTRIBUTOR ARM MANUALLY;  
THIS WILL SEVERELY DAMAGE THE DISTRIBU-  
TOR DRIVE GEARS.  
3. Remove the controller from the refrigerator.  
4. Open the case by removing the 11 screws that attach the  
case bottom to the case top.  
Note  
The case top and bottom fit together with a sealed  
tongue-and-groove joint. Any damage — nicks or cuts — to  
the tongue, groove, or sealing gasket prevent the case from  
sealing completely when you close it. Use extreme care when  
opening the case to avoid damaging the joining surfaces.  
Refer to Figure 8-3 for the location of the desiccant box. To gain  
access to the main circuit board and battery, remove the two dis-  
tributor connectors and the EMI shield.  
8.7 Replacing the  
Desiccant  
A humidity indicator, labeled “INTERNAL CASE HUMIDITY,” is  
located to the right of the keypad. It indicates the amount of  
moisture present inside the control box. The paper indicator is  
blue when the control box is dry.  
The control box is a completely sealed unit. You do not need to  
open the control box during normal operation. The 6712 Sam-  
plers use a desiccant bag inside the controller case to prevent  
moisture damage to its electronic components. Thus, the  
humidity indicator should remain blue under normal conditions.  
If moisture does accumulate, the numbered areas on the indi-  
cator will turn light pink or white, starting with the area num-  
bered “20.” This indicates that the relative humidity inside the  
8-11  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
6712SR Refrigerated Sampler  
Section 8 Maintenance  
control box exceeds 20%. As more moisture accumulates, the  
areas numbered “30” and “40” will turn light pink or white, indi-  
cating relative humidities of 30% and 40% respectively.  
If the 30% area of the humidity indicator turns light pink or  
white, open the control unit, inspect it for leaks, and replace the  
desiccant bag.  
CAUTION  
Do not attempt to reactivate the used desiccant. Reactivation  
may cause desiccant to leak out of the bag, causing mechani-  
cal damage inside the controller.  
Follow the instructions in Opening the Controller Case in Section  
8.6 to open the controller. Remove the bag from the cardboard  
box (part #69-9003-518) at the front of the case and replace it  
with a fresh bag of desiccant (part #099-0002-00).

8.8 Replacing the Internal  
Battery  
A lithium battery housed inside the controller maintains power  
to the sampler’s memory when the controller is disconnected  
from a power source. If it discharges completely, the sampler will  
lose all program settings and all data stored in memory when the  
external power source is disconnected. The battery requires  
replacement every five years. The sampler keeps track of the  
time that has passed since the battery was installed. To view this  
information, select INTERNAL BATTERY form the Maintenance  
screen (see example at left). After five seconds, the sampler asks  
if you have replaced the internal battery (see example at left).

it records each error and the time it occurred in the Sampling  
Results and Combined Results report. It alerts you to the  
recorded errors by displaying the message, “ERRORS HAVE  
OCCURRED DURING PROGRAM.”  
Error Messages  
ERRORS HAVE OCCURED  
DURING PROGRAM  
If the sampler detects a low battery condition, it stops the  
running program and displays the “LOW BATTERY” error  
message. A low battery condition exists when five consecutive  
sample events have resulted in a POWER FAILED error  
message.  
FATAL ERROR  
NO DISTRIBUTOR ARM  
Fatal Error – The Fatal Error message will only show up if you  
are using a multiple bottle configuration and the distributor  
system fails. Failing the test can indicate any of the following  
conditions:  
• The distributor arm is not attached to the sampler.  
• The distributor-arm stop inside the center section is  
missing or broken.  
• The distributor drive mechanism inside the controller is  
malfunctioning.  
8.10 Pump Tube Warning  
Occasionally, the sampler displays a warning message to alert  
you to a potential problem. The warning, REPLACE PUMP  
TUBE, reminds you to check the condition of the pump tube.  
Instructions regarding the pump tube can be found elsewhere in  
this section.  
WARNING: REPLACE  
PUMP TUBE

Section 8 Maintenance  
8.11 Servicing the  
Refrigerator  
Before servicing the refrigerator, disconnect it from power. This  
precaution will protect you from the possibility of electric shock  
when working with the refrigerator.  
WARNING  
Removing the front or back panel exposes electrical and  
mechanical hazards. Disconnect the power before  
performing any service activities. Troubleshooting and  
repair activities should be performed by a qualified  
refrigeration technician.  
CAUTION  
Always purge the system with nitrogen. NEVER USE AIR to  
purge the system.  
Always recover the refrigerant.  
When recharging, do not leave a line tap in the refrigeration  
system because of possible corrosion or leakage problems.  
Access the electrical and refrigeration components by removing  
the sixteen screws on the back of the refrigerator (See Appendix  
D, Replacement Parts).

6712SR Refrigerated Sampler  
Appendix C General Safety Procedures  
The safety of the personnel who use the 671SR is a critical con-  
sideration. The following procedures, applicable to working in  
and around manholes and sewers, are those used by Black &  
Veatch, a respected consulting firm, and are published here by  
their permission.  
Field personnel must keep safety uppermost in their minds at all  
times. When working above ground, rules of common sense and  
safety prevail. However, when entering manholes, strict safety  
procedures must be observed. Failure to do so could jeopardize  
not only your own life, but also the lives of other crew members.  
WARNING  
The 6712 samplers have not been approved for use in  
hazardous locations as defined by the National Electrical  
Code.  
CAUTION  
Before you install any sampler, you must take the proper  
safety precautions. The following discussion of safety proce-  
dures offers only general guidelines. Each situation in which  
you install a sampler varies. You must take into account the  
individual circumstances of each installation.  
Additional safety considerations, other than those discussed  
here, may be required. Check applicable guidelines, codes, and  
regulations of federal, state, city, and county agencies.  
C.1 Hazards  
There are many hazards connected with entering manholes.  
Some of the most common hazards are:  
C.1.1 Adverse Atmosphere  
The manhole may contain flammable or poisonous gases or the  
atmosphere may be deficient in oxygen. Forced ventilation may  
be necessary.  
C.1.2 Deteriorated Rungs  
C.1.3 Traffic  
Manhole steps may be corroded and not strong enough to support  
a man. It may be difficult to inspect the rungs because of poor  
lighting.  
Whenever manholes are located in the traveled way, barricades  
and warning devices are essential to direct traffic away from an  
open manhole.

6712SR Refrigerated Sampler  
Appendix C General Safety Procedures  
C.1.4 Falling Objects  
Items placed near the manhole opening may fall and injure a  
worker in the manhole. All loose items should be kept away from  
the manhole opening. This applies to hand tools as well as  
stones, gravel and other objects.  
C.1.5 Sharp Edges  
C.1.6 Lifting Injuries  
C.2 Planning  
Sharp edges of items in or near a manhole may cause cuts or  
bruises.  
Unless proper tools are used to remove manhole covers, back  
injuries or injuries to hands or feet may result.  
Advance planning should include arrangements for test  
equipment, tools, ventilating equipment, protective clothing,  
traffic warning devices, ladders, safety harness, and adequate  
number of personnel. Hasty actions may result in serious injuries.  
Time spent in the manhole should be kept to a minimum.  
C.3 Adverse Atmospheres  
[Refer to the table of Hazardous Gases at the end of this  
appendix.] Before workers enter a manhole, tests should be made  
for explosive atmosphere, presence of hydrogen sulfide, and  
oxygen deficiency. Combustible or toxic vapors may be heavier  
3
than air, so the tests on the atmosphere must be run at least /4 of  
the way down the manhole.  
Whenever adverse atmosphere is encountered, forced ventilation  
must be used to create safe conditions. After the ventilating  
equipment has been operated for a few minutes, the atmosphere  
in the manhole should be retested before anyone enters the  
manhole.  
When explosive conditions are encountered, the ventilating  
blower should be placed upwind to prevent igniting any gas that  
is emerging from the opening. When a gasoline engine blower is  
used, it must be located so that exhaust fumes cannot enter the  
manhole.  
If testing equipment is not available, the manhole should be  
assumed to contain an unsafe atmosphere and forced ventilation  
must be provided. It should never be assumed that a manhole is  
safe just because there is no odor or the manhole has been  
entered previously.  
C.4 Entering Manholes  
Since the top of the manhole is usually flush with the sur-  
rounding surface, there may not be anything for the person who  
is entering the manhole to grab on to steady himself. Persons  
who are entering manholes should not be permitted to carry any-  
thing in their hands as they enter the manhole, to ensure that  
their hands will be free to hold on or grab if they slip. A good  
method for entering a manhole is to sit on the surface facing the  
manhole steps or ladder, with the feet in the hole and the arms  
straddling the opening for support. As the body slides forward  
and downward, the feet can engage a rung, and the back can rest  
against the opposite side of the opening. If there is any doubt  
about the soundness of the manhole steps, a portable ladder  
should be used.

6712SR Refrigerated Sampler  
Appendix C General Safety Procedures  
A person should never enter a manhole unless he is wearing per-  
sonal safety equipment, including a safety harness and a hard  
hat. Two persons should be stationed at the surface continuously  
while anyone is working inside a manhole, to lift him out if he is  
overcome or injured. One man cannot lift an unconscious man  
out of a manhole.  
The persons stationed at the surface should also function as  
guards to keep people and vehicles away from the manhole  
opening. To avoid a serious injury, a person should not be lifted  
out of manhole by his arm unless it is a dire emergency.  
“When more than one person must enter a manhole, the first  
person should reach the bottom and step off the ladder before the  
next one starts down. When two men climb at the same time, the  
upper one can cause the lower one to fall by slipping or stepping  
on his fingers.  
C.4.1 Traffic Protection  
In addition to traffic cones, markers, warning signs, and barri-  
cades, a vehicle or a heavy piece of equipment should be placed  
between the working area and oncoming traffic. Flashing  
warning signals should be used to alert drivers and pedestrians.  
Orange safety vests should be worn by personnel stationed at the  
surface when the manhole is located in a vehicular traffic area.  
C.4.2 Removing the Covers  
Manhole covers should be removed with a properly designed  
hook. Use of a pick ax, screwdriver, or small pry bar may result  
in injury. A suitable tool can be made from 3/4-inch round or hex  
stock. Two inches of one end should be bent at a right angle and  
the other end should be formed into a D-handle wide enough to  
accommodate both hands. Even with this tool, care must be exer-  
cised to prevent the cover from being dropped on the toes. The  
2-inch projection should be inserted into one of the holes in the  
cover, the handle grasped with both hands, and the cover lifted  
by straightening the legs which have been slightly bent at the  
knees.  
C.4.3 Other Precautions  
Other precautions which should be taken when entering a  
manhole are:  
• Wear a hard hat.  
• Wear coveralls or removable outer garment that can be readily  
removed when the work is completed.  
• Wear boots or nonsparking safety shoes.  
• Wear rubberized or waterproof gloves.  
• Wear a safety harness with a stout rope attached.  
• Do not smoke.  
• Avoid touching yourself above the collar until you have  
cleaned your hands.  
C.4.4 Emergencies  
Every member of the crew should be instructed on procedures to  
be followed in cases of an emergency. It is the duty of each crew  
chief to have a list of emergency phone numbers, including the  
nearest hospital and ambulance service, police precinct, fire  
station, and rescue or general emergency number.

C.4.6 Lethal Atmospheres in  
Sewers  
The following is an article written by Dr. Richard D. Pomeroy,  
and published in the October 1980 issue of “Deeds & Data” of the  
WPCF. Dr. Pomeroy is particularly well known for his studies,  
over a period of nearly 50 years, in the field of the control of  
hydrogen sulfide and other odors in sewers and treatment plants.  
He has personally worked in a great many functioning sewers. In  
the earlier years he did so, he admits, with little knowledge of  
the grave hazards to which he exposed himself.  
“It is gratifying that the subject of hazards to people working in  
sewers is receiving much more attention than in past years, and  
good safety procedures are prescribed in various publications on  
this subject. It is essential that people know and use correct pro-  
cedures.  
“It is less important to know just what the hazardous compo-  
nents of sewer atmospheres are, as safety precautions should in  
general be broadly applicable, but there should be a reasonable  
understanding of this subject. It is disturbing to see statements  
in print that do not reflect true conditions.  
“One of the most common errors is the assumption that people  
have died from a lack of oxygen. The human body is able to  
function very well with substantially reduced oxygen concentra-  
tions. No one worries about going to Santa Fe, New Mexico, (elev.  
2,100 meters), where the partial pressure of oxygen is equal to  
16.2% (a normal atmosphere is about 21%) oxygen. “When first  
going there, a person may experience a little ‘shortness of breath’  
following exercise.  
“People in good health are not afraid to drive over the high  
passes in the Rocky Mountains. At Loveland Pass, oxygen  
pressure is 13.2% of a normal atmosphere. At the top of Mt.  
Whitney, oxygen is equal to 12.2%t. Many hikers go there, and to  
higher peaks as well. After adequate acclimation, they may climb  
to the top of Mt. Everest, where oxygen is equal to only 6.7%.  
“The lowest oxygen concentrations that I have observed in a  
sewer atmosphere was 13 percent. It was in a sealed chamber,  
near sea level, upstream from an inverted siphon on a metro-  
politan trunk. A man would be foolish to enter the chamber.  
Without ventilation, he might die, but not from lack of oxygen.  
“It seems unlikely that anyone has ever died in a sewer from suf-  
focation, that is, a lack of oxygen. Deaths have often been  
attributed to asphyxiation.’ This is a word which, according to  
the dictionary, is used to mean death from an atmosphere that

does not support life. The word has sometimes been misinter-  
preted as meaning suffocation, which is only one kind of asphyxi-  
ation.  
“In nearly all cases of death in sewers, the real killer is hydrogen  
sulfide. It is important that this fact be recognized. Many cities  
diligently test for explosive gases, which is very important, and  
they may measure the oxygen concentration which usually is  
unimportant, but they rarely measure H2S. Death has occurred  
where it is unlikely that there was any measurable reduction in  
the oxygen concentration. Waste water containing 2 mg per liter  
of dissolved sulfide, and at a pH of 7.0, can produce, in a chamber  
with high turbulence, a concentration of 300 PPM H2S, in the  
air. This is considered to be a lethal concentration. Many people  
have died from H2S, not only in sewers and industries, but also  
from swamps and from hot springs. In one resort area, at least  
five persons died from H2S poisoning before the people were  
ready to admit that H2S is not a therapeutic agent. Hardly a  
year passes in the US. without a sewer fatality from H2S as well  
as deaths elsewhere in the world.  
“The presence of H2S in a sewer atmosphere is easily deter-  
mined. A bellows-and-ampoule type of tester is very satisfactory  
for the purpose, even though it is only crudely quantitative.  
When using a tester of this type, do not bring the air to the  
ampoule by way of a tube, as this may change the H2S concen-  
tration. Hang the ampoule in the air to be tested, with a suction  
tube to the bulb or bellows.  
“Lead acetate paper is very useful as a qualitative indicator. It  
cannot be used to estimate the amount of sulfide, but it will  
quickly turn black in an atmosphere containing only a tenth of a  
lethal concentration.  
“Electrodes or other similar electrical indicating devices for H2S  
in air have been marketed. Some of them are known to be unre-  
liable, and we know of none that have proved dependable. Do not  
use one unless you check it at frequent intervals against air con-  
taining known H2S concentrations. A supposed safety device  
that is unreliable is worse than none at all.  
“Remember that the nose fails, too, when it comes to sensing  
dangerous concentrations of H S.

“Various other toxic gases have been mentioned in some publica-  
tions. It is unlikely that any person has been asphyxiated in a  
sewer by any of those other gases, except possibly chlorine. The  
vapor of gasoline and other hydrocarbons is sometimes present in  
amounts that could cause discomfort and illness, but under that  
condition, the explosion hazard would be far more serious. The  
explosimeter tests, as well as the sense of smell, would warn of  
the danger. Pipelines in chemical plants might contain any  
number of harmful vapors. They, too, are sensed by smell and  
explosimeter tests if they get into the public sewer. Such occur-  
rences are rare.  
“The attempt to instill a sense of urgency about real hazards is  
diluted if a man is told to give attention to a long list of things  
that in fact are irrelevant.

Appendix C General Safety Procedures  
“Be very careful to avoid high H2S concentrations, flammable  
atmospheres, and hazards of physical injuries. Remember that  
much H2S may be released by the stirring up of sludge in the  
bottom of a structure. Obey your senses in respect to irritating  
gases, such as chlorine (unconsciousness comes suddenly from  
breathing too much). Be cautious about strange odors. Do not  
determine percent oxygen in the air. There is a danger that the  
result will influence a man's thinking about the seriousness of  
the real hazards. Most important, use ample ventilation, and do  
not enter a potentially hazardous structure except in a good  
safety harness with two men at the top who can lift you out.”
