Safety Precautions  
Hazardous Locations  
The Sigma 900 MAX Refrigerated Sampler is not approved for use in  
hazardous locations as defined in the National Electrical Code.  
DANGER  
DANGER  
Although some Sigma products  
are designed and certified for  
installation in hazardous  
locations as defined by the  
National Electrical Code, many  
Sigma products are not suitable  
for use in hazardous locations. It  
is the responsibility of the  
individuals who are installing the  
products in hazardous locations  
to determine the acceptability of  
the product for the environment.  
Additionally, to ensure safety, the  
installation of instrumentation in  
hazardous locations must be per  
the manufacturer's control  
drawing specifications. Any  
modification to the  
Bien que certains produits Sigma soient conçus et certifiés pour être installés  
dans des endroits dangereux tels que définis par le National Electric Code, de  
nombreux produits Sigma ne conviennent pas pour de tels endroits. Il relève de  
la responsabilité des personnes qui placent les produits dans des endroits  
dangereux de déterminer s'ils sont adaptés à cet environnement. En outre, à des  
fins de sécurité, le placement de machines dans des endroits dangereux doit  
s'effectuer dans le respect des consignes des schémas de contrôle du fabricant.  
Toute modification apportée aux machines ou tout déplacement de celles-ci est  
déconseillé, car susceptible de provoquer des accidents matériels et/ou  
corporels.  
instrumentation or the  
installation is not recommended  
and may result in life threatening  
injury and/or damage to facilities.  
Confined Space Entry  
Important Note: The following  
information is provided to guide  
users of samplers on the dangers  
and risks associated with entry into  
confined spaces.  
On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required  
Confined Spaces, became law. This new standard directly affects more than  
250,000 industrial sites in the United States and was created to protect the  
health and safety of workers in confined spaces.  
Definition of Confined Space  
A Confined Space is any location or enclosure that presents or has the  
immediate potential to present one or more of the following conditions:  
•
•
•
An atmosphere with less than 19.5% or greater than 23.5% oxygen  
and/or more than 10 ppm Hydrogen Sulfide (H S)  
2
An atmosphere that may be flammable or explosive due to gases, vapors,  
mists, dusts, or fibers  
Toxic materials which upon contact or inhalation, could result in injury,  
impairment of health, or death  
Confined spaces are not designed for human occupancy. They have restricted  
entry and contain known or potential hazards. Examples of confined spaces  
include manholes, stacks, pipes, vats, switch vaults, and other similar  
locations.  
Standard safety procedures must always be followed prior to entry into  
confined spaces and/or locations where hazardous gases, vapors, mists,  
dusts, or fibers may be present. Before entering any confined space check  
with your employer for procedures related to confined space entry

Introduction  
1.1 Controller Cover  
The controller is mounted on top of a specially designed refrigerator. The  
sample line passes through the top of the refrigerator and into the refrigerated  
compartment where the sample containter(s) are located. The compartment  
is surrounded by rigid foam insulation and utilizes a 120 CFM condenser fan.  
An optional controller cover locks and protects the controller from damage  
and unauthorized users.  
Sample temperature is controlled by an adjustable air sensing thermostat  
maintaining samples at 4 °C (39 °F) in ambients up to 50 °C (120 °F). The unit  
has a magnetic door seal and does not require rear ventilation. The  
refrigerator interior is food grade plastic and the exterior is coated galvanized  
steel (304 stainless steel is optional). As a further barrier against corrosion,  
the refrigeration components and copper plumbing are treated with phenolic  
resin coating.  
1.2 Front Panel  
The front panel (Figure 1) of the sampler consists of the keypad, liquid crystal  
display, and the internal case humidity indicator.

Status Bar  
The Status Bar appears along the bottom edge of the display.  
The appearance of the status bar changes depending upon the  
function performed (Figure 1). The lower left corner of the Status Bar  
indicates whether a program is Complete, Running, Halted, or Ready To Start.  
If it is not needed during a programming step, it disappears.  
The lower right corner displays system alarm conditions, such as low memory  
battery, jammed distributor etc. For a list of possible alarms refer to  
section 6.4 on page 89. The status bar also lists the valid choices when  
entering certain programming information.  
1.2.3 Internal Humidity Indicator  
The round window of the internal case humidity indicator (Cat. No. 2660)  
turns pink when the internal case humidity exceeds 60 percent.  
The sampler is equipped with an internal desiccant module (Cat. No. 8849) to  
absorb any humidity that may have been trapped in the case during final  
assembly. Under normal operating conditions, this desiccant provides long-  
term protection against condensed moisture inside the case.  
Replacement of the internal desiccant module is only necessary if the  
indicator turns pink. (Refer to section 7.10 on page 103 for details on  
replacing the internal desiccant.)

1.4 Principle of Operation  
1.4.1 Liquid Sensing  
The sampler is designed for indoor, permanent installation. All controls are  
located on the front panel. Capped, watertight connectors for interfacing to  
external devices are located along the left side of the controller.  
The sampler uses a liquid sensing system to detect the absence or presence  
of liquid at the peristaltic pump intake. The liquid sensor (Figure 3) is located  
on the front of the control housing.  
The liquid sensing system provides three primary benefits:  
•
•
•
Accurate, repeatable sample volumes  
Intake tube prerinse  
Sample retry  
Figure 3

1. Sensor Body  
2. Sensor Cover  
3. Knobs (turn to remove)  
Accurate, Repeatable Sample Volumes  
The liquid sensor detects the presence and velocity of the incoming sample.  
This information allows the sampler to automatically dispense the correct  
amount of liquid into the sample bottle.  
The liquid sensing system allows the sampler to deliver repeatable sample  
volumes even with changing suction lifts. Each time the peristaltic pump pulls  
a sample, the microprocessor determines the time required for liquid to travel  
to the liquid sensor. If the suction lift increases due to a drop in level at the  
sample source, the time required for liquid to reach the sensor will increase.  
The microprocessor automatically compensates for this change by allowing  
the peristaltic pump to deliver sample liquid for a corresponding longer period  
of time. Conversely, if suction lift decreases due to an increase in level at the  
sample source, the time required for liquid to the sensor will decrease. Again,  
the microprocessor automatically compensates for this change by decreasing  
the sample delivery time.

Section 1  
Intake Tube Pre-Rinse  
The liquid sensor also rinses the intake tubing with the liquid from the sample  
source before taking each sample.  
Upon sample initiation, the pump purges the intake line. The pump then  
reverses, pulling liquid through the tubing, until it reaches the liquid sensor.  
When the sensor detects liquid, the pump purges back to the source, and  
then draws a sample. After the desired sample is collected, the pump purges  
the intake line and awaits the next sample cycle. The sampler can be  
programmed for up to 3 rinses before each sample.  
Sample Retry  
The liquid sensing system permits the sampler to repeat a collection cycle if a  
sample is not obtained during the regular cycle.  
The intake line length is user-programmed into the sampler memory. For a  
line length of 3 to 99 feet, the sampler has a built-in “look up” table that  
detects the maximum time required for liquid to reach the sensor. If liquid  
does not reach the sensor within the defined time period, the pump will  
automatically purge the intake line and initiate another sample cycle. The  
sampler may be programmed for up to three repeated attempts. If a sample is  
not obtained, the sampler retains in memory the time, date and reason for the  
missed sample.

2.3.2 Setting Up the Intake Line and Strainer  
Note: If site conditions do not permit  
the intake to slope downward from  
the sampler to the sample source,  
disable the liquid sensors by  
For each sampling location, the intake line should be as short as practical,  
and be free of any sharp bends, coils, or loops. Install the intake line with a  
downward slope from the sampler to the sample source because:  
calibrating the sample volume using  
the Timed Calibrate method when  
programming the sampler.  
•
This will ensure the complete drainage of the intake line when it is  
air-purged before and after each sample, and will help to prevent  
cross-contamination of the individual samples.  
•
Complete drainage is important in freezing conditions, as any liquid slugs  
that remain could freeze and plug the line and possibly damage the  
sampler.  
Note: Vertical lift should not exceed  
27 ft. If the site requires more lift,  
you may purchase the Remote  
Pump Option. The remote pump  
option is factory installed. Any  
remote pump installed outside the  
factory will void the warranty.  
Place the sample intake and strainer in the mainstream of the sampling  
source, in an area of turbulent and well mixed flow.  
Also, you must account for the vertical location of the intake. A position too  
near the surface may yield excess lighter materials, while a position too near  
the bottom may yield excess heavy materials. The constituents of interest  
must be considered when positioning the intake strainer.

2.6 Installing the Distributor (Multiple Bottle Operation)  
Note: Make sure the sampler is  
powered off before removing or  
installing the distributor.  
For multiple bottle sampling, a motorized arm (Distributor) is provided to  
automatically position the sample tube over the proper bottle. The  
microprocessor-controlled distributor arm can automatically locate two, four,  
eight, 12, or 24 discrete bottles.  
To install the distributor:  
1. Locate the two slots along one edge of the distributor assembly base  
plate (Figure 14). Slide the distributor assembly, slots first, under the  
shoulder screws located on the top inside surface of the controller  
section.  
2. When fully seated, hand tighten the knurled thumbscrew to hold the  
distributor in place.  
3. To ensure the arm has sufficient freedom of movement, hand-rotate the  
arm to the opposite end of the Arm Stop.  
4. Install the silicone distributor tubing to the sample fitting on the top  
underside surface of the controller housing.  
Note: Use care not to force the arm past the Arm Stop clip. The Arm Stop keeps the  
arm from being rotated more than 360 degrees and keeps the distributor tubing  
from kinking.  
The distributor tubing should be installed so that the end of the tubing extends  
out of the nozzle end of the distributor arm no more than 1/8 in. (Figure 13). Do  
not let the tubing extend more than 1/8 in. past the nozzle end of the arm.

2.8 Power Connections  
Note: Install the sampler on its own  
circuit to ensure a continuous,  
stable source of power.  
Use the ac power cords to apply ac power to the controller and  
the refrigerator.  
The sampler controller operates on a 12 V dc which is supplied by a built-in  
ac/dc power converter. The power supply is permanently sealed in the  
compartment located behind the transition plate. An ac line fuse is located on  
the left side of the controller.  
An optional power backup assembly is located on top of the ac power supply.  
The ac power backup is designed to power the pump and controller only. Pull  
the rubber hold-downs up and over the clips at each end of the ac Power  
Backup to hold it in place.  
The short, 2-pin cable on the power supply (or battery) connects to the  
controller receptacle labeled 12 V dc.

Section 2  
Important: Whenever electricity is present, there is a possibility of electrical  
shock. Before connecting the sampler to an ac power source, the following  
safety precautions should be taken:  
•
•
•
•
Check the power source to make sure that it satisfies the ac power  
requirements of the sampler.  
Make sure that all electrical installations and connections are in  
accordance with national and local electrical codes.  
Before performing any maintenance, disconnect the sampler from the  
power source.  
Do not attempt to make any connection or otherwise handle the electrical  
components of the sampler when connected to ac line power if the  
immediate area is wet, or if hands or clothing are wet.  
•
•
If the circuit breaker or fuse in the ac power source is tripped, determine  
the cause before restoring power to the sampler.  
Make sure the power circuit is grounded and protected with a Ground  
Fault Interrupter (GFI).  
2.9 Auxiliary Receptacle Pin Identification  
Pin A/White (12 V dc)  
Pin B/Blue (Ground)  
Powers an external device or flow meter. Must be used in conjunction with Pin B (ground).  
Connected to dc ground and is isolated from the earth ground found in the ac power line.  
With the sampler in Flow Proportional mode and connected to an external flow meter, a 5 to  
12 V dc input pulse lasting at least 25 milliseconds will cause the sampler to decrement one  
count. The 12 V dc line found on Pin A can be used directly with a simple contact closure to  
Pin C or an external 5 to 12 V dc pulse may be applied providing the ground side of the  
external signal is connected to the sampler ground at Pin B. This count is actuated at the  
beginning of the input signal (the leading edge of the pulse).  
Pin C/Yellow (Pulse Input)  
This line is held at 5 V dc inside the sampler. When shorted to ground (Pin B), a signal is sent  
to the microprocessor inside the sampler causing it to “wake up” and begin or resume its  
sampling program. It can be used in conjunction with a simple level float to actuate the  
sampler when liquid is present or to take over after a second sampler has finished its  
program. It may also be used with any device (such as a pH meter) that produces a dry  
contact output to control the sampler in response to some user-defined condition (i.e. high or  
low pH); must be used in conjunction with Pin B.  
Pin D/Black  
(Liquid Level Actuator/  
Auxiliary Control Input)  
Pin E/Red (Special Output) Normally at 0 V dc, this line goes to 12 V dc upon any of the selected events described in.  
Normally an open circuit, this line switches to ground for 90 seconds at the conclusion of the  
sampling program. Used to “wake up” another sampler to take over sampling or to signal an  
Pin F/Green  
operator or data logger upon the completion of the sampling program. This pin is also used to  
(Program Complete Output)  
signal the bottle full condition in a single bottle/continuous mode, and will transmit the bottle #  
to an 950 Flow Meter if the program complete signal is disabled.

2.9.1 Splitter Interface  
Use the Splitter Interface (Cat. No. 939) when more than one signal is needed  
simultaneously. Connecting the interface to the 6-pin connector on the  
sampler provides three additional connectors. Two or more interfaces may be  
connected in series to allow for additional connections.

Flow Proportional Constant Volume, Variable Time (CVVT)  
CVVT sampling is a flow-proportional method of sampling. CVVT samples are  
taken when a user-defined flow volume occurs in the flow stream. This occurs  
when the sampler is programmed to take a sample every time a specified  
volume of flow occurs in the flow stream. Specified flow volume intervals can  
vary with the flow rate of the stream, therefore varied time intervals can occur  
when constant (fixed) volume occurs.  
Flow volume is determined internally, by the optional integral flow meter or by  
an external flow meter.

Section 3  
Flow Proportional Constant Time, Variable Volume Sampling (CTVV)  
A Level-Velocity Sensor Input must be logged and electrically connected for  
the CTVV feature to work correctly.  
CTVV samples are taken at user-specified constant (fixed) intervals. However  
the actual volume of each sampling is based on the known average flow rate  
of the site, the actual metered flow rate for each specific interval, the total  
sample volume desired, the user-specified collection period, and the specified  
Sampling Interval. Depending on the flow volumes of a stream and various  
intervals within the Collection Period, the volume of individual sampling can  
vary. Also, the total sample collected during the entire period can carry slightly  
above or below the Total Volume Desired. For these reasons, the  
manufacturer advises to use a sampling container that has a larger volume  
than the Total Volume Desired value.  
•
•
Sample Distribution menus are not available when CTVV is selected.  
A level-velocity sensor input must be logged and electrically connected for  
the CTVV feature to correctly work.

Sampling will continue every 30 minutes until 25 samples are deposited.  
Once all samples are deposited the program will terminate. If Run  
Continuously is selected the sampling will restart automatically.  
Step 7 - Liquid Sensor  
The liquid sensor contains a pair of ultrasonic transducers which sense the  
presence of liquid inside silicone tubing.  
7-A. Enable or Disable Liquid Sensor using the CHANGE CHOICE key.  
Note: Sample retries cannot be  
enabled when the liquid sensor  
is disabled.  
Enabling the Liquid Sensor  
When the liquid sensor is enabled, the sampler will perform two duties:  
•
•
It senses when liquid reaches the pump during an intake cycle. The pump  
then reverses to rinse the line, up to three times.  
It senses the absence of liquid during a sample intake cycle if the intake  
tubing is plugged or if the water level has dropped below the level of the  
intake tube strainer. This initiates a Sample Retry if programmed  
Disabling the Liquid Sensor/Timed Calibration  
Disabling the liquid sensor turns the liquid sensor off. The sample volume is  
then metered using a timed method (Timed Calibration), instead of a  
sensed method.

Up to three intake rinses are enabled per sample cycle. After the sample  
cycle’s initial purge has been completed, the sample liquid is drawn in until it  
reaches the liquid sensor. The pump stops and purges the line before any  
liquid enters the bottle. This is repeated up to three times before the actual  
sample is taken and the line purged for the final time during that cycle.  
Intake rinse can prevent cross contamination of samples. When the line is  
purged at the end of each sample cycle, a few droplets of sample liquid may  
cling to the inside walls of the tubing and the droplets are drawn in with the  
following sample. Intake rinses will condition the intake line with a source  
liquid that minimizes contamination from the previous sample.  
Step 10 - Sample Retries  
Note: Excessive intake tube line  
lengths combined with multiple  
Intake Rinses and Sample Retries  
can increase the pump tube and  
drive train wear. Locate the sampler  
as close to the sample liquid source  
as possible to minimize wear and  
maintenance requirements.  
10-A. Enter the number of Sample Retries using the numeric keypad. Press  
ACCEPT to continue to Site ID.  
Up to three sample retries are enabled per sample cycle. After the initial purge  
is completed, the sample liquid is drawn until it reaches the liquid sensor. If  
the sample liquid does not reach the sensor within a reasonable time  
(determined using the tubing length), the sample attempt is aborted, a purge  
is initiated and the first of up to three sample retries is attempted.  
After three attempts and no sample liquid has been collected, the cycle is  
aborted, a Missed Sample is reported to the Sample History Log, and the  
sampler begins a new sample interval.

Step 12 - Program Complete Output  
Program Complete Output sends a +12 V dc signal out Pin F of the Auxiliary  
Receptacle at the completion of the sampling program. This signal is also sent  
when a Full Bottle condition causes the program to complete. The Program  
Complete signal remains on (+12 V dc) for 61 seconds and then turns  
back off (0 V dc).  
Program Complete Output is used for the following purposes:  
•
Multiple Sampler Operation. Samplers are arranged in a “Cascade”  
control where the first sampler signals a second sampler to start its  
program when the first sampler’s program is complete. This feature  
requires the second sampler to be programmed for external  
start operation.  
•

Step 16 - Storm Water  
EPA regulations for storm water discharges require monitoring of  
precipitation, flow, and water samples in order to assess the impact of storm  
or snow melt runoff on receiving waters. The manufacturer can help you  
create a storm water monitoring system that consists of a multiple bottle  
sampler, an external flow meter, and a tipping bucket rain gauge.  
In addition to performing basic sampling routines, 900 MAX Series Samplers  
that are equipped with the storm water monitoring program have the following  
additional capabilities:  
•
The storm water sampling routine allows collection of automatic grab  
sample(s) at user-selectable timed intervals (up to 24 different intervals  
may be selected) during the storm's early stage or “first flush.” First flush  
grab and main program flow weighted composite samples are  
automatically segregated. The first flush sample volume may be set  
independently of the sample volume for the flow weighted composite.  
•
•
The special storm water program allows an external device to initiate the  
start of the sampling program. A dry contact closure across Pins B and D  
on the Auxiliary receptacle, held closed for at least 61 seconds, is  
required.  
When sampling with multiple bottles, the sampler can be programmed to  
collect one large “first flush” sample (or small multiple samples) at timed  
interval(s). The number of bottles segregated for the first flush sample is  
selectable. Concurrently, flow weighted samples are collected from the  
beginning of the storm until all remaining bottle(s) are filled, or after a user  
selected time has elapsed.

•
Storm water samplers are equipped with a special prerinse that occurs  
only with the first sample collection. This “one time only” rinse ensures a  
clean intake for installations that may remain dormant for extended  
periods, and extends battery life by eliminating the prerinse for  
subsequent samples.

17-E. Press ACCEPT to continue to Upset Sample.  
Step 18 - Upset Sample  
Upset Sampling analyzes the collected samples to determine when samples  
meet or exceed specified upset limits. The sampler will swing the distributor  
arm around to a sequestered set of bottles and grab an upset bottle.  
The upset sample bottles are always the last bottles in the tray. For example, if  
there are 24 bottles in the tray, 4 first flush bottles and 4 upset bottles, then the  
bottles assignment is 1–4 first flush, 5–20 main program, and 21–24  
upset samples.  
Note: Unlike Setpoint Sampling,  
Upset Sampling can be enabled  
while the sampler is performing its  
regular sampling program. There  
must be more than one bottle in the  
sampler to perform Upset Sampling.  
Upset Samples are collected even when there are no more regular samples to  
be taken; when the status screen says Program Complete, but the bottom line  
of the display says Program Running.

Sensor Setup  
4.1 Downlook Ultrasonic Sensor  
4.1.1 Downlook Ultrasonic Sensor Connection  
The downlook ultrasonic sensor connection is located on the back side of the  
refrigerated cabinet. The gray rectangular box houses the ultrasonic module  
and the transducer connector labeled ULTRASONIC. The connector is keyed  
and can only be inserted in the proper orientation (key up).  
4.1.2 Downlook Ultrasonic Sensor Programming  
The downlook ultrasonic sensor does not require specific programming,  
unless more than one sensor option is connected to the sampler. When more  
than one sensor option is connected to the sampler:  
1. From the Main Menu, select OPTIONS>LEVEL SENSOR.  
2. Select Ultra-Sonic using the CHANGE CHOICE key. Press ACCEPT.  
4.1.3 Downlook Ultrasonic Sensor Calibration  
Calibrate the current water level via one of two methods; Liquid Depth or  
Sensor Height. An Invisible Range can also be set which allows the  
transducer to ignore reflections from obstructions between the sensor and the  
water surface, such as ladder rungs, channel side walls, etc. Each method  
has its own advantages and disadvantages; selecting the proper method will  
depend upon the site conditions. Calibrate the ultrasonic sensor each time the  
sensor is installed at a new site.  
4.1.3.1 Liquid Depth  
This method requires the level or depth of liquid in the channel that is  
contributing to flow. In a round pipe, the entire depth typically contributes to  
flow. In a weir, only the depth that is flow over the weir plate contributes to  
flow. Level Depth calibration is primarily used when:  
•
Access is available to the primary device for a physical measurement of  
the liquid depth, and  
•
When water is flowing during installation (channel is not dry).  
Note: Always re-check the  
Level Adjust when re-installing the  
flow meter.  
1. From the Main Menu, select OPTIONS>ADVANCED  
OPTIONS>CALIBRATION>ULTRASONIC SENSOR.  
2. Select Calibrate U-Sonic using the UP and DOWN keys. Press SELECT.  
3. Select Standard as the type of Ultrasonic Transducer using the CHANGE  
CHOICE key. Press ACCEPT to continue.  
Temperature Time Constant  
The speed of sound in air varies with the temperature of the air. The ultrasonic  
sensor is equipped with temperature compensation to help eliminate the  
effect of temperature variation under normal site conditions. The transducer  
must be equal to the ambient air temperature at the site prior to calibration for  
optimum results. The manufacturer recommends that sensors be shielded  
from direct sunlight for this reason.

Section 4  
4. Enter the ambient air temperature at the transducer location. For optimum  
results, allow enough time (100 minutes) to ensure that the sensor is at  
equilibrium with the surrounding ambient temperature. Press ACCEPT.  
5. Select the Liquid Depth method and enter the new level.  
6. Take a physical measurement of the liquid depth (level) and enter  
the value. Press ACCEPT when finished.  
4.1.3.2 Sensor Height  
This method requires entering the distance between the face of the ultrasonic  
sensor and the zero flow point in the primary device. The zero flow point in a  
primary device is the level at which flow ceases. In a round pipe the zero flow  
point would typically be the invert or bottom of the pipe. In a V-notch weir the  
zero flow point occurs when the liquid behind the weir is level with the bottom  
of the ‘V’. (There would still be liquid behind the weir plate but it would not be  
contributing to flow). Sensor Height calibration is generally used when:  
•
•
Access to the primary device is difficult (such as confined space entry in a  
manhole) or  
There is no liquid flowing during installation of the flow meter  
1. From the Main Menu, select OPTIONS>ADVANCED  
OPTIONS>CALIBRATION>ULTRASONIC SENSOR.  
2. Select Calibrate U-Sonic using the UP and DOWN keys. Press SELECT.

Recommended Routing of Submerged Area/Velocity Cable  
Proper routing of the cable serves two functions:  
•
•
Keeps the in-line desiccant assembly inside the cover and out of the way  
when installing and removing the sampler from tight manholes.  
Keeps the desiccant out of direct contact with the elements. Also, keeps  
water from dripping directly onto the desiccant assembly.  
To secure the submerged area velocity cable, route the cable around the  
battery and clip it under the battery hold downs.

4.2.3 Submerged Area/Velocity Submerged Area/Velocity Sensor Calibration  
This calibration requires a graduated cylinder or bucket with at least  
16 cm (6 in.) of water and a ruler. Calibrating the Submerged Area/Velocity  
Sensor characterizes the sampler electronics to the unique characteristics of  
each individual sensor. In addition, the calibration compensates for any  
sensor drift that may occur over time (6 months or greater) as the materials in  
the sensor age.  
The Submerged Area/Velocity Sensor is a pressure transducer that contains a  
stainless steel diaphragm. As the water pressure increases, (with increasing  
level in the flow stream) the diaphragm is deflected, or pushed, against a solid  
state device called a strain gauge. The strain gauge converts the pressure  
against the diaphragm to a voltage. As the level in the flow stream increases,  
so does the voltage coming from the Submerged Area/Velocity Sensor. The  
voltage is read by the microprocessor in the sampler at regular intervals and  
converted to a number that represents the level in the flow stream.  
The manufacturer recommends calibrating the submerged area/velocity  
sensor when:  
•
•
•
The sensor is first used.  
Installing a new or different sensor on a flow meter or input receptacle.  
The difference between the level reading of the flow meter and the  
independent verification (measurement with a dipstick or ruler)  
is increasing.  
Note: The data is constant if the difference between the level reading of the flow meter  
and the independent verification is constant; recalibration is not required.  
Note: Errors can occur with the flow meter level reading and the independent  
verification. Errors are caused by variation in site conditions and measurement  
abilities. These errors may cause slight changes in the difference, therefore, not  
indicating a true change in the difference.  
1. From the Main Menu, select OPTIONS > ADVANCED OPTIONS >  
CALIBRATION > SUBMERGED PROBE.  
2. Place the sensor flat on a table top or floor with the sensor (the plate with  
holes) facing down onto the surface (Figure 17). Press any key to  
continue.

Section 4  
3. Place the sensor face up in the bucket or liquid. Tap lightly to remove air  
bubbles. If these bubbles are not removed you can receive false readings  
from the sensor during calibration (Figure 17).  
Note: Always check the Level  
Adjust when reinstalling the sampler  
following a calibration. (See Keypad  
Description on page 16.)  
4. Place the sensor face down under at least 16 cm (6 in.) of water and wait  
20 seconds. Make sure the water surface is calm and the sensor is stable.  
5. Press any key to continue.  
6. Measure the depth from the bottom of the bucket to the surface of the  
water and enter the value using the numeric keypad (Figure 17).  
7. Press ACCEPT.  
Figure 17

4.3 Submerged Pressure Sensor  
The submerged pressure sensor is a pressure transducer that contains a  
titanium diaphragm. As the water pressure increases, (with increasing level in  
the flow stream) the diaphragm is deflected, or pushed, against a solid state  
device called a strain gauge. The strain gauge converts the pressure against  
the diaphragm to a voltage. As the level in the flow stream increases, the  
voltage coming from the submerged pressure sensor increases. The voltage  
is read by the microprocessor in the Sampler at a regular interval and  
converted to a number which represents the level in the flow stream. The level  
reading can then be converted by the meter to a flow rate based on the  
mathematical formula for the selected primary device.  
4.3.1 Submerged Pressure Sensor Connection  
The submerged pressure sensor connection is located on the left side of the

5.1 Rain Gauge  
An external “tipping bucket” rain gauge (Cat. No. 2149) can be connected to  
the Rain Gauge connector of the sampler (Figure 21). The rain gauge  
provides a dry contact closure to the sampler.  
As rainfall collects in the 20 cm (8 in.) diameter funnel, it is directed into one  
side of a “tipping bucket” assembly. As each bucket fills, it causes the bucket  
assembly to tip and empty out into the bottom of the rain gauge. Each tip of  
the bucket causes a single contact closure to the rain gauge and sends a  
short 12 V dc pulse into pin C of the Rain Gauge connector. Each pulse (tip)  
represents 0.025 cm (0.01 in.) of rain.

Store the probe in a pH 4.0 buffer (Cat. No. 2104) for both overnight and long  
term storage. Never store a probe in distilled or deionized water because this  
will deplete the probe filling solution.  
5.2.1 pH Probe Connection  
This connector is for installing the pH or ORP pre-amp interface junction box  
or a stand-alone temperature sensor. The pH probe is attached to a terminal  
strip in the junction box. The stand-alone temperature probe plugs directly into

Since the pH reading needs to compensate for temperature variation, a  
temperature sensor is built into every pH electrode. The pH probe consists of  
five wires, three for the pH probe and two for the temperature sensor.  
Stray electrical currents are sometimes found in wastewater stream. These  
stray electrical currents can affect the pH readings. In the case of stray  
electrical currents, a grounded pH probe is required. See Figure 22.

5.4.4 Dissolved Oxygen Probe Calibration  
The Dissolved Oxygen Probe is shipped without an electrolyte or membrane  
installed. Install these items before initial use.  
1. Connect a suitable power supply to the sampler, and power up the unit by  
pressing the ON button.  
2. From the Main Menu, select OPTIONS > ADVANCED OPTIONS >  
CALIBRATION > DO.  
3. Enter the ambient air temperature (the current reading is displayed for  
reference) using the numeric keypad.  
4. Enter the elevation above sea level for the specific location.  
5. Enter the membrane thickness. The operation of the sampler will be  
affected by membrane thickness for the oxygen sensor.  
Note: The membrane of a charged  
sensor must be kept moist. If the  
membrane is allowed to dry  
completely, the electrolyte film  
between the membrane and the  
platinum will evaporate,  
destabilizing the sensor. If the  
sensor will be out of water for more  
than 30 minutes, put a small amount  
of water in the silicon soaking cap,  
and install it over the protective  
guard. Lift the edge of the cap to  
break the seal as it is being  
For general purpose applications, the 1-Mil membrane is standard. This  
membrane allows measurements in the 0 to 20 ppm range of dissolved  
oxygen and provides the best response time and durability.  
The 2-Mil membrane can be used to measure up to 40 ppm dissolved oxygen.  
Its increased thickness slows the response time of the sensor, but this  
membrane has increased resistance to cuts and tears. For this reason, it is  
recommended for use in wastewater aeration basins where solids in the water  
are in rapid motion.  
6. Enter the chlorinity (salinity) of the flow stream (typical wastewater is zero,

removed. This will prevent a vacuum  
from forming inside the soaking cap  
while it is being removed which can  
result in the membrane becoming  
stretched.  
7. Place the D.O. probe in open air and press any key. The sampler will wait  
for the reading to stabilize before storing the calibration value. The screen  
will automatically return to the calibration menu.

5.5.4 Conductivity Probe Calibration  
1. From the Main Menu, select OPTIONS > ADVANCED OPTIONS >  
CALIBRATION > CONDUCTIVITY.  
2. Clean and dry the probe.  
3. Place the sensor and thermometer in the calibration solution  
(Cat. No. 3230). The temperature sensor is located in the middle of the  
sensor body allowing the probe to be completely submerged in  
the solution.  
4. Allow the sensor to stabilize in the solution about 10 minutes to ensure  
that the probe and the solution are the same temperature.  
5. Enter the temperature correction factor or enter zero for no correction  
factor.  
Note: The temperature correction factor is used to compensate for the effects of  
temperature on the conductivity readings at the point of installation. The  
conductivity of a solution is temperature sensitive. Therefore the actual  
conductivity of the solution will change with the temperature. Each site may have a  
different correction factor depending on the major constituent of the flow stream.  
This is not used for calibration and has no effect on the calibration of the sensor.  
Below are some examples of compensation factors of various liquids.

0.96%/°C 5% Sulfuric Acid  
1.88%/°C Dilute Ammonia  
1.91%/°C ‘Typical’ Wastewater

2.12%/°C Salt (Sodium Chloride)  
2.84%/°C 98% Sulfuric Acid  
4.55%/°C Ultra-pure Water  
6. With the sensor still in the calibration solution, press any key. Wait for the  
sensor to stabilize. Calculate the actual conductivity of the calibration  
solution. If using the KCl solution provided by the manufacturer, make  
your selection from the Table 12 on page 78. If using a solution other than  
1.0 mS @ 25 °C KCl available from manufacturer, calculate the  
conductivity of the solution using temperature correction factors. See the  
following example.  
Example: The KCl calibration solution is 1.0 mS at 25°C. If the actual  
temperature of the KCl at the time of calibration is 18.4 °C, then the solution  
has a conductivity value of 0.870 mS.  
a. Find the difference between the labeled temperature and the actual  
temperature of the calibration solution at the time of calibration.  
25 °C – 18.4 °C = 6.6 °C  
b. Multiply the difference (6.6) by the correction factor per °C (1.97% or  
0.0197).  
6.6 °C x 0.0197/°C = 0.13002

c. If the calibration temperature is lower than the labeled value, then  
subtract that value from the standard (1.0 mS) to get the actual value  
to be used for calibration.  
1.0 mS - (correction factor) 0.13002 = 0.86998 mS  
d. If the calibration temperature is higher than the labeled value, then  
add that value to the standard (1.0 mS) to get the actual value to be  
used for calibration.  
7. Using the value that was calculated in step 6, enter the conductivity of the  
solution then press ACCEPT to complete the calibration.  
Calibrating the Conductivity Temperature  
Note: Conductivity temperature  
calibration is only necessary when  
logging temperature.  
1. Place the probe in a liquid and wait for the temperature reading  
to stabilize.  
2. Enter the actual temperature of the liquid (the current reading is shown for  
reference). Temperature calibration is complete.

This option couples the sampler to an external, 3-watt, cellular phone. The  
cellular phone is mounted in a NEMA 4X enclosure and is powered through  
the sampler by the sampler power supply. Enabling Modem Power also  
provides power to the Cellular Communication via a connector cable.  
communications between the  
sampler and the host computer, it is  
required that the host computer is  
equipped with a Cellular Compatible  
modem, it must support the  
MNP.10EC protocol. Computers  
equipped with modems that do not  
support this protocol are able to  
connect to the sampler but will not  
be able to maintain a reliable  
connection.  
The cellular phone is set to activate upon an alarm. Additionally, the end user  
can use the phone to make cellular voice calls directly from the installation site  
as needed.  
Site Selection  
The quality and availability of cellular service varies considerably from one  
geographical location and from day to day. Factors that affect the quality of  
cellular service include but are not limited to: weather, time of day, distance to  
the nearest cell tower, other cellular traffic, etc.  
Installation and Setup  
Note: If the display on the cell  
phone is not present, check to make  
sure the cell phone power is  
enabled in the setup of the sampler.  
Also check to make sure that the  
sampler is connected to a power  
source and is turned on.  
1. Connect the four conductor cable between the four pin connector on the  
side of the cellular phone housing and to the connector in the side of the  
sampler case labeled MODEM. This cable supplies both the data and the  
12 V dc power for the cell modem.  
2. Attach the magnetic base cell phone antenna to any flat metal object in  
the immediate area. For optimum performance, mount the antenna in a  
vertical position.  
Note: Mount the antenna as high and as far away from the sampler as possible. RF  
power radiated during transmission by the cell phone antenna in close proximity to  
the sampler may have adverse affects on data measurements.  
3. When necessary, reposition the antenna to obtain optimum signal  
strength.

4. Loosen the four screws on the cover of the cell phone enclosure and  
remove the cover, to view the signal strength. The signal strength is  
indicated by the number of dashes across the bottom of the cell phone  
display. The more dashes the greater the signal.  
6.2.2.2 Reliable Communications  
In order to ensure reliable communications between the sampler and the host  
computer, it is absolutely essential that the host computer is equipped with a  
Cellular Compatible modem. The modem on the host computer must support  
the “MNP.10ED” protocol. Computers equipped with modems that do not  
support this protocol may be able to connect to the sampler but will not be  
able to maintain reliable connections.  
6.2.2.3 Cellular Modem Scheduling  
With Cellular Modem Scheduling enabled, both the modem and cell phone  
power will simultaneously be turned off and on at user defined intervals to  
conserve battery power. If Cellular Modem Scheduling is disabled the sampler  
will assume that a land line is available and that the cell phone is not  
connected to the sampler. With Cellular Modem Scheduling disabled (and the  
sampler on battery power) the sampler will leave the modem turned off until a  
call is received on the land line.  
Note: If the Cellular Modem  
Scheduling is disabled and the  
sampler is connected to a cell  
phone rather than a land line, the  
sampler will not be able to answer  
any incoming calls.  
If the sampler is on ac power or the battery voltage is over 14.5 volts, the  
power to both the cell phone and modem will constantly be on regardless of  
whether Cellular Modem Scheduling is enabled or not.  
If the sampler is configured to call a pager for alarms and the alarm condition  
is met, the sampler will still call the pager even if modem scheduling is  
disabled. In this situation the cell phone and modem will temporally be  
powered back up again to allow the sampler to call the pager and transmit the  
alarm code. However, as soon as the alarm code is transmitted, the power to  
the cell phone and modem will again be turned off.  
Note: If Modem Power is disabled,  
the Cellular Modem Scheduling  
prompt will not appear.

6.3.3 4–20 mA Calibration  
After wiring the 4–20 mA connection perform a 4–20 mA output calibration.  
The 4–20 mA output calibration requires a digital multimeter or access to the  
4–20 mA current loop wiring. Two 4–20 mA outputs are available and are  
designated Output A and Output B. Both outputs are calibrated the same way  
and are isolated from each other.  
Calibration may be performed while the 4–20 mA device is in the current loop,  
as shown in Figure 24 or disconnected from the current loop as shown in  
Figure 25. In either case, the multimeter must be set to a 20 milliamp dc range  
or greater.  
1. From the Main Menu, select OPTIONS > ADVANCED OPTIONS >  
CALIBRATION > 4–20 mA OUTPUTS.  
2. Connect a multimeter to the 4–20 mA current outputs per Figure 24 and  
Figure 25.  
3. Make sure that the 4–20 mA output is enabled. If it is not enabled, press  
CHANGE CHOICE so that the display shows Enabled and press ACCEPT.  
4. Select the output (A or B) to calibrate.  
5. Press any key to set the selected output to 4.00 mA dc.  
6. Measure the current on the selected output using the multimeter and  
enter the measured value using the numeric keypad. Press ACCEPT.

6.4 Alarm Relays  
Note: Current to the relay contacts  
must be limited to 5 amps. A means  
to remove power from the relays  
locally in case of an emergency or  
for servicing the product must be  
provided by the user. This can be  
accomplished with an external  
switch and a 5-amp fuse or with a  
switched 5-amp circuit breaker.  
Four alarm relay outputs are available as a factory installed option. The relays  
are mounted in an external NEMA 4X enclosure for installation to a wall or  
panel. Alarm contacts are rated for 10 amps at 240 V ac (resistive load).  
The alarm wiring can be sized according to the load being used. The relay  
connector will accept wire sizes from 18–12 AWG with a rating of 300 V, 80 °C  
minimum. Do not use wire smaller than 18 AWG.  
For relay pin assignments refer to Table 17 and Figure 26.

6.4.2 Alarm Relays Programming  
Program alarms activate based on certain conditions (low battery, low  
memory, etc.). When an alarm is tripped, an action is initiated (report via  
modem, dial a pager, or set a relay). There are two types of alarms: Trouble  
Alarms and Set Point Alarms.  
6.4.2.1 Trouble Alarms  
Trouble Alarms initiate an action when a trouble condition occurs. For  
example, a relay may close when the memory is full. Refer to Troubleshooting  
and Error Messages on page 127 for more information on trouble alarms.  
1. From the Main Menu, select SETUP > ADVANCED OPTIONS > ALARMS.  
2. Select one of the trouble conditions.  
3. Select an action to occur when the alarm is activated. The table below  
lists each Trouble Condition. Refer to Appendix C on page 127 for causes  
and solutions.

6.4.2.2 Set Point Alarms  
Set Point Alarms look for trip points to be reached (either high or low or both)  
before initiating an action. For example an initiated action may be the closing  
of a relay when the water level exceeds 60 cm (24 in.) or drops below 10 cm  
(4 in.) Set Point Alarms activate when a user-definable high and/or low set  
point is reached.

Section 6  
1. Enable one of the alarm conditions.  
2. Select an action to occur when the alarm is activated.  
3. Set either a High trip point or a Low trip point.  
4. After entering the trip point enter the deadband value. The deadband is  
the area between the alarm “turn on” and “turn off.”  
Note: Log rainfall to use an alarm on a rainfall condition; likewise, log flow in order to  
implement an alarm on a flow rate of change.

Note: Rainfall and Flow Rate of Change alarms are HIGH set point conditions; they  
take no deadband and they are time dependant.  
Deadband  
After entering the trip point, enter a deadband value. The deadband is the  
area between alarm “turn-on” and “turn-off”.  
The purpose of setting the deadband is to eliminate alarm chatter which may  
occur if the “turn-on” and “turn-off” values are too close together. Small  
fluctuations occurring when the reading is at or near the trip point can rapidly  
toggle an alarm relay on and off.  
In the pH example (Figure 28) the deadband is set to 0.10 pH. When the pH  
reached 6.9 (lower dashed line), the alarm tripped, but the alarm did not turn  
off until the pH came back up to 7.00. This difference is the deadband setting  
which should be set according to the characteristics of the item  
being measured.

6.5 Analog Inputs  
6.5.1 Analog Inputs Connection  
Note: 4–20 mA inputs must be  
isolated. Maximum load per unit is  
200 ohms.  
Analog voltage as well as analog current input signals are accommodated in a  
single connector.  
To connect the analog voltage signal (-4.0 to +4.0 V dc):  
1. Tie ground wire to Pin B (ground).  
2. Tie analog voltage wire to the appropriate voltage input pin  
(Pin C, E, or G).  
For example, to connect an analog voltage input to analog input channel 1, tie  
the ground wire to pin B and your positive wire to pin C.  
To connect an analog current signal (4–20 mA dc)  
1. Tie ground wire to Pin B (ground).  
2. Connect analog current wire to both voltage and current input pins for the  
appropriate channel (Pin C and D, or E and F, or G and H).

Section 6  
There are a total of three analog input channels available on the sampler.  
These inputs accept 4–20 mA dc or -4.0 to +4.0 V dc analog signals. They  
can be logged and graphed and can also be used to trigger alarms, cause  
setpoint samples, and control 4–20 mA outputs.  
6.5.2 Analog Inputs Programming  
Analog input channels can accept a signal from an external device. This  
signal may range from -4.0 V dc (min) to +4.0 V dc (max) or from 4 to 20 mA  
dc depending on the input selected. In some cases, input signals from certain  
devices may also fall somewhere within those ranges. For that reason, each  
analog input channel must be mapped to the minimum and maximum signal  
limits of the external device.  
To map an external device to an analog input channel:  
1. From the Main Menu, select OPTIONS>ADVANCED OPTIONS>DATALOG.  
2. Highlight Select Inputs using the UP and DOWN keys and press SELECT.  
3. Highlight the analog channel to log using the UP and DOWN keys, then  
press SELECT.  
Note: If logging is enabled on any  
channel, then that channel will have  
an arrow in front of the channel  
name to signify the channel  
is logged.  
4. Press CHANGE CHOICE to cycle between Logged and Not Logged, then  
press ACCEPT.  
5. Enter a Logging Interval using the numeric keypad. Press ACCEPT to  
continue.  
6. Select Unit of measurement (ppm, ppb, afd, cfs, cfm, cfd, cms, cmm, cmh,  
cmd, gps, gpm, gph, lps, lpm, lph, or mgd).  
7. Enter Low Point.  
8. Enter High Point.  
9. Select another channel to configure, or press RETURN to back up one  
step. Press MAIN MENU to return to the Main Menu display.

7.1 Cleaning the Sampler  
7.1.1 Cleaning the Sampler Cabinet  
Clean the interior and exterior of the sampler cabinet with a damp sponge and  
mild detergent. Do not use abrasive cleaners.  
7.1.2 Cleaning the Sample Bottles  
Clean the bottles using a brush and water with a mild detergent, followed by a  
fresh water rinse and a distilled water rinse. Glass bottles may also be  
autoclaved.  
7.1.3 Cleaning the Intake Tubing and Pump Tubing  
Clean the tubing by pumping water with mild detergent or other cleaning  
solution through the tubing, using the peristaltic pump in Manual Pump Mode.  
Press MANUAL MODE.  
7.1.4 No Lubrication Required  
The sampler does not require routine lubrication. Do not lubricate the pump  
tube with petroleum jelly, silicone grease, oil, or any other lubricant, as this will  
substantially reduce the life of the pump tube and roller assembly.  
7.2  
Pump Tubing Maintenance  
DANGER  
DANGER  
Always disconnect power to the  
sampler before removing the  
pump cover.  
Débranchez toujours l'alimentation de l'analyseur d'echantillonneur avant de  
déposer le couvercle de la pompe.  
Replacement pump tubing is available from the manufacturer in 15' bulk  
length (Cat. No. 4600-15), and 50' bulk length (Cat. No. 4600-50). Use of  
tubing other than that supplied by the manufacturer may cause excessive  
wear on mechanical parts and/or poor pump performance.  
7.2.1 Tubing Life Estimates  
Pump tubing life depends on several factors:  
•
Distance from sample source. Locate the sampler as close to the sample  
source as possible.  
•
•
Vertical lift. Minimize the vertical lift (ideally, 15 feet or less).  
Intake Rinses. Minimize the number of intake rinses prior to  
sample collection.  
•
•
Pump roller assembly condition. Remove (clean) the silicone residue in  
the interior of the pump housing and on the rollers before installing a  
new tube.  
Constituents in the sample liquid. Grit and other abrasive solids  
cause greater wear on the tubing as they are squeezed through the  
pump rollers.

Section 7  
Note: To extend the life of the  
tubing, rotate the pump tube 90  
degrees in the pump housing after  
approximately 2/3 of the life has  
been realized (once the tube life has  
been determined through use).  
Experience at a particular site will be your best indicator of tubing life. Visually  
inspect the tubing and rollers on a regular basis after initial installation to get a  
feel for what maintenance your site will require. Be sure to replace the pump  
tubing before it splits to prolong the life of the sampler and keep the work area  
free of contamination from the sample liquid.  
The proper length of silicone tubing must be used in the pump body. An  
improper length can reduce the life of the tubing and pump rollers. Refer to  
Figure 29 for the correct length.

1. To replace the pump tube, remove the four screws on the pump cover.  
2. Remove the front cover of the pump housing.  
3. Remove the existing tubing. Locate the black dot on the new tubing. The  
end of the tube that extends farthest beyond the black dot attaches to the  
stainless steel tubing connector.  
4. Install the pump tube in the pump housing until the black dots are visible  
just outside the pump body.  
5. After inserting the new pump tube, reinstall the front cover and secure it  
with the four screws until finger tight.  
7.3 Upgrades, Repairs, General Maintenance  
Only a qualified technician should service the sampler. For example, steps  
that require knowledge of CMOS electrostatic discharge precautions and  
advanced electronics training and should only be performed by a qualified  
technician. If you need assistance in performing any of the following service  
steps, contact the manufacturer.

Section 7  
Electrostatic Discharge (ESD) Considerations  
To minimize ESD risks,  
maintenance procedures not  
requiring power to the sampler  
should be performed with power  
removed.  
Delicate internal electronic components can be damaged by static electricity,  
resulting in degraded instrument performance or eventual failure.  
The manufacturer recommends taking the following steps to prevent ESD  
damage to your instrument:  
•
Before touching any instrument electronic components (such as  
printed circuit cards and the components on them) discharge static  
electricity from your body. This can be accomplished by touching an  
earth-grounded metal surface such as the chassis of an instrument,  
or a metal conduit or pipe.  
•
•
To reduce static build-up, avoid excessive movement. Transport  
static-sensitive components in anti-static containers or packaging.  
To discharge static electricity from your body and keep it discharged, wear  
a wrist strap connected by a wire to earth ground.  
Handle all static-sensitive components in a static-safe area. If possible, use  
anti-static floor pads and work bench pads.  
7.4 Internal Maintenance Items  
The following items require access to the inside of the case for service:  
•
•
•
•
•
Fuses for the RS485 and analog interface connectors (if equipped)  
Internal desiccant module  
RAM memory batteries  
System upgrades (4–20 mA, modem, alarm relays, etc.)  
Circuit board repair

Section 7  
To open the controller:  
1. Remove the 17 screws from around the perimeter of the controller  
back panel.  
2. Carefully pull open the bottom panel and let the attached connectors  
swing out of the way.  
3. If necessary for the repair being performed, unplug the appropriate  
connectors. Always note each connector location before unplugging  
anything. Re-installing a plug into the wrong connector can cause  
extensive damage.  
Note: The front panel gasket has a light coating of grease to help ensure a watertight  
seal. Do not contaminate the grease or gasket area with dirt or debris during  
servicing. Always replace the gasket if it is damaged or missing. Never  
reassemble the case without the gasket properly installed.  
7.6 Re-installing the Bottom Panel  
Note: Always follow the procedure  
below when re-installing the  
sampler bottom panel. Improper  
panel installation may result in  
damage to  
1. Hand tighten each nut until it makes contact with the panel.  
2. Tighten the nuts in sequence shown in Figure 30 to 5 in.-lb (0.56 N-m).  
3. Repeat the tightening procedure in the same sequence to 10 in.-lb  
the instrument.  
(1.13 N-m).

7.7 Circuit Board Identification  
There are two main circuit boards in the sampler; the Utility Board and the  
CPU board. The CPU board is attached to the bottom panel and the Utility  
board is located inside the control housing behind the motor/gearbox  
assembly.  
Note: Removal and handling of the circuit boards used in the sampler requires  
knowledge of ESD (Electro-Static Discharge) precautions and the CMOS  
(Complementary Metal-Oxide Semiconductor) circuit components used in the  
sampler. Static electricity has the potential to damage the CMOS components of  
the sampler when the boards are unplugged and removed from the case.  
Precautions must be taken to assure static-free personnel and work area prior to  
handling the circuit boards.

Replacing the Fuse  
DANGER  
PELIGRO  
For continued protection  
against fire, replace fuses with  
only fuses of specified type and  
current rating.  
Para una continua protección contra incendios, reemplace los fusibles  
únicamente por los del tipo y capacidad recomendados.  
Medium Delay Fuse, 5 Amp  
The main 12 volt line is fused as soon as it enters the controller housing. This  
is a 5-amp medium delay fuse (Cat. No. 8753) and is accessible from outside  
the case on the back side of the controller housing. To remove the fuse  
unscrew the cap on the fuse holder with a flat blade screwdriver.  
PCB Fuse Removal and Inspection  
Pull the fuse straight out of the holding clips to remove the fuse. The wire  
strand inside the glass tube will be broken. Use an ohmmeter to tell for sure if  
a fuse needs to be replaced.  
7.9 Motor/Gear Box  
The motor/gear box requires no regular maintenance. The special formulation  
gears are self lubricating and require no oil or grease.  
7.10 Internal Desiccant Module  
Note: The desiccant module cannot  
be recharged by heating. Do not  
attempt to bake the desiccant  
module in an oven to remove the  
moisture as this could be a fire  
hazard.  
The Internal Desiccant Module (Cat. No. 8849) consists of a  
moisture-absorbent material inside a poly bag. If the humidity indicator on the  
front panel turns pink, replace the module and the back panel perimeter  
gasket (Cat. No. 8606). The desiccant module is located under the CPU  
board.  
7.10.1 Replacing the Desiccant  
To replace the desiccant, detach the controller from the refrigerator cabinet,  
and remove the screws from the controller bottom panel. Remove the  
desiccant bag and replace with a new one. Replace the controller gasket and  
cover plate. Reattach the controller to the refrigerator. After replacing the  
desiccant module and re-sealing the case, the Internal Case Humidity  
Indicator Disc (Cat. No. 2660) should return to its original blue color. If the  
humidity indicator is blue the desiccant is dry. Replace the indicator disc if it  
fails to return to blue after replacing the desiccant module. To replace the  
indicator disc, remove the bottom panel that is held in place by a small clip  
and screw.

Section 7  
7.11 Memory Battery  
Random Access Memory (RAM) is a very reliable data storage medium for  
microprocessor applications. However, RAM requires power at all times. If  
power is removed, the data stored in the RAM chip is lost. Therefore, RAM  
chips cannot be powered from the sampler power supply because data and  
program settings would be lost every time the power cord was unplugged. A  
separate battery located inside the sampler controller is provided to power the  
RAM chips and the real-time clock. The memory battery keeps the program  
entries and logged sample data alive inside the RAM memory when the main  
power fails or is removed for transport or replacement.  
The sampler memory battery consists of two “C” cell alkaline batteries.  
Should the memory battery voltage fall too low to properly maintain the  
program settings, a warning: MEMORY POWER LOW will alert to replace the  
battery. The sampler utilizes a very small amount of energy from the memory  
battery during normal operation. The service life of the batteries in this  
application is typically five years.

Graph Manipulation  
Table 23 Graphing Functions and Descriptions  
Functions Description  
Status Bar  
Displays the time, date, measured value, and unit of measure at the intersection of the data cursor. Placing the  
cursor’s data on the status bar eliminates the need for X or Y axis labels and provides a larger graph viewing  
area.  
Moving the Data Cursor with the Arrow Keys  
The data cursor appears as a vertical line in the center of the graph. Move the data cursor to the left or right by  
using the soft keys or the numeric keypad.  
Moving the Data Cursor with the Numeric Keypad  
The keys 0–9 represent a percentage of full scale. Pressing a numeric key on the keypad while a graph is  
displayed causes the data cursor to jump to the location on the graph that is represented by that key.  
For example, pressing the 0 key moves the data cursor to the far left end or 0% position on the graph. Pressing  
the 5 key moves the data cursor to the middle or 50% position of the graph. Pressing the 9 key moves the cursor  
to the 90% position.  
Next Channel Soft Key  
Graphs data from the next logged channel. For example, if the sampler is logging Level, Flow, and pH and the  
Level graph is currently displayed, the NEXT CHANNEL key causes the Flow channel to be graphed. Pressing  
Next Channel again will create a graph for pH channel. Pressing NEXT CHANNEL again returns to the Level  
graph, selects a time period of interest, and compares different graphs.  
Graphic Display Averaging  
The sampler can display a graph that consists of a maximum of 180 individual  
dots. Since a 24-hour period could contain as many as 1440 data points  
(assuming a one-minute recording interval, one reading each minute) it would  
be impossible to plot every data point on the graph.  
When more than three hours (more than 180 minutes worth) of data is  
graphed, the data points must be averaged. When graphing a partial day of  
three hours or less, all data points are graphed with no averaging.  
When viewing a graph with more than 180 data point, zoom in to the area of  
interest (using the Graph Partial Day option) before all of the individual data  
points are displayed.  
Sample History  
Sample History displays a running history of the sampling program. Displays  
include sampler number, date and time of each sample, the bottle number it  
was put in, and the results of the sample cycle. Result messages include:

Volume Calibration  
From the Main Menu, select OPTIONS> VOLUME CALIBRATION.  
The liquid sensor on the sampler offers unparalleled sample accuracy and  
repeatability. For most site conditions, no volume calibration is necessary, and  
the volume collected is accurate within 10% of the requested volume. To  
improve volume accuracy to 5%, or when sample volume accuracy is  
adversely affected by unusual site conditions (such as the sample source  
located higher than the sampler pump), or when the liquid sensor is disabled,  
then volume calibration should be performed.  
Sensor Disabled  
When the sensor is disabled, you must calibrate the sample volume(s). If  
more than one volume is programmed (such as when using storm water or  
upset sampling), you must calibrate each volume independently (see chart  
below).

7. If the pumped sample volume is correct, press DONE. If not, repeat the  
calibration cycle by pressing TRY AGAIN.  
8. When finished, re-install the pump tube onto the sample fitting.  
Note: To check the sample size after calibration use the Manual Mode function key to  
take a grab sample. Do not go back into calibration to check the volume since the  
volume compensation is reset to zero at the start of a calibration.  
If one or more Timed Rinses are selected (sensor disabled), then they must  
be calibrated as well. The Timed Rinse will rinse the intake line up to 3 times  
prior to taking a sample.

Appendix B  
Data Log  
From the Main Menu, select SETUP > ADVANCED OPTIONS > DATALOG.  
The sampler can record up to 116,000 readings from any or all input channels  
and store them in solid state, battery-backed memory for later viewing or  
retrieval.  
This option allows the selection of channels to log, how often to log, and how  
to treat the memory when it becomes full (Slate or Wrap).  
The sampler has two data logging modes:  
•
•
Power Save Mode  
Continuous Mode  
Logging Intervals  
Logging Intervals are designed to optimize the available memory so that  
readings can be logged for a longer period of time. A logging interval is the  
time period over which readings are taken and then averaged.  
Power Save Mode  
Power Save Mode is automatically initiated upon power-up if a battery is  
installed on the sampler. When operating in Power Save Mode, the sampler  
microprocessor spends most of its time asleep conserving battery power.  
Once per minute, the sampler wakes up, logs the readings from all enabled  
input channels, performs any other necessary functions and then goes back  
to sleep.  
Selecting a five-minute logging interval means that the readings are still taken  
every minute but the data is not logged until the five-minute logging interval is  
complete. At that time the readings are averaged over the previous five  
minutes and that average is logged  
Continuous Mode  
Continuous Mode is automatically initiated upon power up if ac power is  
supplied. The microprocessor stays awake at all times taking readings every  
second. At the end of the specified logging interval, the readings are averaged  
over the previous interval and stored in memory. If a one-minute logging  
interval is selected, a reading will be taken approximately every second but no  
data is logged until the logging interval ends. At that time, the readings are  
averaged over the logging interval and only the average is logged.  
If a five-minute logging interval is selected, readings are still taken every  
second but the data are not logged until the five-minute logging interval ends.  
At that time, the readings are averaged over the previous five minutes and the  
average is logged.  
Extended Power Mode  
Extended Power Mode provides additional battery life by keeping a sampler  
powered down during the entire logging interval. For example, if a logging  
interval of five minutes is selected, the sampler stays asleep until the five  
minutes has expired. It then wakes up, takes a reading, logs it in memory and  
goes back to sleep for another five minutes. The sampler does not wake up  
every minute as it does in normal

Appendix B  
Power Save Mode.  
Selecting a five minute logging interval in Extended Power Mode causes a  
reading to be taken and logged every five minutes. All channels must share  
the same logging interval.  
Note: The Review All Items  
Longer logging intervals result in a longer total recording time. Lower  
resolution also occurs since more averaging is done at higher logging  
intervals. Choose the shortest logging interval possible, while still making data  
collection convenient. If possible, visit the site once per month to collect data,  
and choose a logging interval that almost fills memory over the course of  
one month.  
selection from the Setup menu  
indicates the maximum available  
logging hours for the channels and  
recording intervals you selected.  
The sampler calculates this  
information when the program is run  
using the RUN/STOP key.  
For example, if the sampler is equipped with the standard complement of  
RAM memory (128K) and only one channel is logged, a two-minute logging  
interval would take 24 days to completely fill the available memory  
If, on the other hand, a one-minute logging interval is selected, the memory  
would become full after 12 days.

Dynamic Memory Allocation  
The sampler uses a management scheme called “Dynamic Memory  
Allocation.” All readings are logged in battery-backed Random Access  
Memory (RAM). RAM memory is allocated to each channel dynamically  
during operation. If one channel is logging at five-minute intervals and a  
second channel logging at one-minute intervals, the sampler automatically  
configures memory so that both channels fill memory at the same time. Five  
times as much memory is assigned to the channel that is logging at one-  
minute intervals than the channel that is logging at five-minute intervals.  
Memory can be configured in two ways:  
•
Slate Modem  
•
Wrap Mode

Appendix B  
Slate Memory Mode  
Slate mode causes logging to stop when memory becomes full. The sampler  
continues to operate but no more data is logged. Use this mode to keep data  
from the beginning of the logging period.  
Wrap Memory Mode  
In Wrap mode, when memory becomes full, the oldest reading is discarded  
each time a new reading is taken. When memory becomes full, the sampler  
continues to operate and log data. This mode is best used when interested in  
the most recent data readings.  
Memory Mode Configuration  
To configure the Memory Mode for either Slate mode or Wrap mode:  
1. Select Data Log from the Advanced Options menu.  
2. Select Memory Mode using the UP and DOWN keys, then press ACCEPT.  
3. Press CHANGE CHOICE to choose either Slate or Wrap, then press  
ACCEPT to complete.  
Data Logging Configuration  
To configure the sampler for data logging:  
Note: If logging is enabled on any  
channel, then that channel will have  
an arrow in front of it to signify that  
the channel is logged.  
1. Select Data Log from the Advanced Options menu.  
2. Highlight Select Inputs using the UP and DOWN keys and press SELECT.  
3. Highlight the channel you wish to log using the UP and DOWN keys, then  
press SELECT.  
4. Press CHANGE CHOICE to cycle between Logged and Not Logged, then  
press ACCEPT.  
5. Enter a logging interval using the numeric keypad, then press ACCEPT.  
Valid logging intervals are shown on the status bar along the bottom edge  
of the display for your reference.  
6. Select another channel to configure or press RETURN to back up one step  
or press MAIN MENU to return to the Main Menu display.

Appendix B  
Distributor Test  
The distributor positions the sample tube over the appropriate bottle during  
multiple bottle sampling. If the distributor arm is obstructed or if a problem  
exists with the distributor assembly, the arm will not position over the desired  
bottle correctly.  
This test assumes that 24 bottles are installed which is the most difficult to  
position for the distributor (the most stops and the smallest bottle mouth).  
Upon selecting the Distributor Test, the arm returns to the bottle #1 position  
then moves one bottle at a time for all 24 bottle positions. The arm then  
reverses direction and again stops at all 24 positions on its way back to the  
bottle #1 position. Make sure no obstructions interfere with the distributor  
arm rotation.  
Event List  
The Event List diagnostic provides a time/date stamped list of significant  
events occurring in the sampler. You can review these events to find out when  
an event occurred and what events preceded or followed the event of interest.  
Events may be viewed in chronological order from the beginning or end of the  
event list by selecting View From Start or View From End.  
The event list cannot be erase, even when the program is started. Up to 200  
events are logged before the list wraps around and the oldest entry is  
discarded as each new entry is posted.

Appendix B  
LCD Test  
Display Test allows you to verify that all pixels in the Liquid Crystal Display  
(LCD) are functional. The LCD is made up of 14,400 pixels that are turned on  
and off as needed to create the display of graphics and text. Each individual  
pixel is turned on and off by its own transistor, which means that if a transistor  
failed, the pixel might not turn on, which could cause an unreadable or  
confusing display.  
Selecting LCD Test from the Diagnostics menu will cause the display to  
become black for 3 seconds. This allows verification that all pixels are  
functional. A defective pixel will stand out as a white dot in the field of black  
dots. A message, “The display will remain inverted for 3 seconds” is shown for  
2 seconds followed by a 3 second period with all dots turned on.  
Liquid Sensor  
The liquid sensor contains a high frequency sound transmitter and receiver.  
High frequency sound waves are sent through the silicone pump tubing by  
vibrating a piezo-electric crystal. They are picked up on the other side of the  
tubing by a receiving crystal acting much like a microphone. Since sound  
waves travel much more efficiently through a liquid than they do through air,  
the receiving crystal gets a much louder signal when water passes through  
the tubing in the sensor. The signal from the receiving crystal is converted to a  
voltage which is proportional to the signal strength. This voltage is used by the  
sampler microprocessor to sense the exact moment water reaches the  
sensor. the liquid sensor compares the voltage (signal strength) when the  
tubing is dry (such as when purging the line) to the voltage when the tubing is  
full of water (such as when pumping a sample). The dry verses wet voltage  
reading must be at least 0.8 V dc higher than the 0.3 volts, then when the  
voltage needed to sense liquid would be 1.1 volts or higher.  
The Liquid Sensor is designated as #1. The diagnostic screen displays the  
voltage coming from the sensor electronics. Should a problem arise where the  
liquid sensor is not reliably sensing the liquid, (inaccurate sample volumes,  
water getting to the bottle during an intake rinse, purge failure), use of the  
Liquid Sensor diagnostics values will provide valuable information as to the  
sensor sensitivity.  
Velocity Analysis  
A velocity probe must be installed in the flow stream and be connected to the  
meter in order for this diagnostic to work. This diagnostic allows viewing a  
‘real time’ reading directly from the Submerged Area Velocity Probe. It will  
show the current velocity Signal Strength (percentage of Doppler signal  
returning to the probe) and a ‘real time’ velocity measurement of the flow  
stream. Use this diagnostic to determine if the probe is mounted for optimal  
velocity measurement. The closer to 100% the Signal Strength is, the more  
stable the velocity reading will be. If the signal seems low (50% or less), it may  
be due to improper installation of the probe or a lack of particulate in the flow  
stream.

Appendix B  
Flow Totalizer  
The Flow Totalizer consists of three numeric counters that keep track of the  
total flow being measured. Two software totalizers are standard with a third  
external mechanical totalizer as an option. The two software totalizers consist  
of a resettable totalizer and a non-resettable totalizer. Both totalizers are set  
to zero upon program start.  
Scaling multipliers are provided to allow tailoring of the totalizer response to  
meet the requirements of the application. Some applications with high flow  
rates will require a high scaling factor, while low flow rates will require a low  
scaling factor.  
The scaling factor is displayed whenever a total flow number is displayed.  
As indicated in the Status Screen below, the total flow is displayed as  
“TOTAL (x1000): 465 gal.” Multiplying the displayed total flow by the scaling  
factor (1000) gives an actual total flow of 465,000 gallons.

Appendix D  
How to Calculate Pulses/Counts  
The sampler is equipped to receive either a momentary dry contact closure or  
a +5 to +12 V dc pulse from a flow meter, where each pulse represents a  
known flow increment.  
For example, if the flow meter is set to send a flow pulse for every  
1000 gallons of measured flow and the sampler can count 1 to 9,999 flow  
pulses between sample intervals, you can program the sampler to receive  
10 pulses between samples to take one sample for every 10,000 gallons of  
liquid flow.  
To determine the number of flow pulses between sample intervals, you must  
determine the total number of samples (represented by n in the following  
examples) to be collected, and the period of time over which they are to be  
collected. You must also know the total flow, Q, during the sampling program.  
The following two-step method should be useful for determining the value for  
INTV = _ _ _ _ CNTS during setup.  
1. Determine f, where f represents the flow increment between samples and  
n represents the total number of samples to be collected.  
Q
f = ----  
n
2. Multiply the flow increment between samples, f, by the pulse frequency  
output of the flow meter (i.e. 1 pulse per 100 gallons, 1 pulse per  
1000 gallons, etc.). If the pulse frequency output of the flow meter is not  
known, consult the flow meter manufacturer.  
Note: The final result is not necessarily a whole number. You must round off the result  
to the nearest whole number.  
Flow-Proportional Sampling Intervals - Using External Pulses  
Hach samplers are equipped to receive either a momentary dry contact  
closure or +5 to +12 V dc pulse from a flow meter, where each pulse  
represents a known flow increment.  
Example 1  
You want to collect 35 samples over a 24-hour period. The total expected flow  
over this period is 235,000 gallons. The flow meter pulse frequency is  
one pulse for every 100 gallons.  
1. Determine the flow increment between samples:  
Q
n
235,000 gallons  
35 samples  
f = ---- = ----------------------------------------- = 6,714 gallons/sample  
2. Multiply the flow increment, f, by the pulse frequency output of the  
flow meter.  
1 pulse  
100 gallons  
------------------------------  
6,714 gallons/sample ×  
= 67.14 pulse/sample  
Therefore, the value for INTV = _ _ _ _ CNTS is 67.  
(67.14 is rounded off to 67.)  
Example 2  
You want to collect 24 samples over an 8-hour period. The total expected flow  
over this 8-hour period is 85,000 gallons. The flow meter pulse frequency  
output is one pulse for every 50 gallons.

2. Multiply the flow increment, f, by the pulse frequency output of the flow  
meter.  
1 pulse  
50 gallons  
---------------------------  
3,542 gallons/sample ×  
= 70.84 pulse/sample  
Therefore, the value for INTV = _ _ _ _ CNTS is 71.  
Example 3  
You want to collect 48 samples over a 16-hour period. The total expected flow  
over this period is 1,750,000 gallons. The flow meter pulse frequency output is  
one pulse for every 1,000 gallons.  
1. Determine the flow increment between samples:  
Q
n
1,750,000 gallons  
f = ---- = ---------------------------------------------- = 36,458 gallons/sample  
48 samples  
2. Multiply the flow increment, f, by the pulse frequency output of the flow  
meter.  
1 pulse  
1,000 gallons  
-----------------------------------  
36,458 gallons/sample ×  
= 36.458 pulses/sample  
Therefore, the value for INTV = _ _ _ _ CNTS is 36.  
Flow Proportional Sampling, External—Using 4–20 mA Signal Converted to Pulses, Flow Signal Interface  
The Flow Signal Interface (Cat. No. 2021) is an optional 4–20 mA interface  
that converts 4–20 mA current signals (from a flow meter) to 12 V dc pulses.  
At 20 mA, the interface transmits 10 12-volt pulses per minute. As the current  
signal decreases, the 12 V pulses decrease proportionally. Typically, users  
collect a certain number of samples over a given period of time when  
sampling in proportion to the flow rate.  
To calculate the number of 12 V dc output pulses between samples,  
determine the total number of samples (represented by n in the following  
examples) that you want to collect, and the period of time over which you want  
to collect them. Use the three-step method presented below to determine the  
“Total Count” value that you will enter while programming the Setup section of  
the sampler.  
1. Calculate Q, where Q is the average flow rate (during the sampling  
program) divided by the maximum flow rate. (The maximum flow rate  
corresponds to the 20 mA output of the flow meter.)  
2. Calculate t, where t is defined as a/n; n is the total number of samples  
collected over a given period of time; and a represents time in minutes,  
over which n samples are collected.  
3. Multiply Q x t x 10. Enter the result in the programming step:  
INTV = _ _ _ _ CNTS.  
Note: The product of Q x t x 10 is not necessarily a whole number. You must round off  
the result to the nearest whole number.

Appendix D  
Use the following examples to help you determine the value that you need to  
enter when programming for sampling based on counts.  
Example 1  
You want to collect 24 samples over a 24-hour period on a 4–20 mA flow  
proportional basis.  
Average Flow Rate = 3.5 mgd (average flow rate over the 24-hour period)  
Maximum Flow Rate = 10 mgd  
a = 1440 minutes  
1. Calculate Q.  
Average Flow Rate  
Maximum Flow Rate 10 mgd  
3.5 mgd  
Q = ------------------------------------------------------ = --------------------- = 0.35 mgd  
2. Calculate t.  
a
n
1440 min  
t = -- = ------------------------------ = 60 min/sample  
24 samples  
3. Multiply Q x t x 10.  
0.35 mgd × 60 min/sample × 10 = 210  
Therefore, the value entered for INTV = _ _ _ _ CNTS is 210.  
Example 2  
You want to collect 48 samples over a 24-hour period on a 4–20 mA flow  
proportional basis.  
Average Flow Rate = 1.75 mgd (average flow rate over the 24-hour period)  
Maximum Flow Rate = 3 mgd  
a = 1440 minutes  
1. Calculate Q.  
Average Flow Rate  
Maximum Flow Rate 3 mgd  
1.75 mgd  
Q = ------------------------------------------------------ = ------------------------ = 0.583 mgd  
2. Calculate t.  
a
n
1440 min  
t = -- = ------------------------------ = 30 min/sample  
48 samples  
3. Multiply Q x t x 10.  
0.583 mgd × 30 min/sample × 10 = 174.9  
Therefore, the value entered for INTV = _ _ _ _ CNTS is 175.  
Example 3  
You want to collect 96 samples over a 24-hour period on a 4–20 mA flow  
proportional basis.  
Average Flow Rate = 0.52 mgd (average flow rate over the 24-hour period)  
Maximum Flow Rate = 2 mgd  
a = 1440 minutes  
1. Calculate Q.  
Average Flow Rate  
Maximum Flow Rate 2.0 mgd  
0.52 mgd  
Q = ------------------------------------------------------ = ------------------------ = 0.26 mgd

Appendix D  
2. Calculate t.  
a
n
1440 min  
t = -- = ------------------------------ = 15 min/sample  
96 samples  
3. Multiply Q x t x 10.  
0.26 mgd × 15 min/sample × 10 = 39  
Therefore, the value entered for INTV = _ _ _ _ CNTS is 39.  
Example 4  
You want to collect 32 samples over an 8-hour period.  
Average Flow Rate = 70 gpm (average flow rate over the 8-hour period)  
Maximum Flow Rate = 210 gpm  
a = 480 minutes  
1. Calculate Q.  
Average Flow Rate  
Maximum Flow Rate 210 gpm  
70 gpm  
Q = ------------------------------------------------------ = ---------------------- = 0.33 gpm  
2. Calculate t.  
a
n
480 min  
t = -- = ------------------------------ = 15 min/sample  
32 samples  
3. Multiply Q x t x 10.  
0.33 mgd × 15 min/sample × 10 = 49.5  
Therefore, the value entered for INTV = _ _ _ _ CNTS is 50.  
Example 5  
It is desired to collect 30 samples over a 2-day period.  
Average Flow Rate = 0.25 cfs (average flow rate over the 48-hour period)  
Maximum Flow Rate = 1 cfs  
a = 2,880 minutes  
1. Calculate Q.  
Average Flow Rate  
Maximum Flow Rate 1 cfs  
0.25 cfs  
Q = ------------------------------------------------------ = -------------------- = 0.25 cfs  
2. Calculate t.  
a
n
2,880 min  
t = -- = ------------------------------ = 96 min/sample  
30 samples  
3. Multiply Q x t x 10.  
0.25 cfs × 96 min/sample × 10 = 240  
Therefore, the value entered for INTV = _ _ _ _ CNTS is 240.  
You will notice from the previous five examples that the average and  
maximum flow rate can be expressed in any units, i.e. mgd, gpm, cfs, etc.  
However, express the average and maximum flow rate in the same units for  
any given situation.
