1. INTRODUCTION, FEATUERES, AND OPTIONS
1.1. T803 OVERVIEW
The Model T803 Carbon Dioxide/Oxygen Analyzer (T803 CO2/O2 Analyzer) is
a microprocessor-controlled analyzer that determines the concentration of
molecular carbon dioxide (CO2) and oxygen (O2) in the sample gas drawn
through the instrument. It uses infrared absorption to measure CO2 concentration
and paramagnetic technology to measure O2 concentration.
The Model T803 analyzer’s multi-tasking software gives the ability to track and
report a large number of operational parameters in real time. These readings are
compared to diagnostic limits kept in the analyzer’s memory where, should any
fall outside of those limits, the analyzer issues automatic warnings.
Built-in data acquisition capability using the analyzer's internal memory, allows
the logging of multiple parameters including averaged or instantaneous
concentration values, calibration data, and operating parameters such as pressure
and flow rate. Stored data are easily retrieved through the serial port or Ethernet
port via our APICOM software or from the front panel, allowing operators to
perform predictive diagnostics and enhanced data analysis by tracking parameter
trends. Multiple averaging periods of one minute to 365 days are available for
over a period of one year.

HAZARD
OXYGEN IS A STRONG OXIDIZER.
This is a general purpose instrument designed for usage in nonhazardous areas.
Ensure that all safety precautions related combustible gases are followed.
Before working with the casing open, be sure to turn off power to the analyzer, and
perform air or N2 gas purging of not only the analyzer inside, but also the sample gas
line.
In addition, carefully prevent oil and grease from adhering to any tubing. Otherwise,
poisoning, fire or explosion may be caused due to gas leakage, etc.

3.1. UNPACKING THE T803 ANALYZER
CAUTION
GENERAL SAFETY HAZARD
To avoid personal injury, always use two persons to lift and carry the T803.
CAUTION – AVOID WARRANTY INVALIDATION
Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small to
be felt by the human nervous system. Damage resulting from failure to use ESD
protection when working with electronic assemblies will void the instrument warranty.
See A Primer on Electro-Static Discharge in this manual for more information on preventing
ESD damage.
CAUTION!
Do not operate this instrument until removing dust plugs from SAMPLE and EXHAUST
ports on the rear panel!
Note
Teledyne API recommends that you store shipping containers/materials
for future use if/when the instrument should be returned to the factory
for repair and/or calibration service. See Warranty section in this manual
and shipping procedures on our Website at http://www.teledyne-api.com
under Customer Support > Return Authorization.
Verify that there is no apparent external shipping damage. If damage has
occurred, please advise the shipper first, then Teledyne API. Keep the shipping
container/packaging intact for the shipper’s examination.
Included with your analyzer is a printed record of the final performance
characterization performed on your instrument at the factory.

3.3.1.3. ANALOG OUTPUT CONNECTIONS
The T803 is equipped with several analog output channels accessible through the
ANALOG OUT connector on the rear panel of the instrument. The standard
configuration for these outputs is VDC. An optional current loop output is
available for each (Section 3.3.1.4).
When the instrument is in its default configuration, channel A1 outputs a signal
that is proportional to the CO2 concentration of the sample gas. If Dual or Auto
range is configured, channels A1 and A2 each output a signal proportional to the
Channel A3 outputs a signal proportional to the O2 concentration of the sample
gas.

4. Remove the screw holding the current loop option to the motherboard.
5. Disconnect the current loop option PCA from the appropriate connector on
the motherboard (see Figure 3-8).
Each connector, J19, J21 and J23, requires two shunts. Place one shunt on
the two left most pins and the second shunt on the two pins next to it (refer to
Figure 3-8 for an example).
6. Reattach the top case to the analyzer.
7. The analyzer is now ready to have a voltage-sensing, recording device
attached to that output.
3.3.1.5. CONNECTING THE STATUS OUTPUTS
The status outputs report analyzer conditions via optically isolated NPN
transistors, which sink up to 50 mA of DC current. These outputs can be used to
interface with devices that accept logic-level digital inputs, such as programmable
logic controllers (PLCs). Each status bit is an open collector output that can
withstand up to 40 VDC. All of the emitters of these transistors are tied together
and connected at Pin D.
Note
Most PLCs have internal provisions for limiting the current that the input will
draw from an external device. When connecting to a unit that does not have
this feature, an external dropping resistor must be used to limit the current
through the transistor output to less than 50 mA.
At 50 mA, the transistor will drop approximately 1.2V from its collector to
emitter.
The status outputs are accessed via a 12-pin connector on the analyzer’s rear

3.3.1.7. CONCENTRATION ALARM RELAY (OPTION 61)
The Teledyne API T-Series analyzers have an option for four (4) “dry contact”
relays on the rear panel of the instrument. This relay option is different from and
in addition to the “Contact Closures” that come standard on all TAPI instruments.
The relays have three pins that have connections on the rear panel (refer Figure
3-11). They are a Common (C), a Normally Open (NO), and a Normally Closed
(NC) pin.
Figure 3-11:
Concentration Alarm Relay
Alarm 1 “System OK 2”
Alarm 2 “Conc 1”
Alarm 3 “Conc 2”
Alarm 4 “Range Bit”
“ALARM 1” RELAY
Alarm 1 which is “System OK 2” (system OK 1, is the status bit) is in the
energized state when the instrument is “OK” & there are no warnings. If there is
a warning active or if the instrument is put into the “DIAG” mode, Alarm 1 will
change states. This alarm has “reverse logic” meaning that if you put a meter
across the Common & Normally Closed pins on the connector you will find that
it is OPEN when the instrument is OK. This is so that if the instrument should
turn off or lose power, it will change states & you can record this with a data
logger or other recording device.
“ALARM 2” RELAY & “ALARM 3” RELAY
The “Alarm 2 Relay” on the rear panel, is associated with the “Concentration
Alarm 1” set point in the software & the “Alarm 3 Relay” on the rear panel is
associated with the “Concentration Alarm 2” set point in the software.
Alarm 2 Relay
Alarm 3 Relay
CO2 Alarm 1 = xxx %
CO2 Alarm 2 = xxx %
Alarm 2 Relay O2 Alarm 1 = xxx %
Alarm 3 Relay
O2 Alarm 2 = xxx %
The Alarm 2 Relay will be turned on any time the concentration set-point is
exceeded & will return to its normal state when the concentration value goes back
below the concentration set-point.
Even though the relay on the rear panel is a NON-Latching alarm & resets when
the concentration goes back below the alarm set point, the warning on the front
panel of the instrument will remain latched until it is cleared. You can clear the
warning on the front panel by either pushing the CLR button on the front panel or
through the serial port.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
The software for this instrument is flexible enough to allow you to configure the
alarms so that you can have 2 alarm levels for each gas.
CO2 Alarm 1 = 20 %
CO2 Alarm 2 = 100 %
O2 Alarm 1 = 20 %
O2 Alarm 2 = 100 %
In this example, O2 Alarm 1 & CO2 Alarm 1 will both be associated with the
“Alarm 2” relay on the rear panel. This allows you to have multiple alarm levels
for individual gases.
A more likely configuration for this would be to put one gas on the “Alarm 1”
relay and the other gas on the “Alarm 2” relay.
CO2 Alarm 1 = 20 %
CO2 Alarm 2 = Disabled
O2 Alarm 1 = Disabled
O2 Alarm 2 = 80 %
“ALARM 4” RELAY
This relay is connected to the “range bit”. If the instrument is configured for
“Auto Range”, and the instrument goes up into the high range, it will turn this
relay on.
3.3.1.8. COMMUNICATION CONNECTIONS
The T-Series analyzers are equipped with connectors for remote communications
interfaces: Ethernet, USB, RS-232, optional RS-232 Multidrop, and optional RS-
options, 60A through 60D), each type of communication method must be
configured using the SETUP>COMM menu.
ETHERNET CONNECTION
For network or Internet communication with the analyzer, connect an Ethernet
cable from the analyzer’s rear panel Ethernet interface connector to an Ethernet
setup instructions.
USB OPTION CONNECTION
For direct communication between the analyzer and a personal computer (PC),
connect a USB cable between the analyzer and desktop or laptop USB ports. (If
this option is installed, the COM2 port can only be used for RS232 multidrop
communication). USB download is required (Section 6.4).
RS-232 CONNECTION
For RS-232 communications with data terminal equipment (DTE) or with data
either a DB9-female-to-DB25-male cable, Option 60A, or a DB9-female-to-DB9-
female cable, Option 60B) from the analyzer’s rear panel RS-232 port to the
device. Adjust the DCE-DTE switch located on the rear panel (Figure 3-4) to
select DTE or DCE as appropriate (Section 6.1).

When the RS-232 Multidrop option is installed, connection adjustments and
configuration through the menu system are required. This section provides
instructions for the internal connection adjustments, then for external
connections, and ends with instructions for menu-driven configuration.
Note
Because the RS-232 Multidrop option uses both the RS232 and
COM2 DB9 connectors on the analyzer’s rear panel to connect the
chain of instruments, COM2 port is no longer available for separate
RS-232 or RS-485 operation.

COULD DAMAGE INSTRUMENT AND VOID WARRANTY
ATTENTION
Printed Circuit Assemblies (PCAs) are sensitive to electro-static
discharges too small to be felt by the human nervous system. Failure to
use ESD protection when working with electronic assemblies will void
preventing ESD damage.
In each instrument with the Multidrop option there is a shunt jumpering two pins
on the serial Multidrop and LVDS printed circuit assembly (PCA), as shown in
Figure 3-14. This shunt must be removed from all instruments except that
designated as last in the multidrop chain, which must remain terminated. This
requires powering off and opening each instrument and making the following
adjustments:
1. With NO power to the instrument, remove its top cover and lay the rear
panel open for access to the Multidrop/LVDS PCA, which is seated on the
CPU.
2. On the Multidrop/LVDS PCA’s JP2 connector, remove the shunt that jumpers
instrument in the chain where the shunt should remain at Pins 21 22).
3. Check that the following cable connections are made in all instruments

3.3.2. PNEUMATIC CONNECTIONS
CAUTION
GENERAL SAFETY HAZARD: CO2
While CO2 itself is not toxic, in sufficient concentrations it can be an irritant and
an asphyxiant.
Obtain a Material Safety Data Sheet for CO2 and any other hazardous components
of sample and calibration gases, and follow the prescribed safety guidelines.
Do not vent sample gases into the immediate vicinity of the analyzer nor into any
enclosed areas.
CAUTION
GENERAL SAFETY HAZARD: O2
While O2 is itself not toxic, the sample gas measured by, and in some cases the
calibration gases used with the T803 can contain other components that are
hazardous (e.g. NO, NO2, SO2, CO, etc).
Obtain a Material Safety Data Sheet (MSDS) for each such gas. Read and
rigorously follow the safety guidelines described there.
Do not vent sample gases containing hazardous components into enclosed areas.
3.3.2.1. CALIBRATION GASES
3.3.2.2. ZERO GAS
Zero gas is similar in chemical composition to the earth’s atmosphere but
scrubbed of all components that might affect the analyzer’s readings. Teledyne
API recommends using pure N2 when calibrating the zero point of your O2 and
CO2 sensors.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
Getting Started
CAUTION
GENERAL SAFETY HAZARD
Rapid release of pure N2 gas into an enclosed space can displace oxygen, and
therefore represents an asphyxiation hazard. This may happen with few
warning symptoms.
Do not vent calibration gases into enclosed areas.
3.3.2.3. SPAN GAS
Span gas is specifically mixed to match the chemical composition of the type of
gas being measured at near full scale of the desired measurement range. Teledyne
API recommends the following when calibrating the span point of each sensor:
O2 sensor: 21% O2 in N2
CO2 sensor: 16% CO2 in N2
Cylinders of calibrated gas traceable to NIST-Standard Reference Material
specifications (also referred to as SRMs or EPA protocol calibration gases) are
commercially available.
3.3.2.4. INTERFERENTS
Some gases, if present in the sample stream in high concentrations, could
potentially interfere with the analyzer. For example, if the Sample Gas to be
measured contains high levels of nitrogen dioxide (NO2) and/or nitrous oxide
(NO), the gases used for both the zero point calibration and the span calibration
should contain the same components in the same proportion in order to cancel
any interference effects.
3.3.2.5. BASIC PNEUMATIC CONNECTIONS
pneumatic inlets/outlets referred to in this section.
CAUTION
GENERAL SAFETY HAZARD
Sample and calibration gases should only come into contact with Stainless Steel,
PTFE (Teflon) tubing, glass or electroless nickel.
The exhaust from the analyzer’s internal or customer supplied external pump
MUST be vented outside the immediate area or shelter surrounding the instrument.

3.5.1. FUNCTIONAL CHECK
After the analyzer’s components have warmed up for at least 60 minutes, verify
that the software properly supports any hardware options that were installed. For
information on navigating through the analyzer’s software menus, see the menu
trees described in Appendix A.1.
Check to make sure that the analyzer is functioning within allowable operating
parameters. Appendix C includes a list of test functions, viewable from the
analyzer’s front panel, and their expected values. (These functions are also useful
The enclosed Final Test and Validation Data Sheet (PN 068360000) lists these
values before the instrument left the factory. To view the current values of these
parameters, press the front panel button sequence for TEST functions as shown in
Figure 6.2 in Section 6.2. Remember until the unit has completed its warm up
these parameters may not have stabilized.
If your local area network is running a dynamic host configuration protocol
(DHCP) software package, the Ethernet will automatically configure its interface
with your LAN.
However, it is a good idea to check these settings to make sure that the
DHCP has successfully downloaded the appropriate network settings from
your network server (see Section 6.3.1).
If your network is not running DHCP, you will have to configure the analyzer’s
interface manually (see Section 6.3.2).

3.5.2. INITIAL CALIBRATION
To perform the calibration you must have sources for zero air and span gas
available for input into the SAMPLE port on the back of the analyzer. See
The initial calibration should be carried out using the same reporting range set up
as used during the analyzer’s factory calibration. This will allow you to compare
your calibration results to the factory calibration as listed on the Final Test and
Validation Data Sheet.
If both available DAS parameters for a specific gas type are being reported via
the instrument’s analog outputs e.g. CONC1 and CONC2 when the DUAL
range mode is activated, separate calibrations should be carried out for each
parameter.
Use the RNG1 button when calibrating for CONC1 (equivalent to LOW
RANGE).
Use the RNG2 button when calibrating for CONC2 (equivalent to HIGH
RANGE).
The calibration procedures assume:
that the zero point and span gases have been adjusted for known interferents
(Section 3.3.2.4)
that the Calibration gas will be supplied through the SAMPLE port
that the pneumatic setup matches that described in Section 0.
Perform the following outline of procedures for each sensor:
recommend that you perform this initial checkout using the following reporting
range settings:
Mode Setting: SNGL
Analog Output Reporting Range: 16% for CO2 and 20.95% for O2
2. If the Dilution Ratio Option is enabled on your T803, perform the Dilution
Ratio set up as presented in Section 5.4.4
3. Set the expected Span Gas Concentration for CO2 and for O2, as presented
analyzer’s analog output range is set.
The analyzer is now ready for operation.
Note
Once you have completed the above set-up procedures, please fill out the
Quality Questionnaire that was shipped with your unit and return it to
Teledyne API. This information is vital to our efforts in continuously
improving our service and our products. THANK YOU.

5.4. SETUP RNGE: ANALOG OUTPUT REPORTING
RANGE CONFIGURATION
5.4.1. PHYSICAL RANGE VERSUS ANALOG OUTPUT REPORTING
RANGES
Functionally, the T803 analyzers have one hardware PHYSICAL RANGE that is
capable of determining concentrations from 0.00% to 100.00% for O2; CO2 is
variable depending on the exact CO2 sensor.
This architecture improves reliability and accuracy by avoiding the need for
extra, switchable, gain-amplification circuitry. Once properly calibrated, the
analyzer’s front panel will accurately report concentrations along the entire span
of its physical range.
Because many applications use only a small part of the analyzer’s full physical
range, data resolution problems can occur for most analog recording devices. For
example, in a typical application where a T803 is being used to measure
atmospheric O2 concentration, the full scale of expected values is only 21% of the
instrument’s full measurement range. Unmodified, the corresponding output
signal would also be recorded across only 21% of the range of the recording
device.
The T803 analyzers solve this problem by allowing the user to select a scaled
reporting range for the analog outputs that only includes that portion of the
physical range relevant to the specific application.
Only this REPORTING RANGE of the analog outputs is scaled, the physical
range of the analyzer and the readings displayed on the front panel remain
unaltered.
Note
Both the DAS values stored in the CPU’s memory and the concentration
values reported on the front panel are unaffected by the settings chosen for
the reporting range(s) of the instrument.

output voltage or current to match the input requirements of the recorder or
datalogger (See Section 5.10.5).
When the instrument is in its default configuration, channels A1 and A2 (Dual or
Auto range) output a signal proportional to the CO2 concentration of the sample
gas.(See Section 5.4.3).
Channel A3 outputs a signal proportional to the O2 concentration of the sample
gas.

5.4.3. REPORTING RANGE MODES
The T803 provides three analog output range modes to choose from.
Single range (SNGL) mode sets a single maximum range for the analog
output. If single range is selected all three outputs are slaved together and
will represent the same measurement span (e.g. 0-20 %), however their
electronic signal levels may be configured for different ranges (e.g. 0-10
VDC vs. 0-0.1 VDC).
Dual range (DUAL) allows the A1 and A2 outputs to be configured with
different measurement spans as well as separate electronic signal levels.
Auto range (AUTO) mode gives the analyzer the ability to output data via a
low range and high range. When this mode is selected the analyzer will
automatically switch between the two ranges dynamically as the
concentration value fluctuates.
Range status is also output via the external digital I/O status outputs (See Section
To select the Analog Output Range Type press:

When the single range mode is selected (SNGL), all concentration outputs (A1,
A2 and A3) are slaved together and set to the same reporting range limits (e.g. 0-
22.00 %). The span limit of this reporting range can be set to any value within the
physical range of the analyzer.
Although the outputs share the same concentration reporting range, the electronic
signal ranges of the analog outputs may still be configured for different values
(e.g. 0-5 VDC, 0-10 VDC, etc; see Section 5.10.2)

5.4.3.2. RNGE MODE DUAL: CONFIGURING THE T803 ANALYZER FOR DUAL
RANGE MODE
Selecting the DUAL range mode allows the A1 and A2 outputs to be configured
with different reporting ranges. The analyzer software calls these two ranges
RNG1 (low) and RNG2 (high).
The C2L RANGE 1 setting corresponds with the analog output labeled A1 on the rear panel of
the instrument.
The C2H RANGE 2 setting corresponds with the A2 output.
In DUAL range mode the RANGE test function displayed on the front panel will
be replaced by two separate functions:
CO2 RN1: The range setting for the A1 output.
CO2 RN2: The range setting for the A2 output.

RANGE MODE
In AUTO range mode, the analyzer automatically switches the reporting range
between two user-defined ranges (low and high).
The unit will switch from low range to high range when the CO2 concentration
exceeds 98% of the low range span.
The unit will return from high range back to low range once the CO2
concentration falls below 75% of the low range span.
In AUTO Range mode the instrument reports the same data in the same range on
both the A1 and A2 outputs and automatically switches both outputs between
ranges as described above.
Also the RANGE test function displayed on the front panel will be replaced by
two separate functions:
CO2 RNG1: The LOW range setting for all analog outputs.
CO2 RNG2: The HIGH range setting for all analog outputs.
The high/low range status is also reported through the external, digital status bits
(See Section 3.3.1.4).

5.4.4. SETUP RNGE DIL: USING THE OPTIONAL DILUTION RATIO
FEATURE
This feature is an optional software utility that is used to compensate for any
dilution of the sample gas that may occur before it enters the sample inlet.
Typically this occurs in continuous emission monitoring (CEM) applications
where the sampling method used to remove the gas from the stack, dilutes the
sample.
Using the dilution ratio option is a 3-step process:
1. Select the reporting range mode and set the reporting range upper limit (see
Section 5.4.3).
Ensure that the upper span limit entered for the reporting range is the
maximum expected concentration of the non-diluted gas.

2. Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent
and 1 part of sample gas):
3. Calibrate the analyzer.
Make sure that the calibration span gas is either supplied through the
same dilution system as the sample gas or has an appropriately lower
actual concentration.
EXAMPLE: If the reporting range limit is set for 100 % and the dilution ratio of the
sample gas is 20, either:
a span gas with the concentration of 100 % can be used if the span gas
passes through the same dilution steps as the sample gas, or;
a 5 % span gas must be used if the span gas IS NOT routed through the
dilution system.
5.5. SETUP PASS: PASSWORD FEATURE
The menu system provides password protection of the calibration and setup
functions to prevent unauthorized adjustments. When the passwords have been
enabled in the PASS menu item, the system will prompt the user for a password
anytime a password-protected function (e.g., SETUP) is selected. This allows
normal operation of the instrument, but requires the password (101) to access to
the menus under SETUP. When PASSWORD is disabled (SETUP>PASS>OFF),

5.10.3. CALIBRATION OF THE ANALOG OUTPUTS
Analog output calibration should to be carried out on first startup of the analyzer
(performed in the factory as part of the configuration process) or whenever
recalibration is required. The analog outputs can be calibrated automatically,
either as a group or individually, or adjusted manually.
In its default mode, the instrument is configured for automatic calibration of all
channels, which is useful for clearing any analog calibration warnings associated
with channels that will not be used or connected to any input or recording device,
e.g., datalogger.
Manual calibration should be used for the 0.1V range or in cases where the
outputs must be closely matched to the characteristics of the recording device.
Manual calibration requires the AUTOCAL feature to be disabled.

5.10.3.5. MANUAL ADJUSTMENT OF CURRENT LOOP OPTION OUTPUT SPAN AND
OFFSET
A current loop option may be purchased for the A1, A2 and A3 analog outputs of
the analyzer. This option places circuitry in series with the output of the A-to-D
converter on the motherboard that changes the normal DC voltage output to a 0-
The outputs can be ordered scaled to any set of limits within that 0-20 mA
range, however most current loop applications call for either 0-20 mA or 4-20
mA range spans.
All current loop outputs have a + 5% over range. Ranges whose lower limit is
set above 1 mA also have a 5% under range.
To switch an analog output from voltage to current loop, follow the instructions
menu).
Adjustment of the signal zero and span levels of the current loop output is done
by raising or lowering the voltage output of the D-to-A converter circuitry on the
analyzer’s motherboard. This raises or lowers the signal level produced by the
current loop option circuitry.
The software allows this adjustment to be made in 100, 10 or 1 count increments.
Since the exact amount by which the current signal is changed per D-to-A count
varies from output-to-output and instrument–to–instrument, you will need to
measure the change in the signal levels with a separate, current meter placed in
the analog output connector.

6. COMMUNICATIONS SETUP AND OPERATION
The T803 is equipped with an Ethernet port, a USB port and two serial
communication (COM) ports (RS232 and COM2) located on the rear panel (see
Figure 3-2). Both COM ports operate similarly and give the user the ability to
communicate with, issue commands to, and receive data from the analyzer
through an external computer system or terminal.
This section provides pertinent information regarding communication equipment,
describes the instrument’s communications modes, presents configuration
instructions for the communications ports, and provides instructions for their use,
including communications protocol. Data acquisition is presented in Section 7.
By default, both COM ports operate on the RS-232 protocol.
6.1. DATA TERMINAL/COMMUNICATION EQUIPMENT (DTE DCE)
RS-232 was developed for allowing communications between data terminal
equipment (DTE) and data communication equipment (DCE). Basic data
terminals always fall into the DTE category whereas modems are always
considered DCE devices.
Electronically, the difference between the DCE and DTE is the pin assignment of
the Data Receive and Data Transmit functions.
DTE devices receive data on Pin 2 and transmit data on Pin 3.
DCE devices receive data on Pin 3 and transmit data on Pin 2.
A switch located below the serial ports on the rear panel allows the user to switch
between DTE (for use with data terminals) or DCE (for use with modems). Since
computers can be either DTE or DCE, check your computer to determine which
mode to use.
6.2. COMMUNICATION MODES, BAUD RATE AND PORT
TESTING
Use the SETUP>MORE>COMM menu to configure COM1 (labeled RS232 on
instrument rear panel) and/or COM2 (labeled COM2 on instrument rear panel)
for communication modes, baud rate and/or port testing for correct connection. If
using a USB option communication connection, setup requires downloading the
USB driver and configuring per Section 6.4.
6.2.1. COM PORT COMMUNICATION MODES
Each of the analyzer’s serial ports can be configured to operate in a number of
the mode ID numbers and displays this combined number on the front panel
display. For example, if quiet mode (01), computer mode (02) and Multi-Drop-

1
Quiet mode suppresses any feedback from the analyzer (such as warning messages) to
the remote device and is typically used when the port is communicating with a computer
program where such intermittent messages might cause communication problems.
Such feedback is still available but a command must be issued to receive them.
Computer mode inhibits echoing of typed characters and is used when the port is
communicating with a computer operated control program.

6.2.4. MACHINE ID
Each type of Teledyne API’s analyzer is configured with a default ID code. The
default ID code for the T803 analyzers is 803.
The ID number is only important if more than one analyzer is connected to the
same communications channel such as when several analyzers are:
on the same Ethernet LAN (see Section 6.3);
in a RS-232 multidrop chain (see Section 3.3.1.8) or;
operating over a RS-485 network (see Section 3.3.1.8).
If two analyzers of the same model type are used on one channel, the ID codes of
one or both of the instruments needs to be changed.
To edit the instrument’s ID code, press:
The ID can also be used for to identify any one of several analyzers attached to
the same network but situated in different physical locations.

6.3. REMOTE ACCESS VIA THE ETHERNET
For network or Internet communication, the analyzer can be connected to any
standard 10BaseT or 100BaseT Ethernet network via low-cost network hubs,
switches or routers. The interface operates as a standard TCP/IP device on port
3000. This allows a remote computer to connect through the Internet to the
analyzer using APICOM, terminal emulators or other programs.
The Ethernet cable connector on the rear panel has two LEDs indicating the
Ethernet’s current operating status.
Table 6-2: Ethernet Status Indicators
LED
amber (link)
green (activity
FUNCTION
On when connection to the LAN is valid.
Flickers during any activity on the LAN.
The analyzer is shipped with DHCP enabled by default. This allows the
instrument to be connected to a network or router with a DHCP server. The
instrument will automatically be assigned an IP address by the DHCP server. This
configuration is useful for quickly getting an instrument up and running on a
network. However, for permanent Ethernet connections, a static IP address should
address.
6.3.1. CONFIGURING THE ETHERNET USING DHCP
The Ethernet for your T803 uses Dynamic Host Configuration Protocol (DHCP)
to configure its interface with your LAN automatically. This requires that your
network servers also be running DHCP. The analyzer will do this the first time
you turn the instrument on after it has been physically connected to your network.
Note
Check the INET settings the first time you power up your analyzer after it has
been physically connected to the LAN/Internet to make sure that the DHCP
has successfully downloaded the appropriate information from you network
the analyzer’s front panel display.

6.5.2. HESSEN
The Hessen protocol is a multidrop protocol, in which several remote instruments
are connected via a common communications channel to a host computer. The
remote instruments are regarded as slaves of the host computer. The remote
instruments are unaware that they are connected to a multidrop bus and never
initiate Hessen protocol messages. They only respond to commands from the

host computer and only when they receive a command containing their own
unique ID number.
The Hessen protocol is designed to accomplish two things: to obtain the status of
remote instruments, including the concentrations of all the gases measured; and to
place remote instruments into zero or span calibration or measure mode. API’s
implementation supports both of these principal features.
The Hessen protocol is not well defined, therefore while API’s application is
completely compatible with the protocol itself, it may be different from
implementations by other companies.
Note
The following sections describe the basics for setting up your instrument to
operate over a Hessen Protocol network. For more detailed information as
well as a list of host computer commands and examples of command and
response message syntax, download the Manual Addendum for Hessen
Protocol from the Teledyne API web site: http://www.teledyne-
api.com/manuals/.
6.5.2.1. HESSEN COM PORT CONFIGURATION
Hessen protocol requires the communication parameters of the T803’s COM
ports to be set differently than the standard configuration as shown in the table
below.

To change the baud rate of the T803’s COM ports, See Section 6.2.2.
To change the rest of the COM port parameters listed in the table above, see
Note
Make sure that the communication parameters of the host computer are also
properly set.
In addition, rather than issuing commands to the instrument in rapid
succession, bear in mind that the instrument software has a 200 ms latency
period before it responds to commands issued by the host computer.
6.5.2.2. ACTIVATING HESSEN PROTOCOL
Once the COM port has been properly configured, the next step in configuring
the T803 to operate over a Hessen protocol network is to activate the Hessen
mode for COM ports and configure the communication parameters for the port(s)
appropriately.

6.5.2.5. GAS LIST ENTRY FORMAT AND DEFINITIONS
The T803 analyzer keeps a list of available gas types. Each entry in this list is of
the following format.
[GAS TYPE],[RANGE],[GAS ID],[REPORTED]
WHERE:
GAS TYPE = The type of gas being reported (e.g. O2, CO2).
RANGE
=
The concentration range for this entry in the gas list. This feature
permits the user to select which concentration range will be used
for this gas list entry. The T803 analyzer has two ranges:
0 - The HESSEN protocol to use whatever range is currently active.
1 - The HESSEN protocol will always use RANGE1 for this gas list entry
2 - The HESSEN protocol will always use RANGE2 for this gas list entry
3 - Not applicable to the T803 analyzer.
GAS ID
=
=
An identification number assigned to a specific gas. In the case
of the T803 analyzer in its base configuration, there is only one
gas O2 , and its default GAS ID is 110. This ID number should
not be modified.
REPORT
States whether this list entry is to be reported or not reported
when ever this gas type or instrument is polled by the HESSEN
network. If the list entry is not to be reported this field will be
blank.
The T803 analyzer measures CO2 and O2. The default gas list entries are:
O2, 0, 110, REPORTED
CO2, 0, 111, REPORTED
These default settings cause the instrument to report the concentration value of
the currently active range. If you wish to have just concentration value stored for
a specific range, this list entry should be edited or additional entries should be
EXAMPLE: Changing the above O2 gas list entry to read:
CO2, 2, 111, REPORTED
would cause only the last CO2 reading while RANGE2 (HIGH) range was active
to be recorded.

7. DATA ACQUISITION SYSTEM (DAS & APICOM
The T803 analyzer contains a flexible and powerful, internal data acquisition
system (DAS) that enables the analyzer to store concentration and calibration data
as well as a host of diagnostic parameters. The DAS of the T803 can store
several months of data, depending on how it is configured.. The data are stored
in non-volatile memory and are retained even when the instrument is powered
off. Data are stored in plain text format for easy retrieval and use in common
data analysis programs (such as spreadsheet-type programs).
The DAS is designed to be flexible; users have full control over the type, length
and reporting time of the data. The DAS permits users to access stored data
through the instrument’s front panel or its communication ports.
The DAS can be disabled only by disabling or deleting its individual data
channels.
Note
7.1. SETUP DAS: USING THE DATA ACQUISITION
SYSTEM (DAS)
The principal use of the DAS is logging data for trend analysis and predictive
diagnostics, which can assist in identifying possible problems before they affect
the functionality of the analyzer. The secondary use is for data analysis,
documentation and archival in electronic format.
To support the DAS functionality, Teledyne API offers APICOM, a program that
provides a visual interface for remote or local setup, configuration and data
retrieval of the DAS. The APICOM manual (included with the program),
contains a more detailed description of the DAS structure and configuration,
which is briefly described here.
The T803 includes a basic DAS configuration, which is enabled by default. New
data channels are also enabled by default, but each channel may be turned off for
later or occasional use.
IMPORTANT
IMPACT ON READINGS OR DATA
DAS operation is suspended whenever its configuration is edited using
the analyzer’s front panel and therefore data may be lost. To prevent
such data loss, it is recommended to use the APICOM graphical user
interface for DAS changes. Please be aware that all stored data will be
erased if the analyzer’s disk-on-module or CPU board is replaced or if the
configuration data stored there is reset..

The DAS can be disabled, as opposed to suspended, only by disabling or deleting
its individual data channels.
7.1.2. DAS STRUCTURE
The DAS is designed around the feature of a “record”. A record is a single data
point. The type of data recorded in a record is defined by two properties:
PARAMETER type that defines the kind of data to be stored (e.g. the
average of gas concentrations measured with three digits of precision). See
Section 7.1.5.3.
A TRIGGER event that defines when the record is made (e.g. timer; every
The specific PARAMETER and TRIGGER events that describe an individual
Each data channel relates one or more parameters with a specific trigger event
and various other operational characteristics related to the records being made
(e.g., the channel’s name, number of records to be made, time period between
records, whether or not the record is exported via the analyzer’s RS-232 port,
etc.).
The number of DAS objects are limited by the instrument’s finite storage
capacity. For information regarding the maximum number of channels,
parameters, and records and how to calculate the file size for each data channel,
refer to the DAS manual downloadable from the TAPI website at
http://www.teledyne-api.com/manuals/, under Special Manuals.

7.1.2.1. DAS CHANNELS
The key to the flexibility of the DAS is its ability to store a large number of
combinations of triggering events and data parameters in the form of data
channels. Users may create up to 50 data channels and each channel can contain
one or more parameters. For each channel, the following are selected:
One triggering event is selected

CALDAT: Data channels log new slopes and offsets of measurements each time
an O2 zero or span calibration is performed and the result changes the value of the
slope (triggering event: SLPCHG). Although there is a separate data channel for
CO2 (CALCO2), this channel could be configured to include both O2 and CO2.
This data channel will store data from the last 200 calibrations and can
be used to document analyzer calibration; it also is useful for detecting
trends in slope and offset (instrument response) when performing
predictive diagnostics as part of a regular maintenance schedule.
The CALDAT channel collects data based on events (e.g. a calibration
operation) rather than a timed interval and therefore does not represent
any specific length of time. As with all data channels, a date and time
stamp is recorded for every logged data point.
CALCO2: Same as for CALDAT above, but this channel is configured to log
data for CO2.
DETAILED: Samples seven different parameters related to the operating status
of the analyzer’s. For each parameter:
A value is logged once every minute;
An average of the last 60 readings is calculated once every minute.
The last 480 averages are stored (20 days).
This channel is useful for diagnosing problems that cause the instruments
measurements to drift slowly over time
FAST: Almost identical to DETAILED except that for each parameter:
Samples are taken once per minute and reported once per minute, in
effect causing the instrument to record an instantaneous reading of
each parameter every minute.
The last 360 readings for each parameter are recorded/reported.
This channel is useful for diagnosing transients; spikes and noise problems.
These default Data Channels can be used as they are, or they can be customized
from the front panel to fit a specific application. They can also be deleted to
make room for custom user-programmed Data Channels.
Appendix A-5 lists the firmware-specific DAS configuration in plain-text format.
This text file either can be loaded into APICOM and then modified and uploaded
to the instrument, or can be copied and pasted into a terminal program to be sent
to the analyzer.

7.1.5.2. EDITING DAS TRIGGERING EVENTS
Triggering events define when and how the DAS records a measurement of any
given data channel. The most commonly used triggering events are:
ATIMER: Sampling at regular intervals specified by an automatic timer. Most
trending information is usually stored at such regular intervals, which can be
instantaneous or averaged.
EXO2ZR, EXO2SP, EXO2MP, O2SLPC (exit O2 zero, exit O2 span, O2 slope
change); EXCO2Z, EXCO2S, EXCO2M, CO2SLC (exit CO2 zero, exit CO2
span, CO2 slope change); : Sampling at the end of (irregularly occurring)
calibrations or when the response slope changes. These triggering events create

instantaneous data points, e.g., for the new slope and offset (concentration
response) values at the end of a calibration. Zero and slope values are valuable to
monitor response drift and to document when the instrument was calibrated.
WARNINGS: Some data may be useful when stored if one of several warning
messages appears such as CO2TMW, O2TMPW (CO2 or O2sensor temperature
warning). This is helpful for trouble-shooting by monitoring when a particular
warning occurred.
To edit the list of data parameters associated with a specific data channel, follow

Note
DAS Trigger Events are firmware specific; a list of trigger events can

Data parameters are types of data that may be measured and stored by the DAS.
For each Teledyne API analyzer model, the list of available data parameters is
different, fully defined and not customizable. Appendix A-5 lists firmware
specific data parameters for the T803. DAS parameters include things like CO2

concentration measurements, temperatures of the various heaters placed around
the analyzer, pressures and flows of the pneumatic subsystem and other
diagnostic measurements as well as calibration data such as stability, slope and
offset.
Most data parameters have associated measurement units, such as mV, ppb,
cm³/min, etc., although some parameters have no units (e.g. SLOPE). With the
exception of concentration readings, none of these units of measure can be
changed.
Note
DAS does not keep track of the units (i.e. %) of each concentration value;
therefore, DAS data files may contain concentrations data recorded in more
than one type of unit if the units of measure was changed during data
acquisition.
Each data parameter has user-configurable functions that define how the data are
recorded:
Table 7-3: DAS Data Parameter Functions
FUNCTION
EFFECT
PARAMETER
Instrument-specific parameter name.
SAMPLE MODE
INST: Records instantaneous reading.
AVG: Records average reading during reporting interval.
SDEV: Records the standard deviation of the data points recorded during the reporting interval.
MIN: Records minimum (instantaneous) reading during reporting interval.
MAX: Records maximum (instantaneous) reading during reporting interval.
PRECISION
0 to 4: Sets the number of digits to the right decimal point for each record.
Example: Setting 4; “399.9865 %”
Setting 0; “400 %”
STORE NUM.
SAMPLES
OFF: Stores only the average (default).
ON: Stores the average and the number of samples used to compute the value of the
parameter. This property is only useful when the AVG sample mode is used. Note that the
number of samples is the same for all parameters in one channel and needs to be specified only
for one of the parameters in that channel.
Users can build a channel by selecting desired parameters from the available
choices.
Data channels can be edited individually from the front panel without affecting
other data channels. However, when editing a data channel, such as during
adding, deleting or changing parameters, all data for that particular channel will
be lost, because the DAS can store only data of one format (number of parameter
columns etc.) for any given channel. In addition, a DAS configuration can only
be uploaded remotely as an entire set of channels. Hence, remote update of the
DAS will always delete all current channels and stored data.

When the STORE NUM SAMPLES feature is turned on, the instrument
will store the number of measurements that were used to compute the
AVG, SDEV, MIN or MAX value but not the actual measurements
themselves.
7.1.5.4. EDITING SAMPLE PERIOD AND REPORT PERIOD
The DAS defines two principal time periods by which sample readings are taken
and permanently recorded:
SAMPLE PERIOD: Determines how often DAS temporarily records a sample
reading of the parameter in volatile memory. SAMPLE PERIOD is only used
when the DAS parameter’s sample mode is set for AVG, SDEV, MIN or MAX
The SAMPLE PERIOD is set to one minute by default and generally cannot be
accessed from the standard DAS front panel menu, but is available via the
instrument’s communication ports by using APICOM or the analyzer’s standard
serial data protocol.
REPORT PERIOD: Sets how often the sample readings stored in volatile
memory are processed, (e.g. average, minimum or maximum are calculated); the
results stored permanently in the instrument’s Disk-on-Module as well as
transmitted via the analyzer’s communication ports. The Report Period may be
set from the front panel. If the INST sample mode is selected, the instrument
stores and reports an instantaneous reading of the selected parameter at the end of
the chosen report period.

then press:
The SAMPLE PERIOD and REPORT PERIOD intervals are synchronized to
the beginning and end of the appropriate interval of the instrument’s internal
clock.
If SAMPLE Period were set for one minute, the first reading would occur at the
beginning of the next full minute according to the instrument’s internal clock.
If the Report period were set for one hour, the first report activity would occur at
the beginning of the next full hour according to the instrument’s internal clock.
EXAMPLE:
Given the above settings, if DAS were activated at 7:57:35 the first sample would
occur at 7:58 and the first report would be calculated at 8:00 consisting of data
points for 7:58, 7:59 and 8:00. During the next hour (from 8:01 to 9:00), the
instrument will take a sample reading every minute and include 60 sample
readings.

7.1.5.5. REPORT PERIODS IN PROGRESS WHEN INSTRUMENT IS POWERED OFF
If the instrument is powered off in the middle of a REPORT PERIOD, the
samples accumulated so far during that period are lost. Once the instrument is
turned back on, the DAS begins taking samples and temporarily storing them in
volatile memory as part of a new REPORT PERIOD. At the end of this
REPORT PERIOD, only the sample readings taken since the instrument was
turned back on will be included in any AVG, SDEV, MIN or MAX calculation.
Also, the STORE NUM SAMPLE feature will report the number of sample
readings taken since the instrument was restarted.
7.1.5.6. EDITING THE NUMBER OF RECORDS
The number of data records in the DAS is cumulative across all channels and
parameters, filling about one megabyte of space on the disk-on-module; this
means that the actual number of records is limited by the total number of
parameters and channels and other settings in the DAS configuration. Every
additional data channel (up to 20), parameter (up to 50 per channel), number of
samples setting etc. will govern the maximum amount of data points.
The DAS will check the amount of available data space and prevent the user from
specifying too many records at any given point. If, for example, the DAS
memory space can accommodate 375 more data records, the ENTR button will
disappear when trying to specify more than that number of records. This check
for memory space may also make an upload of a DAS configuration with
APICOM or a terminal program fail, if the combined number of records would be
exceeded. In this case, it is suggested to either try to determine what the
maximum number of records available is using the front panel interface or use
trial-and-error in designing the DAS script or calculate the number of records
using the DAS or APICOM manuals.

7.1.5.9. THE COMPACT REPORT FEATURE
When enabled, this option avoids unnecessary line breaks on all RS-232 reports.
Instead of reporting each parameter in one channel on a separate line, up to five
parameters are reported in one line.
The COMPACT DATA REPORT generally cannot be accessed from the
standard DAS front panel menu, but is available via the instrument’s
communication ports by using APICOM or the analyzer’s standard serial data
protocol.
7.1.5.10. THE STARTING DATE FEATURE
This option allows specifying a starting date for any given channel when the user
wants to start data acquisition only after a certain time and date. If the
STARTING DATE is in the past (the default condition), the DAS ignores this
setting and begins recording data as defined by the REPORT PERIOD setting.
The STARTING DATE generally cannot be accessed from the standard DAS
front panel menu, but is available via the instrument’s communication ports by
using APICOM or the analyzer’s standard serial data protocol.

8. REMOTE OPERATION
This section provides information needed when using external digital and serial
I/O for remote operation. It assumes that the electrical connections have been
made as described in Section 3.3.1.
Your analyzer can be remotely configured, calibrated or queried for stored data
through the serial ports, via either Computer mode (using a personal computer)
or Interactive mode (using a terminal emulation program).
8.1. COMPUTER MODE
Computer Mode is used when the analyzer is connected to a computer with a
dedicated interface program such as APICOM.
8.1.1. REMOTE CONTROL VIA APICOM
APICOM is an easy-to-use, yet powerful interface program that allows the user to
access and control any of Teledyne API’s main line of ambient and stack-gas
instruments from a remote connection through direct cable, modem or Ethernet.
Running APICOM, a user can:
Establish a link from a remote location to the T803 through direct cable
connection via RS-232 modem or Ethernet.
View the instrument’s front panel and remotely access all functions that could
be accessed when standing in front of the instrument.
Remotely edit system parameters and set points.
Download, view, graph and save data for predictive diagnostics or data
analysis.
Check on system parameters for trouble-shooting and quality control.
APICOM is very helpful for initial setup, data analysis, maintenance, and
which emulates the look and functionality of the instruments actual front panel.
APICOM is included free of cost with the analyzer and the latest versions can
also be downloaded at http://www.teledyne-api.com/software/.

8.2.1.3. DATA TYPES
Data types consist of integers, hexadecimal integers, floating-point numbers,
Boolean expressions and text strings.
Integer data: Used to indicate integral quantities such as a number of records, a
filter length, etc.
They consist of an optional plus or minus sign, followed by one or more
digits.
For example, +1, -12, 123 are all valid integers.
Hexadecimal integer data: Used for the same purposes as integers.
They consist of the two characters “0x,” followed by one or more hexadecimal
digits
(0-9, A-F, a-f), which is the ‘C’ programming language convention.
No plus or minus sign is permitted.
For example, 0x1, 0x12, 0x1234abcd are all valid hexadecimal integers.
Floating-point number: Used to specify continuously variable values such as
temperature set points, time intervals, warning limits, voltages, etc.
They consist of an optional plus or minus sign, followed by zero or more
digits, an optional decimal point and zero or more digits.
At least one digit must appear before or after the decimal point.
Scientific notation is not permitted.
For example, +1.0, 1234.5678, -0.1, 1 are all valid floating-point numbers.
Boolean expressions: Used to specify the value of variables or I/O signals that
may assume only two values.
They are denoted by the keywords ON and OFF.

Remote Operation
Teledyne API T803 CO2/O2 Analyzer Operation Manual
Text strings: Used to represent data that cannot be easily represented by other
data types, such as data channel names, which may contain letters and numbers.
They consist of a quotation mark, followed by one or more printable
characters, including spaces, letters, numbers, and symbols, and a final
quotation mark.
For example, “a”, “1”, “123abc”, and “()[]<>” are all valid text strings.
It is not possible to include a quotation mark character within a text string.
Some commands allow you to access variables, messages, and other items. When
using these commands, you must type the entire name of the item; you cannot
abbreviate any names.
8.2.1.4. STATUS REPORTING
Reporting of status messages as an audit trail is one of the three principal uses for
the RS-232 interface (the other two being the command line interface for
controlling the instrument and the download of data in electronic format). You
can effectively disable the reporting feature by setting the interface to quiet mode
Status reports include warning messages, calibration and diagnostic status
messages. Refer to Appendix A-3 for a list of the possible messages.
8.2.1.5. GENERAL MESSAGE FORMAT
All messages from the instrument (including those in response to a command line
request) are in the format:
X DDD:HH:MM [Id] MESSAGE<CRLF>
Where:
X
is a command type designator, a single character indicating the
message type, as shown in the Table 8-2.
DDD:HH:MM is the time stamp, the date and time when the message was
issued. It consists of the Day-of-year (DDD) as a number from 1
to 366, the hour of the day (HH) as a number from 00 to 23, and
the minute (MM) as a number from 00 to 59.
[ID]
is the analyzer ID, a number with 1 to 4 digits.
MESSAGE
is the message content that may contain warning messages, test
measurements, variable values, etc.
<CRLF>
is a carriage return line feed pair, which terminates the message.
The uniform nature of the output messages makes it easy for a host computer to
parse them into an easy structure. Keep in mind that the front panel display does
not give any information on the time a message was issued, hence it is useful to
log such messages for trouble-shooting and reference purposes. Terminal
emulation programs such as HyperTerminal can capture these messages to text
files for later review.

8.2.1.6. COM PORT PASSWORD SECURITY
In order to provide security for remote access of the T803, a LOGON feature can
be enabled to require a password before the instrument will accept commands.
Once the SECURITY MODE is enabled, the following items apply.
A password is required before the port will respond or pass on commands.
If the port is inactive for one hour, it will automatically logoff, which can also
be achieved with the LOGOFF command.
Three unsuccessful attempts to log on with an incorrect password will cause
subsequent logins to be disabled for 1 hour, even if the correct password is
used.
If not logged on, the only active command is the '?' request for the help
screen.
The following messages will be returned at logon:
LOGON SUCCESSFUL - Correct password given
LOGON FAILED - Password not given or incorrect
LOGOFF SUCCESSFUL - Connection terminated successfully
To log on to the T803 analyzer with SECURITY MODE feature enabled, type:
LOGON 940331
Note
To change the default password, use the variable RS-232_PASS issued as
follows:
V RS-232_PASS=NNNNNN
Where N is any numeral between 0 and 9.
8.3. REMOTE ACCESS BY MODEM
The T803 can be connected to a modem for remote access. This requires a cable
between the analyzer’s COM port and the modem, typically a DB-9F to DB-25M
cable (available from Teledyne API with PN WR0000024).
Once the cable has been connected, check to make sure:

9. CALIBRATION PROCEDURES
This section contains a variety of information regarding the various methods for
calibrating a T803 as well as other supporting information
This section is organized as follows:
Section 9.1 – Before Calibration
This section contains general information you should know before calibrating the
analyzer.
This section describes the procedure for checking the calibration of the T803 and
calibrating the instrument. Also included are instructions for selecting the
reporting range to be calibrated when the T803 analyzer is set to operate in either
the DUAL or AUTO reporting range modes.
This section describes how to judge the effectiveness of a recently performed
calibration.
This section describes how to perform calibrations of the T803’s electronic
systems, including:
adjusting the analyzers internal flow sensor
adjusting the analyzers internal pressure sensor
Note
Throughout this Section are various diagrams showing pneumatic
connections between this instrument and various other pieces of equipment
such as calibrators and zero air sources. These diagrams are only intended
to be schematic representations of these connections and do not reflect
actual physical locations of equipment and fitting location or orientation.

Calibration Procedures
Teledyne API T803 CO2/O2 Analyzer Operation Manual
9.1. BEFORE CALIBRATION
The calibration procedures in this section assume that the range mode, analog
range and units of measure have already been selected for the analyzer. If this
has not been done, please do so before continuing (see Section 5.2 for
instructions).
Note
If any problems occur while performing the following calibration
procedures, refer to Section 11 for troubleshooting tips.
9.1.1. REQUIRED EQUIPMENT, SUPPLIES, AND EXPENDABLES
Calibration of the T803 analyzer requires a certain amount of equipment and
supplies. These include, but are not limited to, the following:
Zero-air source.
Span gas source.
Gas lines - All Gas lines should be Stainless Steel, PTFE (Teflon), glass or
electroless nickel.
A recording device such as a strip-chart recorder and/or data logger (optional).
For electronic documentation, the internal data acquisition system can be
used.
9.1.2. CALIBRATION GASES
9.1.2.1. ZERO AIR
A gas that is similar in chemical composition to the earth’s atmosphere but
scrubbed of all components that might affect the analyzer’s readings. Teledyne
API recommends using pure N2 when calibrating the zero point of your CO2 or
O2 sensor except if known interferents are involved (please refer to Section
CAUTION
GENERAL SAFETY HAZARD
DO NOT vent calibration gases into enclosed areas. Rapid release of pure N2 gas into
an enclosed space can displace oxygen, and therefore represents an asphyxiation
hazard. This may happen with few warning symptoms.
9.1.2.2. SPAN GAS
A gas specifically mixed to match the chemical composition of the type of gas
being measured at near full scale of the desired measurement range. In this case,
O2 measurements made with the T803 analyzer, Teledyne API recommends using
21% O2 in N2 when calibrating the span point of the O2 sensor and 16% CO2 in
N2 when calibrating the span point of the CO2 sensor..

Note
For span point calibration it is generally a good idea to use 80% of the reporting
range for that channel. For instance, if the reporting range of the instrument is
set for 5%, the proper span gas would be 4%.
9.1.3. DATA RECORDING DEVICES
A strip chart recorder, data acquisition system or digital data acquisition system
should be used to record data from the serial or analog outputs of the T803.
If analog readings are used, the response of the recording system should be
checked against a NIST traceable voltage source or meter.
Data recording devices should be capable of bi-polar operation so that
negative readings can be recorded.
For electronic data recording, the T803 provides an internal data acquisition
system (DAS), which is described in detail in Section 7.1
APICOM, a remote control program, is also provided as a convenient and
powerful tool for data handling, download, storage, quick check and plotting (see

9.2.3.1. SETTING THE EXPECTED SPAN GAS CONCENTRATION
NOTE
When setting expected concentration values, consider impurities in your span gas.
The expected CO2 span gas concentration should be 80% of the reporting range
of the instrument (see Section 5.4.1)
The default factory setting is 16% for CO2 or 20.95 % for O2. To set the span
gas concentration, press:

9.3. ASSESSING CALIBRATION QUALITY
After completing one of the calibration procedures described above, it is
important to evaluate the analyzer’s calibration SLOPE and OFFSET
parameters. These values describe the linear response curve of the analyzer. The
values for these terms, both individually and relative to each other, indicate the
quality of the calibration.
To perform this quality evaluation, you will need to record the values of both test
in the DAS channel CALDAT for data analysis, documentation and archival.
Make sure that these parameters are within the limits listed below and frequently
compare them to those values on the Final Test and Checkout Sheet (PN
068360000) that came attached to your manual, which should not be significantly

These values should not be significantly different from the values recorded on the Teledyne API
Final Test and Validation Data Sheet that was shipped with your instrument.
The default DAS configuration records all calibration values in channel
CALDAT as well as all calibration check (zero and span) values in its internal
memory.
Up to 200 data points are stored for up 4 years of data (on weekly calibration
checks) and a lifetime history of monthly calibrations.
Review these data to see if the zero and span responses change over time.
These channels also store the STABIL values (standard deviation of the CO2
and the O2 concentrations) to evaluate if the analyzer response has properly
leveled off during the calibration procedure.

SUBSYSTEMS
9.4.1. PRESSURE CALIBRATION
A sensor in the sample path continuously measures the pressure of the sample
gas. This data is used to compensate the measured CO2 and O2 concentrations for
changes in atmospheric pressure and is stored in the CPU’s memory as the test
function PRES (also viewable via the front panel).
To carry out this adjustment, the current ambient atmospheric pressure must be
known.
Before performing the following pressure calibration, ensure that the pressure
being measured by the analyzer’s internal sensor is equal to ambient atmospheric
pressure by disconnecting:
The sample gas pump and;
The sample gas-line vent from the sample gas inlet on the instrument’s rear
panel.

The flow calibration allows the user to adjust the values of the sample flow rates
as they are displayed on the front panel and reported through COM ports to match
the actual flow rate measured at the SAMPLE inlet. This does not change the
hardware measurement of the flow sensors, only the software-calculated values.
To carry out this adjustment, connect an external, sufficiently accurate flow meter
to the sample inlet. Once the flow meter is attached and is measuring actual gas

10.2. PREDICTIVE DIAGNOSTICS
The Test Functions can be used to predict failures by looking at how their values
change over time. Initially it may be useful to compare the state of these Test
Functions to the values recorded on the printed record of the final calibration
for taking action as these values change with time. The internal data acquisition
system (DAS) is a convenient way to record and track these changes. Use
APICOM to download and review this data from a remote location.

Maintenance Schedule & Procedures
Teledyne API T803 CO2/O2 Analyzer Operation Manual
To change the filter:
1. Turn OFF the analyzer to prevent drawing debris into the instrument.
2. Open the T803’s hinged front panel and unscrew the knurled retaining ring on
the filter assembly.
Figure 10-1:
Sample Particulate Filter Assembly
3. Carefully remove the retaining ring, PTFE o-ring, glass filter cover and filter
element.
4. Replace the filter, being careful that the element is fully seated and centered
in the bottom of the holder.
5. Re-install the PTFE o-ring (with the notches up), the glass cover, then screw
on the retaining ring and hand tighten. Inspect the seal between the edge of
filter and the o-ring to assure a proper seal.
6. Re-start the analyzer.
10.3.2. REBUILDING THE SAMPLE PUMP
The diaphragm in the sample pump periodically wears out and must be replaced.
A sample rebuild kit is available – see Appendix B of this manual for the part
number of the pump rebuild kit. Instructions and diagrams are included with the
kit.
Always perform a Flow and Leak Check after rebuilding the Sample Pump.

OXYGEN IS A STRONG OXIDIZER.
ONLY Perform Leak Checks using N2 gas and after thoroughly purging the analyzer’s
internal pneumatics.
Leaks are the most common cause of analyzer malfunction; Section 10.3.3.1
procedure.
10.3.3.1. VACUUM LEAK CHECK AND PUMP CHECK
This method is easy and fast. It detects, but does not locate most leaks. It also
verifies that the sample pump is in good condition.
1. Turn the analyzer ON, and allow enough time for flows to stabilize.
2. Cap the SAMPLE inlet port.
3. After several minutes, when the pressures have stabilized, note the following.
In the TEST menu, note the SAMPLE PRESSURE reading.
4. If the reading is < 10 in-Hg, the pump is in good condition and there are no
large leaks.
5. Check the sample gas flow. If the flow is <10 cm3/min and stable, there are
no large leaks in the instrument’s pneumatics.
10.3.3.2. PRESSURE LEAK CHECK
If you can’t locate the leak by the above procedure, use the following procedure.
Obtain a leak checker similar to the Teledyne API PN 01960, which contains a
small pump, shut-off valve and pressure gauge. Alternatively, a convenient
source of low-pressure gas is a tank of span gas, with the two-stage regulator
adjusted to less than 15 psi with a shutoff valve and pressure gauge.

Maintenance Schedule & Procedures
Teledyne API T803 CO2/O2 Analyzer Operation Manual
CAUTION
GENERAL SAFETY HAZARD
Do not use bubble solution with vacuum applied to the analyzer. The solution may
contaminate the instrument. Do not exceed 15 PSI pressure.
1. Turn OFF power to the instrument.
2. Install a leak checker or tank of gas as described above on the SAMPLE inlet
at the rear panel.
3. Remove the instrument cover and locate the inlet side of the sample pump.
Remove the flow assembly from the pump and plug it with the appropriate
gas-tight fitting.
4. Pressurize the instrument with the leak checker, allowing enough time to fully
pressurize the instrument through the critical flow orifice. Do not exceed 15
psi pressure. Check each fitting with soap bubble solution, looking for
bubbles. Once the fittings have been wetted with soap solution, do not re-
apply vacuum, as it will suck soap solution into the instrument and
contaminate it. Wipe down and thoroughly dry all parts first.
5. Once the leak has been located and repaired, the leak-down rate should be
< 1 in-Hg (0.4 psi) in 5 minutes after the pressure is shut off.
10.3.4. PERFORMING A SAMPLE FLOW CHECK
CAUTION
GENERAL SAFETY HAZARD
Always use a separate calibrated flow meter capable of measuring flows in the 0 – 1000
cm3/min range to measure the gas flow rate though the analyzer.
DO NOT use the built in flow measurement viewable from the Front Panel of the instrument.
This measurement is only for detecting major flow interruptions such as clogged or plugged
gas lines.
3-4). Ensure that the inlet to the Flow Meter is at atmospheric pressure.
2. Sample flow should be 120 cm3/min 10%.
3. Once an accurate measurement has been recorded by the method described
above, adjust the analyzer’s internal flow sensors (See Section 9.4.2).
Low flows indicate blockage somewhere in the pneumatic pathway, typically a
plugged sintered filter or critical flow orifice in one of the analyzer’s flow control
assemblies. High flows indicate leaks downstream of the Flow Control
Assembly.
10.3.5. CLEANING EXTERIOR SURFACES OF THE T803
If necessary, the exterior surfaces of the T803 can be cleaned with a clean damp
cloth. Do NOT submerge any part of the instrument and do NOT use any
cleaning solution.

11. TROUBLESHOOTING AND SERVICE
This section describes a variety of methods for identifying the source of
performance problems with the analyzer. Also included here are procedures that
are used to repair the instrument.
HAZARD
STRONG OXIDIZER
OXYGEN IS A STRONG OXIDIZER.
Before working with the casing open, be sure to turn off power supply, and perform
air or N2 gas purging of not only the analyzer inside, but also the sample gas line.
In addition, carefully prevent oil and grease from adhering to any piping. Otherwise,
poisoning, fire or explosion may be caused due to gas leakage, etc.
NOTE
QUALIFIED PERSONNEL
The operations outlined in this Section must be performed by qualified maintenance
personnel only.
CAUTION
RISK OF ELECTRICAL SHOCK
Some operations need to be carried out with the instrument open and running.
Exercise caution to avoid electrical shocks and electrostatic or mechanical damage to
the analyzer.
Do not drop tools into the analyzer or leave them after your procedures.
Do not shorten or touch electric connections with metallic tools while operating
inside the analyzer.
Use common sense when operating inside a running analyzer.
11.1. GENERAL TROUBLESHOOTING
The T803 CO2/O2 analyzer has been designed so that problems can be rapidly
detected, evaluated and repaired. During operation, it continuously performs
diagnostic tests and provides the ability to evaluate its key operating parameters
without disturbing monitoring operations.
A systematic approach to troubleshooting will generally consist of the following
five steps:

Troubleshooting and Service
Teledyne API T803 CO2/O2 Analyzer Operation Manual
1. Note any WARNING MESSAGES and take corrective action as necessary.
2. Examine the values of all TEST functions and compare them to factory
values. Note any major deviations from the factory values and take
corrective action.
3. Use the internal electronic status LEDs to determine whether the electronic
communication channels are operating properly.
Verify that the DC power supplies are operating properly by checking the
voltage test points on the relay PCA.
Note that the analyzer’s DC power wiring is color-coded and these colors
match the color of the corresponding test points on the relay PCA.
4. SUSPECT A LEAK FIRST!
Technical Support data indicate that the majority of all problems are
eventually traced to leaks in the internal pneumatics of the analyzer or the
diluent gas and source gases delivery systems.
Check for gas flow problems such as clogged or blocked internal/external gas
lines, damaged seals, punctured gas lines, a damaged / malfunctioning
pumps, etc.

See the wiring interconnect diagram and interconnect list in Appendix D.
11.1.1. FAULT DIAGNOSIS WITH WARNING MESSAGES
The most common and/or serious instrument failures will result in a warning
along with their meaning and recommended corrective action.
It should be noted that if more than two or three warning messages occur at the
same time, it is often an indication that some fundamental analyzer sub-system
(power supply, relay board, motherboard) has failed rather than indication of the
of the specific failures referenced by the warnings. In this case, it is
confirmed before addressing the specific warning messages.
The analyzer will alert the user that a Warning Message is active by flashing the
FAULT LED, displaying the Warning message in the Param field along with the
CLR button (press to clear Warning message). The MSG button displays if there
is more than one warning in queue or if you are in the TEST menu and have not
yet cleared the message. The following display/touchscreen examples provide an
illustration of each:

11.1.2. FAULT DIAGNOSIS WITH TEST FUNCTIONS
In addition to being useful as predictive diagnostic tools, the test functions
viewable from the front panel can be used to isolate and identify many
operational problems when combined with a thorough understanding of the
analyzer’s theory of operation (Section 12).
The acceptable ranges for these test functions are listed in the “Nominal Range”
column of the analyzer Final Test and Validation Data Sheet (PN 068360000)
shipped with the instrument. Values outside these acceptable ranges indicate a
failure of one or more of the analyzer’s subsystems. Functions whose values are
still within the acceptable range but have significantly changed from the
measurement recorded on the factory data sheet may also indicate a failure.
Note
A worksheet has been provided in Appendix C to assist in recording the
value of these test functions. This worksheet also includes expected values
for the various test functions.
The following table contains some of the more common causes for these values to
be out of range.

11.1.3. DIAG SIGNAL I/O: USING THE DIAGNOSTIC SIGNAL I/O
FUNCTION
The signal I/O diagnostic mode allows access to the digital and analog I/O in the
analyzer. Some of the digital signals can be controlled through the touchscreen.
These signals, combined with a thorough understanding of the instruments
ways:
The technician can view the raw, unprocessed signal level of the analyzer’s
critical inputs and outputs.
Many of the components and functions that are normally under algorithmic
control of the CPU can be manually exercised.
The technician can directly control the signal level Analog and Digital Output
signals.
This allows the technician to observe systematically the effect of directly
controlling these signals on the operation of the analyzer. The following
flowchart shows an example of how to use the Signal I/O menu to view the raw
voltage of an input signal or to control the state of an output voltage or control
signal.

11.2. USING THE INTERNAL ELECTRONIC STATUS LEDS
Several LEDs are located inside the instrument to assist in determining if the
analyzer’s CPU, I2C bus and relay board are functioning properly.
11.2.1. CPU STATUS INDICATOR
DS5, a red LED, that is located on upper portion of the motherboard, just to the
right of the CPU board, flashes when the CPU is running the main program loop.
After power-up, approximately 30 to 60 seconds, DS5 should flash on and off. If
characters are written to the front panel display but DS5 does not flash, then the
program files have become corrupted. If after 30 – 60 seconds neither the DS5 is
flashing or no characters have been written to the front panel display, then the
CPU is bad and must be replaced.

11.3. GAS FLOW PROBLEMS
When troubleshooting flow problems, it is a good idea to first confirm that the
actual flow and not the analyzer’s flow sensor and software are in error, or the
flow meter is in error. Use an independent flow meter to perform a flow check as
pressure sensors as described in Section 11.6.8.
In general, flow problems can be divided into three categories:
Flow is too high
Flow is greater than zero, but is too low, and/or unstable
Flow is zero (no flow)
When troubleshooting flow problems, it is crucial to confirm the actual flow rate
without relying on the analyzer’s flow display. The use of an independent,
external flow meter to perform a flow check as described in Section 10.3.4 is
essential.
The flow diagrams found in a variety of locations within this manual depicting
the T803 in its standard configuration and with options installed, can help in
trouble-shooting flow problems. For your convenience the diagrams are collected
here.

11.3.2. TYPICAL SAMPLE GAS FLOW PROBLEMS
11.3.2.1. FLOW IS ZERO
The unit displays a SAMPLE FLOW warning message on the front panel display
or the SAMPLE FLOW test function reports a zero or very low flow rate.
Confirm that the sample pump is operating (turning). If not, use an AC voltmeter
to make sure that power is being supplied to the pump. If no power is present at
the electrical leads of the pump, take the following steps:.
1. If AC power is being supplied to the pump, but it is not turning, replace the
pump.
2. If the pump is operating but the unit reports no gas flow, perform a flow check
as described in Section 10.3.4.
3. If no independent flow meter is available:
Disconnect the gas lines from both the sample inlet and the exhaust
outlet on the rear panel of the instrument.
Make sure that the unit is in basic SAMPLE Mode.
Place a finger over a Sample inlet on the rear panel of the instrument.
If gas is flowing through the analyzer, you will feel a vacuum suction at
the inlet.
4. If gas flows through the instrument when it is disconnected from its sources
of zero air, span gas or sample gas, the flow problem is most likely not
internal to the analyzer. Check to ensure that:
All calibrators/generators are turned on and working correctly.
Gas bottles are not empty or low.
Valves, regulators and gas lines are not clogged or dirty.
11.3.2.2. LOW FLOW
1. Check if the pump diaphragm is in good condition. If not, rebuild the pump

and re-check.
3. Check for the sample filter and the orifice filter for dirt. Replace filters (See
4. Check for partially plugged pneumatic lines. Clean or replace them.
5. Check for plugged or dirty critical flow orifices. Replace them.
11.3.2.3. HIGH FLOW
The most common cause of high flow is a leak in the sample flow control. If no
leaks or loose connections are found in the fittings or the gas line between the
orifice and the pump, replace the critical flow orifice inside the sample flow
control assembly.

11.3.2.4. DISPLAYED FLOW WARNINGS
This warning means that there is inadequate gas flow. There are four conditions
that might cause this:
A leak upstream or downstream of the flow sensor
A flow obstruction upstream or downstream of the flow sensor
Bad Flow Sensor Board
Bad pump
To determine which condition is causing the flow problem, view the sample
pressure and sample flow functions on the front panel display. If the sample
pressure is reading abnormally low, then the cause is likely a flow obstruction
upstream of the flow sensor. First, check the sample filter and make sure it is not
plugged and then systematically check all the other components upstream of the
orifice to ensure that they are not obstructed.
If the sample pressure is reading normal but the sample flow is reading low, then
it is likely that the pump diaphragm is worn or there is an obstruction downstream
of the flow sensor.
11.3.2.5. ACTUAL FLOW DOES NOT MATCH DISPLAYED FLOW
If the actual flow measured does not match the displayed flow, but is within the
limits of 110-130 cm3/min, adjust the calibration of the flow measurement as
described in Section 10.3.4.
11.3.2.6. SAMPLE PUMP
The sample pump should start immediately after the front panel power switch is
turned ON. With the SAMPLE inlet plugged the test function PRES should read
less than 10”-Hg for a pump in good condition. Readings above 10” Hg indicate
that the pump needs rebuilding. If the test function SAMP FL is greater than 10
cm3/min there is a leak in the pneumatic lines.
11.4. CALIBRATION PROBLEMS
11.4.1. MISCALIBRATED
There are several symptoms that can be caused by the analyzer being
miscalibrated. Miscalibration is indicated by out-of-range Slopes and Offsets as
displayed through the test functions and is frequently caused by the following:
Bad span gas: This can cause a large error in the slope and a small error in
the offset. Delivered from the factory, the T803’s slope is within ±15% of
nominal. Bad span gas will cause the analyzer to be calibrated to the wrong
value. If in doubt have the span gas checked by and independent lab.
Contaminated zero gas: Excess H2O can cause a positive or negative offset
and will indirectly affect the slope.
Dilution calibrator not set up correctly or is malfunctioning: This will also
cause the slope, but not the zero, to be incorrect. Again the analyzer is being
calibrated to the wrong value.
Too many analyzers on the manifold: This can cause either a slope or offset
error because ambient gas with its pollutants will dilute the zero or span gas.

11.4.2. NON-REPEATABLE ZERO AND SPAN
As stated earlier, leaks both in the T803 and in the external system are a
common source of unstable and non-repeatable readings.
Don’t forget to consider pneumatic components in the gas delivery system
outside the T803 Such as:
A change in zero air source such as ambient air leaking into zero air line,
or;
A change in the span gas concentration due to zero air or ambient air
leaking into the span gas line.
2. Once the instrument passes a leak check, do a flow check (See Section
10.3.4) to make sure adequate sample is being delivered to the sensor
assembly.
3. Confirm the sample pressure, sensor temperatures, and sample flow
readings are correct and have steady readings.
4. Disconnect the exhaust line from the optical bench near the rear of the
instrument and plug this line into the SAMPLE inlet creating a pneumatic
loop. The concentration (either zero or span) now must be constant. If
readings become quiet, the problem is in the external pneumatics supplies for
sample gas, span gas or zero air.
11.4.3. INABILITY TO SPAN – NO SPAN BUTTON
1. Confirm that the oxygen span gas source is accurate; this can be done by
opening the analyzer’s SAMPLE inlet to ambient air. If the concentration is
not displayed as ~20.9%, there is a problem with the span gas.
3. Make sure that the expected span gas concentration entered into the
instrument during calibration, is the correct span gas concentration and not
too different from expected span value. This can be viewed via the CONC
submenu of the Sample displays.
4. Check to make sure that there is no ambient air or zero air leaking into span
gas line.
11.4.4. INABILITY TO ZERO – NO ZERO BUTTON
1. Confirm that there is a good source of zero air. Dilute a tank of span gas with
the same amount of zero air from two different sources. If the O2
concentration of the two measurements is different, there is a problem with
one of the sources of zero air.
3. Check to make sure that there is no ambient air leaking into zero air line.
11.5. OTHER PERFORMANCE PROBLEMS
Dynamic problems (i.e. problems which only manifest themselves when the
analyzer is monitoring sample gas) can be the most difficult and time consuming
to isolate and resolve. The following provides an itemized list of the most
common dynamic problems with recommended troubleshooting checks and
corrective actions.

11.5.1. TEMPERATURE PROBLEMS
Individual control loops are used to maintain the set point of the temperatures to
both sensors.. If any of these temperatures are out of range or are poorly
controlled, the T803 will perform poorly.
BOX TEMPERATURE
The box temperature sensor is mounted to the motherboard and cannot be
disconnected to check its resistance. Rather check the BOX TEMP signal using
parameter will vary with ambient temperature, but at ~30oC (6-7° above room
temperature) the signal should be ~1450 mV.
11.6. SUBSYSTEM CHECKOUT
failures or performance problems within the analyzer. In most cases this included
a list of possible causes. This describes how to determine individually determine
if a certain component or subsystem is actually the cause of the problem being
investigated.
11.6.1. AC MAINS CONFIGURATION
The analyzer is correctly configured for the AC mains voltage in use if:
1. The Sample Pump is running.
2. If incorrect power is suspected, check that the correct voltage and frequency
is present at the line input on the rear panel.
If the unit is set for 230 VAC and is plugged into 115VAC, or 100VAC the
sample pump will not start, and the heaters will not come up to
temperature.
If the unit is set for 115 or 100 VAC and is plugged into a 230 VAC circuit,
the circuit breaker built into the ON/OFF Switch on the Front Panel will
trip to the OFF position immediately after power is switched on.
11.6.2. DC POWER SUPPLY
If you have determined that the analyzer’s AC mains power is working, but the
unit is still not operating properly, there may be a problem with one of the
instrument’s switching power supplies. The supplies can have two faults, namely
no DC output, and noisy output.
To assist tracing DC Power Supply problems, the wiring used to connect the
various printed circuit assemblies and DC Powered components and the
associated test points on the relay board follow a standard color-coding scheme as
defined in the following table.

11.6.3. I2C BUS
Operation of the I2C bus can be verified by observing the behavior of D1 on the
Relay Board in conjunction with the performance of the front panel display.
Assuming that the DC power supplies are operating properly and the wiring is
intact, the I2C bus is operating properly if:
D1 on the relay board is flashing, or;
D1 is not flashing but pressing a button on the touchscreen results in a
change to the display.
11.6.4. TOUCHSCREEN INTERFACE
Verify the functioning of the touchscreen by observing the display when pressing
a touchscreen control button. Assuming that there are no wiring problems and
that the DC power supplies are operating properly, if pressing a control button on
the display does not change the display, any of the following may be the problem:
The touchscreen controller may be malfunctioning.
The internal USB bus may be malfunctioning.
You can verify this failure by logging on to the instrument using APICOM or a
terminal program to any of the communications ports. If the analyzer responds to

remote commands and the display changes accordingly, the touchscreen interface
may be faulty.
11.6.5. LCD DISPLAY MODULE
Verify the functioning of the front panel display by observing it when power is
applied to the instrument. Assuming that there are no wiring problems and that
the DC power supplies are operating properly, the display screen should light and
show the splash screen with logo and other indications of its state as the CPU
goes through its initialization process.
11.6.6. RELAY BOARD
The relay board PCA (04135) can be most easily checked by observing the
condition of the its status LEDs on the relay board, as described in Section
12.6.3.1, and the associated output when toggled on and off through signal I/O
function in the diagnostic menu, See Section 11.1.3.
1. If the front panel display responds to key presses and D1 on the relay board
is NOT flashing then either the wiring between the Keyboard and the relay
board is bad, or the relay board is bad.
2. If D1 on the relay board is flashing and the status indicator for the output in
question (heater power etc.) toggles properly using the signal I/O function,
then the associated control device on the relay board is bad. (Several of the
control devices are in sockets and can be easily replaced).
11.6.7. SENSOR ASSEMBLY
Both the CO2 and O2 sensors have no user serviceable parts.
11.6.8. PRESSURE/FLOW SENSOR ASSEMBLY
The pressure/flow sensor PCA can be checked with a Voltmeter using the
following procedure which, assumes that the wiring is intact, and that the
motherboard and the power supplies are operating properly:

1. For Pressure related problems:
Troubleshooting and Service
Measure the voltage across C1 it should be 5 ± 0.25 VDC.
If not then the board is bad.
Measure the voltage across TP4 and TP1.
With the sample pump disabled it should be 4500 mV ±250 mV.
With the pump energized it should be approximately 200 mV less. If
not, then S1, the pressure transducer is bad, the board is bad, or
there is a pneumatic failure preventing the pressure transducer from
sensing the absorption cell pressure properly.
2. For flow related problems:
Measure the voltage across TP2 and TP1 it should be 10 ±0.25 VDC.
If not then the board is bad.
With flow stopped (sample inlet blocked) the voltage should be
approximately 1V.
If the voltage is incorrect, the flow sensor is bad, the board is bad or
there is a leak upstream of the sensor.

motherboard is to use the Signal I/O function under the DIAG menu to check the
two A/D reference voltages and input signals that can be easily measured with a
voltmeter.

bad.
2. Choose
a
parameter in the Signal I/O function such as
SAMPLE_PRESSURE or SAMPLE_FLOW.
Compare these voltages at their origin (see interconnect drawing PN
06407 and interconnect list PN 06294 in Appendix D) with the voltage
displayed through the signal I/O function.
If the wiring is intact but there is a large difference between the measured
and displayed voltage (±10 mV) then the motherboard is bad.
11.6.9.2. ANALOG OUTPUTS: CURRENT LOOP
To verify that the analog outputs with the optional current mode output are
working properly, connect a 250 ohm resistor across the outputs and use a
voltmeter to measure the output as described in Section 5.10.3.4.
For each step the output should be within 1% of the nominal value listed in the

11.6.10. CPU
There are two major types of failures associated with the CPU board: complete
failure and a failure associated with the Disk-On-Module (DOM) on the CPU
board. If either of these failures occurs, contact the factory.
For complete failures, assuming that the power supplies are operating properly
and the wiring is intact, the CPU is faulty if on power-on, the watchdog LED on
the motherboard is not flashing.
In some rare circumstances, this failure may be caused by a bad IC on the
motherboard, specifically U57, the large, 44 pin device on the lower right hand
side of the board. If this is true, removing U57 from its socket will allow the
instrument to start up but the measurements will be invalid.
If the analyzer stops during initialization (the front panel display shows a fault or
warning message), it is likely that the DOM, the firmware or the configuration
and data files have been corrupted.

11.6.11.1. GENERAL RS-232 TROUBLESHOOTING
Teledyne API analyzers use the RS-232 communications protocol to allow the
instrument to be connected to a variety of computer-based equipment. RS-232
has been used for many years and as equipment has become more advanced,
connections between various types of hardware have become increasingly
difficult. Generally, every manufacturer observes the signal and timing
requirements of the protocol very carefully.
Problems with RS-232 connections usually center around four general areas:

11.6.11.2. TROUBLESHOOTING ANALYZER/MODEM OR TERMINAL OPERATION
These are the general steps for troubleshooting problems with a modem
connected to a Teledyne API analyzer.
1. Check cables for proper connection to the modem, terminal or computer.
2. Check to make sure the DTE-DCE is in the correct position as described in
Section 6.1.
4. Verify that the Ready to Send (RTS) signal is at logic high. The T803 sets
pin 7 (RTS) to greater than 3 volts to enable modem transmission.
5. Make sure the BAUD rate, word length, and stop bit settings between modem
and analyzer match, See Section 8.3.
6. Use the RS-232 test function to send “w” characters to the modem, terminal
or computer; See Section 8.3.
7. Get your terminal, modem or computer to transmit data to the analyzer
(holding down the space bar is one way); the green LED should flicker as the
instrument is receiving data.
8. Make sure that the communications software or terminal emulation software
is functioning properly.

11.7. REPAIR PROCEDURES
This contains procedures that might need to be performed on rare occasions when
a major component of the analyzer requires repair or replacement.
11.7.1. REPAIRING SAMPLE FLOW CONTROL ASSEMBLY
The critical flow orifice is housed in the flow control assembly (Teledyne API PN
001760400) located on the top of the optical bench. A sintered filter protects the
jewel orifice so it is unusual for the orifice to need replacing, but if it does, or the
filter needs replacement please use the following procedure (see the Spare Parts
list in Appendix B for part numbers and kits):
1. Turn off power to the analyzer.
3. Disconnect the pneumatic connection from the flow assembly and the
assembly from the pump.
4. Remove the fitting and the components as shown in the exploded view
below.
5. Replace the o-rings (PN OR0000001) and the sintered filter (PN FL0000001).
6. If replacing the critical flow orifice itself (PN 000940700), make sure that the
side with the colored window (usually red) is facing downstream to the flow
gas flow.
7. Apply new Teflon® tape to the male connector threads
8. Re-assemble in reverse order.

COULD DAMAGE INSTRUMENT AND VOID WARRANTY
ATTENTION
Servicing of circuit components requires electrostatic discharge
protection, i.e. ESD grounding straps, mats and containers. Failure
to use ESD protection when working with electronic assemblies will
information on preventing ESD damage.
Replacing the Disk-on-Module (DOM) will cause loss of all DAS data; it may
also cause loss of some instrument configuration parameters unless the
replacement DOM carries the exact same firmware version. Whenever changing
the version of installed software, the memory must be reset. Failure to ensure that
memory is reset can cause the analyzer to malfunction, and invalidate
measurements. After the memory is reset, the A/D converter must be re-
calibrated, and all information collected in Step 1 below must be re-entered
before the instrument will function correctly. Also, zero and span calibration
should be performed.
1. Document all analyzer parameters that may have been changed, such as
range, auto-cal, analog output, serial port and other settings before replacing
the DOM
2. Turn off power to the instrument, fold down the rear panel by loosening the
mounting screws.
3. When looking at the electronic circuits from the back of the analyzer, locate
the Disk-on-Module in the right-most socket of the CPU board.

4. The DOM should carry a label with firmware revision, date and initials of the
programmer.
5. Remove the nylon standoff clip that mounts the DOM over the CPU board,
and lift the DOM off the CPU. Do not bend the connector pins.
6. Install the new Disk-on-Module, making sure the notch at the end of the chip
matches the notch in the socket.
7. It may be necessary to straighten the pins somewhat to fit them into the
socket. Press the chip all the way in.
8. Close the rear panel and turn on power to the machine.
9. If the replacement DOM carries a firmware revision, re-enter all of the setup
information.
11.8. FREQUENTLY ASKED QUESTIONS (FAQ’S)
The following is a list from the Teledyne API’s Technical Support Department of
the most commonly asked questions relating to the analyzer.
QUESTION
ANSWER
During certain types of adjustments or configuration operations, the
ENTR button will disappear if you select a setting that is nonsensical
Why does the ENTR button
sometimes disappear on the
Front Panel Display?
(such as trying to set the 24-hour clock to 25:00:00) or out of the
allowable range for that parameter (such as selecting a DAS HOLD
OFF period of more than 20 minutes). Once you adjust the setting in
question to an allowable value, the ENTR button will re-appear.
The analyzer disables these buttons when the expected span or zero
value entered by the users is too different from the gas concentration
actual measured value. This is to prevent the accidental recalibration
of the analyzer to an out-of-range response curve. EXAMPLE: The
span set point is 16% but gas concentration being measured is only
5%.
Why is the ZERO or SPAN
button not displayed during
calibration?
Press the CONC button found under the CAL button of the main
SAMPLE display menus to enter the expected CO2 span
How do I enter or change the
value of my Span Gas?
Why does the analyzer not
respond to span gas?
This most commonly occurs for one of the following reasons: - A
difference in circuit ground between the analyzer and the data logger
- A wiring problem or a scale problem with the input to the data
logger. The analog outputs can be manually adjusted to compensate
outputs are not calibrated, which can happen after a firmware
upgrade. - Both the electronic scale and offset of the analog outputs
as the metering device during calibrations procedures.
What shall I do if the
concentration on the
instrument's front panel display
does not match the value
recorded or displayed on my
data logger even if both
instruments are properly
calibrated?

12. PRINCIPLES OF OPERATION
The T803 analyzer is a microprocessor-controlled analyzer that determines the
percent concentration of carbon dioxde (CO2) and molecular oxygen (O2) in a
sample gas drawn through the instrument. It uses a paramagnetic sensor that
relies on the relatively high reactivity of O2 molecules to magnetic fields to
generate a current that is proportional to the amount of O2 present in the sensor
chamber. The carbon dioxide measurement is achieved using infrared absorption
technology.
Calibration of the instrument is performed in software and does not require
physical adjustments to the instrument. During calibration the microprocessor
measures the current state of both Sensor outputs and various other physical
parameters of the instrument and stores them in memory. The microprocessor
uses these calibration values, measurements made on the sample gas along with
data regarding the current temperature and pressure of the gas to calculate the
final concentrations.
12.1. O2 SENSOR
12.1.1. MAGNETIC PROPERTIES OF O2 GAS
Molecular oxygen, O2, displays a particularly strong susceptibility to the effect of
magnetic fields. This is due to the behavior of the electrons of the two oxygen
atoms that make up the O2 molecule.
When the electrons in an orbital are paired, they spin in opposite directions from
each other thereby canceling any magnetic field effects. On the other hand,
unpaired electrons, such as those of an O2 molecule, spin in the same direction as
each other, increasing the aggregate magnetic field.
12.1.2. PARAMAGNETIC MEASUREMENT OF O2
The type of paramagnetic sensor used in the T803 analyzer is called a magneto-
mechanical sensor. This type of sensor consists of a small dumbbell-shaped body
(a sphere on either end) made of glass and filled with a gas of negative
paramagnetic characteristic (in this case, N2). The dumbbell body is suspended
on a platinum fiber within the magnetic field of a permanent magnet, in such a
way that it is free to rotate. Because the N2 inside the spheres has a small opposite
magnetic charge from the field of the permanent magnet, the dumbbell’s resting
(neutral) position is slightly deflected away from the strong point of the field.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
Figure 12-1:
Paramagnetic O2 Sensor Design
When sample gas containing oxygen flows into the magneto-mechanical sensor,
the O2 molecules are drawn toward the strong point of the magnetic field. This
causes the N2 filled spheres to deflect even more so that the suspended dumbbell
body pivots on the platinum wire. The more O2 present the further the dumbbell
body is deflected from its neutral position.
The position of the dumbbell is detected by a pair of photocells that receive a
light beam reflected from a mirror attached to the center of the dumbbell body.
As the dumbbell body pivots, the angle of the reflected light beam on the
photocells changes. The resulting potential difference creates a current.

Principles of Operation
This current is passed to a feedback loop, which generates a second current to a
wire winding (in effect, a small DC electric motor) mounted on the suspended
mirror. The more O2 present, the more the dumbbell and its attached mirror
moves and the more current is needed to move the dumbbell back to it’s zero
position. Finally, sensor measures the amount of current generated by the
feedback control loop which is directly proportional to the concentration of
oxygen within the sample gas mixture.
12.2. CO2 SENSOR
12.2.1. NDIR MEASUREMENT OF CO2
The CO2 sensor is a silicon based Non-Dispersive Infrared (NDIR) sensor. It uses
a single-beam, dual wavelength measurement method.
An infrared source at one end of the measurement chamber emits IR radiation
into the sensor’s measurement chamber where light at the 4.3 μm wavelength is
partially absorbed by any CO2 present. A special light filter called a Fabry-Perot
Interferometer (FPI) is electronically tuned so that only light at the absorption
wavelength of CO2 is allowed to pass and be detected by the sensor’s IR detector.
A reference measurement is made by electronically shifting the filter band pass
wavelength so that no IR at the CO2 absorption wavelength is let through.
Figure 12-3.
CO2 Sensor Theory of Operation
The sensor computes the ratio between the reference signal and the measurement
signal to determine the degree of light absorbed by CO2 present in the sensor

chamber. This dual wavelength method of measuring CO2 allows the instrument
to compensate for ancillary effects like sensor aging and contamination.
12.3. OPERATION WITHIN THE T803 ANALYZER
Operationally, both the CO2 and O2 sensors are transparently integrated into the
core analyzer operation. All functions can be viewed or accessed through the
front panel.
The CO2 concentration is displayed in the upper right-hand corner, alternating
with O2 concentration.
Test functions for the slope and offset of CO2 and of O2 are viewable from the
front panel along with the analyzer’s other test functions.
Calibration of each sensor is performed via the front panel CAL. See
Stability of each sensor can be viewed via the front panel (see Section 9).
12.3.1.1. ELECTRONIC OPERATION OF THE CO2 SENSOR
The CO2 PCA is powered by 12 VDC from the analyzer via the relay card, which
outputs a 0-5 VDC analog signal to the analyzer’s CPU via the motherboard that
corresponds to the concentration of CO2 measured by the probe.

12.4. PNEUMATIC OPERATION
CAUTION
GENERAL SAFETY HAZARD
IT IS IMPORTANT THAT THE SAMPLE AIRFLOW SYSTEM IS BOTH LEAK-TIGHT AND NOT
PRESSURIZED OVER AMBIENT PRESSURE.
Regular leak checks should be performed on the analyzer as described in the maintenance
schedule, 10.1.
Procedures for correctly performing leak checks can be found in Section 10.3.3
In pneumatic operation an internal pump creates a vacuum that draws sample gas
into the analyzer. Normally the analyzer is operated with its inlet near ambient
pressure either because the sample is directly drawn at the inlet or a small vent is
installed at the inlet when the sample is delivered under pressure. There are
several advantages to this “pull through” configuration.
First the pumping process heats and compresses the sample complicating
the measurement process. Both heat and pressure affect the accuracy of
gas measurements.
Additionally, certain physical parts of the pump itself are made of materials
that might chemically react with the sample gas.

Principles of Operation
Teledyne API T803 CO2/O2 Analyzer Operation Manual
12.5. FLOW RATE CONTROL
To maintain a constant flow rate of the sample gas through the instrument, the
T803 uses a special flow control assembly located in the exhaust gas line just
before the optional internal pump or connected to the rear panel if using an
external pump. These assemblies consist of:
A critical flow orifice.
Two o-rings: Located just before and after the critical flow orifice, the o-rings
seal the gap between the walls of assembly housing and the critical flow
orifice.
A spring: Applies mechanical force needed to form the seal between the o-
rings, the critical flow orifice and the assembly housing.
A sintered filter: Removes particulates to prevent clogging the orifice
12.5.1. CRITICAL FLOW ORIFICE
The most important component of this flow control assembly is the critical flow
orifice.
Critical flow orifices are a remarkably simple way to regulate stable gas flow
rates. They operate without moving parts by taking advantage of the laws of fluid
dynamics. By restricting the flow of gas though the orifice, a pressure differential
is created. This pressure differential combined with the action of the analyzer’s
pump draws the gas through the orifice.
As the pressure on the downstream side of the orifice (the pump side) continues
to drop, the speed that the gas flows though the orifice continues to rise. Once
the ratio of upstream pressure to downstream pressure is greater than 2:1, the
velocity of the gas through the orifice reaches the speed of sound. As long as that
ratio stays at least 2:1 the gas flow rate is unaffected by any fluctuations, surges,
or changes in downstream pressure because such variations only travel at the
speed of sound themselves and are therefore cancelled out by the sonic
shockwave at the downstream exit of the critical flow orifice.

Flow Control Assembly & Critical Flow Orifice
The actual flow rate of gas through the orifice (volume of gas per unit of time),
depends on the size and shape of the aperture in the orifice. The larger the hole,
the more gas molecules, moving at the speed of sound, pass through the orifice.
Because the flow rate of gas through the orifice is only related to the minimum
2:1 pressure differential and not absolute pressure the flow rate of the gas is also
unaffected by degradations in pump efficiency due to age.
The critical flow orifice used in the T803 is designed to provide a flow rate of
120 cm3/min.
12.5.2. PARTICULATE FILTER
The T803 Analyzer comes equipped with a 47 mm diameter, Teflon, particulate
filter with a 1 micron pore size. The filter is accessible through the front panel,
which folds down to allow access, and should be changed according to the
suggested maintenance schedule described in
12.5.3. PNEUMATIC SENSORS
12.5.3.1. SAMPLE PRESSURE SENSOR
An absolute value pressure transducer plumbed to the outlet of the sample
chamber is used to measure sample pressure. The output of the sensor is used to
compensate the concentration measurement for changes in ambient air pressure.
This sensor is mounted to a printed circuit board with the sample flow sensor on
the sample chamber; see the following section and Figure 3-5.
12.5.3.2. SAMPLE FLOW SENSOR
A thermal-mass flow sensor is used to measure the sample flow through the
analyzer. The sensor is calibrated at the factory with ambient air or N2, but can
be calibrated to operate with samples consisting of other gases such as O2. This

12.6. ELECTRONIC OPERATION
12.6.1. OVERVIEW
Figure 10-9 shows a block diagram of the major electronic components of the
T803.
The core of the analyzer is a microcomputer (CPU) that controls various internal
processes, interprets data, makes calculations, and reports results using
specialized firmware developed by Teledyne API. It communicates with the user
as well as receives data from and issues commands to a variety of peripheral
devices via a separate printed circuit assembly called the motherboard.
The motherboard collects data, performs signal conditioning duties and routes
incoming and outgoing signals between the CPU and the analyzer’s other major
components.
A variety of sensors report the physical and operational status of the analyzer’s
major components, again through the signal processing capabilities of the
motherboard. These status reports are used as data for the gas concentration
calculation and as trigger events for certain control commands issued by the CPU.
They are stored in memory by the CPU and in most cases can be viewed but the
user via the front panel display.
The CPU communicates with the user and the outside world in several ways
Through the analyzer’s touchscreen and LCD display over a clocked, digital,
serial I/O bus (using a protocol called I2C);
RS-232 & RS-485 Serial I/O channels via Ethernet, Modbus®, APICOM or a
terminal emulation program;
Various DCV and DCA analog outputs, and
Several sets of Digital I/O channels.
Finally, the CPU issues commands via a series of relays and switches (also over
the I2C bus) located on a separate printed circuit assembly to control the function
of key electromechanical devices such as heaters.

CPU Card
The CPU includes two types of non-volatile data storage: an embedded 2MB
flash chip and a Disk on Module (DOM).
12.6.2.1. DISK-ON-MODULE (DOM)
The DOM is a 44-pin IDE flash disk with a storage capacity up to 128MB. It is
used to store the computer’s operating system, the Teledyne API firmware, and
most of the operational data generated by the analyzer’s internal data acquisition
reading/writing to or from the DOM.
12.6.2.2. FLASH CHIP
This non-volatile, embedded flash chip includes 2MB of storage for calibration
data as well as a backup of the analyzer configuration. Storing these key data on a
less heavily accessed chip significantly decreases the chance of data corruption.
In the unlikely event that the flash chip should fail, the analyzer will continue to
operate with just the DOM. However, all configuration information will be lost,
requiring the unit to be recalibrated.

12.6.3. RELAY BOARD
The CPU issues commands via a series of relays and switches located on a
separate printed circuit assembly, called the relay PCA, to control the function of
key electromechanical devices such as heaters. The relay PCA receives
instructions in the form of digital signals over the I2C bus, interprets these digital
instructions and activates its various switches and relays appropriately.
The relay PCA is located in the right-rear quadrant of the analyzer and is
mounted vertically on the backside of the same bracket as the instrument’s DC
power supplies.

At low magnetic field strengths levels, paramagnetic molecules follow Curie's
law to good approximation, which indicates that the susceptibility of
paramagnetic materials is inversely proportional to their temperature.
To minimize the effects of temperature variations on the O2 concentration
measurement the parametric sensor is raised to a high temperature level, 50C. A
cartridge heater implanted into the sensor is the heat source. The temperature of
the sensor is measured by a thermistor also inserted into the sensor body.

12.6.5. MOTHERBOARD
This printed circuit assembly provides a multitude of functions including, A/D
conversion, digital input/output, PC-104 to I2C translation, temperature sensor
signal processing, and serves as a pass-through for the RS-232 and RS-485
signals.
12.6.5.1. A TO D CONVERSION
Analog signals, such as the voltages received from the analyzer’s various sensors,
are converted into digital signals that the CPU can understand and manipulate by
the analog to digital converter (A/D). Under the control of the CPU, this
functional block selects a particular signal input (e.g. BOX TEMP) and then
converts the selected voltage into a digital word.
The A/D consists of a voltage-to-frequency (V-F) converter, a programmable
logic device (PLD), three multiplexers, several amplifiers and some other
associated devices. The V-F converter produces a frequency proportional to its
input voltage. The PLD counts the output of the V-F during a specified time
period, and sends the result of that count, in the form of a binary number, to the
CPU.
The A/D can be configured for several different input modes and ranges but in
the T803 the A/D is used in uni-polar mode with a +5 V full scale. The converter
includes a 1% over and under-range. This allows signals from –0.05 V to +5.05
V to be fully converted.
For calibration purposes, two reference voltages are supplied to the A/D
converter: Reference Ground and +4.096 VDC. During calibration, the device
measures these two voltages, outputs their digital equivalent to the CPU. The
CPU uses these values to compute the converter’s offset and slope and uses these
factors for subsequent conversions.
12.6.5.2. SENSOR INPUTS
The key analog sensor signals are coupled to the A/D through the master
multiplexer from two connectors on the motherboard. 100K terminating resistors
on each of the inputs prevent cross talk from appearing on the sensor signals.
SAMPLE PRESSURE AND FLOW
These are analog signals from two sensors that measure the pressure and flow rate
of the gas stream at the outlet of the sample chamber. This information is used in
two ways. First, the sample pressure is used by the CPU to calculate O2
Concentration. Second, the pressure and flow rate are monitored as a test
function to assist the user in predicting and troubleshooting failures.
12.6.5.3. THERMISTOR INTERFACE
This circuit provides excitation, termination and signal selection for several
negative-coefficient, thermistor temperature sensors located inside the analyzer;
there is a thermistor for the O2 sample chamber housing, which reports the
218

Principles of Operation
current temperature of the chamber housing to the CPU as part of the bench
heater control loop. Another thermistor, attached to the motherboard, measures
the analyzer’s inside temperature (box temperature). This information is stored
by the CPU and can be viewed by the user for troubleshooting purposes via the
12.6.5.4. ANALOG OUTPUTS
The analyzer comes equipped with four analog outputs: A1, A2, A3 and A4.
The type of data and electronic performance of these outputs are configurable by
A/D converter through a Loop-back circuit. This permits the voltage outputs to
be calibrated by the CPU without need for any additional tools or fixtures.
12.6.5.5. EXTERNAL DIGITAL I/O
This External Digital I/O performs status outputs and control inputs.
STATUS OUTPUTS
Logic-Level voltages are output through an optically isolated 8-pin connector
located on the rear panel of the analyzer. These outputs convey good/bad and
on/off information about certain analyzer conditions. They can be used to
interface with certain types of programmable devices (See Section 3.3.1.4).
CONTROL INPUTS
By applying +5VDC power supplied from an external source such as a PLC or
contact closures on the rear panel.
12.6.6. I2C DATA BUS
An I2C data bus is used to communicate data and commands between the CPU
and the touchscreen interface and the relay board. I2C is a two-wire, clocked,
digital serial I/O bus that is used widely in commercial and consumer electronic
systems. A transceiver on the motherboard converts data and control signals
from the PC-104 bus to I2C. The data is then fed to the keyboard/display
interface and finally onto the relay board.
Interface circuits on the keyboard/display interface and relay boards convert the
I2C data to parallel inputs and outputs. An additional, interrupt line from the
keyboard to the motherboard allows the CPU to recognize and service key
presses on the keyboard.
POWER UP CIRCUIT
This circuit monitors the +5V power supply during start-up and sets the Analog
outputs, external digital I/O ports, and I2C circuitry to specific values until the
CPU boots and the instrument software can establish control.

12.6.7. POWER SUPPLY / CIRCUIT BREAKER
The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50Hz
or 60Hz. Individual units are set up at the factory to accept any combination of
through a standard IEC 320 power receptacle located on the rear panel of the
instrument. From there it is routed through the On/Off switch located in the
lower right corner of the Front Panel. A 6.75 Amp circuit breaker is built into the
ON/OFF Switch.
AC power is distributed directly to the sample gas pump.
AC Line power is stepped down and converted to DC power by two DC power
supplies. One supplies +12 VDC, while a second supply provides +5 VDC and
±15 VDC for logic and analog circuitry. All DC voltages are distributed via the
relay board.
CAUTION
GENERAL SAFETY HAZARD
Should the AC power circuit breaker trip, investigate and correct the condition causing
this situation before turning the analyzer back on.

12.6.10. ADAPTIVE FILTER
Unlike other analyzers that average the output signal over a fixed time period, the
T803 averages over a set number of samples, where each sample is 1 second.
This technique is known as boxcar averaging. During operation, the software
automatically switches between two different length filters based on the
conditions at hand. Once triggered, the short filter remains engaged for a fixed
time period to prevent chattering.
Two conditions must be simultaneously met to switch to the short filter. First, the
instantaneous concentration must exceed the average in the long filter by a fixed
amount. Second, the instantaneous concentration must exceed the average in the
long filter by a portion, or percentage, of the average in the long filter.
If necessary, these boxcar lengths as well as the threshold levels can be altered
but with corresponding tradeoffs in rise time and signal-to-noise ratio (contact
Teledyne API Technical Support for more information).

12.6.11. CALIBRATION - SLOPE AND OFFSET
Calibration of the analyzer is performed exclusively in software.
During instrument calibration the user enters expected values for span via the
front panel touchscreen; values are not entered during a zero operation,
commanding the instrument to make readings of calibrated sample gases for both
levels. The readings taken are adjusted, linearized, and compared to the expected
values. With this information the software computes values for instrument slope
and offset and stores these values in memory for use in calculating concentrations
of the sample gas.
The instrument slope and offset values recorded during the last calibration are
available for viewing from the from the front panel (See Section 3.5.1)
12.6.12. TEMPERATURE AND PRESSURE COMPENSATION
Changes in ambient pressure can have a noticeable effect on the CO2 and O2
concentration calculations. To account for this, the T803 software includes a
feature which allows the instrument to compensate both CO2 and O2 calculations
based on changes in ambient pressure. Both sensors are housed inside
temperature controlled manifolds. This minimizes temperature effects on the
measured concentrations.
12.6.13. INTERNAL DATA ACQUISITION SYSTEM (DAS)
The DAS is designed to implement predictive diagnostics that stores trending
data for users to anticipate when an instrument will require service. Large
amounts of data can be stored in non-volatile memory and retrieved in plain text
format for further processing with common data analysis programs. The DAS
has a consistent user interface in all Teledyne API analyzers. New data
parameters and triggering events can be added to the instrument as needed.
Depending on the sampling frequency and the number of data parameters the
DAS can store several months of data, which are retained even when the
instrument is powered off or a new firmware is installed. The DAS permits users
to access the data through the instrument’s front panel or the remote interface.
The latter can automatically download stored data for further processing. For
information on using the DAS, refer to Section 7.1

13. A PRIMER ON ELECTRO-STATIC DISCHARGE
Teledyne API considers the prevention of damage caused by the discharge of
static electricity to be extremely important part of making sure that your analyzer
continues to provide reliable service for a long time. This section describes how
static electricity occurs, why it is so dangerous to electronic components and
assemblies as well as how to prevent that damage from occurring.
13.1. HOW STATIC CHARGES ARE CREATED
Modern electronic devices such as the types used in the various electronic
assemblies of your analyzer, are very small, require very little power and operate
very quickly. Unfortunately, the same characteristics that allow them to do these
things also make them very susceptible to damage from the discharge of static
electricity. Controlling electrostatic discharge begins with understanding how
electro-static charges occur in the first place.
Static electricity is the result of something called triboelectric charging which
happens whenever the atoms of the surface layers of two materials rub against
each other. As the atoms of the two surfaces move together and separate, some
electrons from one surface are retained by the other.

Triboelectric Charging
If one of the surfaces is a poor conductor or even a good conductor that is not
grounded, the resulting positive or negative charge cannot bleed off and becomes
trapped in place, or static. The most common example of triboelectric charging
happens when someone wearing leather or rubber soled shoes walks across a
nylon carpet or linoleum tiled floor. With each step, electrons change places and
the resulting electro-static charge builds up, quickly reaching significant levels.
Pushing an epoxy printed circuit board across a workbench, using a plastic
handled screwdriver or even the constant jostling of StyrofoamTM pellets during
shipment can also build hefty static charges

13.2. HOW ELECTRO-STATIC CHARGES CAUSE DAMAGE
Damage to components occurs when these static charges come into contact with
an electronic device. Current flows as the charge moves along the conductive
circuitry of the device and the typically very high voltage levels of the charge
overheat the delicate traces of the integrated circuits, melting them or even
vaporizing parts of them. When examined by microscope the damage caused by
electro-static discharge looks a lot like tiny bomb craters littered across the
landscape of the component’s circuitry.
News estimates that approximately 60% of device failures are the result of
damage due to electro-static discharge.

Potentially damaging electro-static discharges can occur:
Any time a charged surface (including the human body) discharges to a device.
Even simple contact of a finger to the leads of a sensitive device or assembly can
allow enough discharge to cause damage. A similar discharge can occur from a
charged conductive object, such as a metallic tool or fixture.

A Primer on Electro-Static Discharge
When static charges accumulated on a sensitive device discharges from the
device to another surface such as packaging materials, work surfaces, machine
surfaces or other device. In some cases, charged device discharges can be the
most destructive.
A typical example of this is the simple act of installing an electronic assembly
into the connector or wiring harness of the equipment in which it is to function.
If the assembly is carrying a static charge, as it is connected to ground a discharge
will occur.
Whenever a sensitive device is moved into the field of an existing electro-static
field, a charge may be induced on the device in effect discharging the field onto
the device. If the device is then momentarily grounded while within the
electrostatic field or removed from the region of the electrostatic field and
grounded somewhere else, a second discharge will occur as the charge is
transferred from the device to ground.
13.3. COMMON MYTHS ABOUT ESD DAMAGE
I didn’t feel a shock so there was no electro-static discharge: The human
nervous system isn’t able to feel a static discharge of less than 3500 volts. Most
devices are damaged by discharge levels much lower than that.
I didn’t touch it so there was no electro-static discharge: Electro Static charges
are fields whose lines of force can extend several inches or sometimes even feet
away from the surface bearing the charge.
It still works so there was no damage: Sometimes the damaged caused by
electro-static discharge can completely sever a circuit trace causing the device to
fail immediately. More likely, the trace will be only partially occluded by the
damage causing degraded performance of the device or worse, weakening the
trace. This weakened circuit may seem to function fine for a short time, but even
the very low voltage and current levels of the device’s normal operating levels
will eat away at the defect over time causing the device to fail well before its
designed lifetime is reached.
These latent failures are often the most costly since the failure of the equipment
in which the damaged device is installed causes down time, lost data, lost
productivity, as well as possible failure and damage to other pieces of equipment
or property.
Static Charges can’t build up on a conductive surface: There are two errors in
this statement.
Conductive devices can build static charges if they are not grounded. The charge
will be equalized across the entire device, but without access to earth ground,
they are still trapped and can still build to high enough levels to cause damage
when they are discharged.
A charge can be induced onto the conductive surface and/or discharge triggered
in the presence of a charged field such as a large static charge clinging to the
surface of a nylon jacket of someone walking up to a workbench.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
As long as my analyzer is properly installed, it is safe from damage caused
by static discharges: It is true that when properly installed the chassis ground of
your analyzer is tied to earth ground and its electronic components are prevented
from building static electric charges themselves. This does not prevent
discharges from static fields built up on other things, like you and your clothing,
from discharging through the instrument and damaging it.
13.4. BASIC PRINCIPLES OF STATIC CONTROL
It is impossible to stop the creation of instantaneous static electric charges. It is
not, however difficult to prevent those charges from building to dangerous levels
or prevent damage due to electro-static discharge from occurring.
13.4.1. GENERAL RULES
Only handle or work on all electronic assemblies at a properly set up ESD station.
Setting up an ESD safe workstation need not be complicated. A protective mat
properly tied to ground and a wrist strap are all that is needed to create a basic
anti-ESD workstation.
Protective Mat
Wrist Stra
Ground Point
Figure 13-2:
Basic Anti-ESD Workbench
For technicians that work in the field, special lightweight and portable anti-ESD
kits are available from most suppliers of ESD protection gear. These include
everything needed to create a temporary anti-ESD work area anywhere.
Always wear an Anti-ESD wrist strap when working on the electronic
assemblies of your analyzer. An anti-ESD wrist strap keeps the person wearing
it at or near the same potential as other grounded objects in the work area and
allows static charges to dissipate before they can build to dangerous levels. Anti-
ESD wrist straps terminated with alligator clips are available for use in work
areas where there is no available grounded plug.
Also, anti-ESD wrist straps include a current limiting resistor (usually around one
meg-ohm) that protects you should you accidentally short yourself to the
instrument’s power supply.
Simply touching a grounded piece of metal is insufficient. While this may
temporarily bleed off static charges present at the time, once you stop touching
the grounded metal new static charges will immediately begin to re-build. In
some conditions, a charge large enough to damage a component can rebuild in
just a few seconds.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
A Primer on Electro-Static Discharge
Always store sensitive components and assemblies in anti-ESD storage bags
or bins: Even when you are not working on them, store all devices and
assemblies in a closed anti-Static bag or bin. This will prevent induced charges
from building up on the device or assembly and nearby static fields from
discharging through it.
Use metallic anti-ESD bags for storing and shipping ESD sensitive
components and assemblies rather than pink-poly bags. The famous, pink-
poly bags are made of a plastic that is impregnated with a liquid (similar to liquid
laundry detergent) which very slowly sweats onto the surface of the plastic
creating a slightly conductive layer over the surface of the bag.
While this layer may equalizes any charges that occur across the whole bag, it
does not prevent the build up of static charges. If laying on a conductive,
grounded surface, these bags will allow charges to bleed away but the very
charges that build up on the surface of the bag itself can be transferred through
the bag by induction onto the circuits of your ESD sensitive device. Also, the
liquid impregnating the plastic is eventually used up after which the bag is as
useless for preventing damage from ESD as any ordinary plastic bag.
Anti-Static bags made of plastic impregnated with metal (usually silvery in color)
provide all of the charge equalizing abilities of the pink-poly bags but also, when
properly sealed, create a Faraday cage that completely isolates the contents from
discharges and the inductive transfer of static charges.
Storage bins made of plastic impregnated with carbon (usually black in color) are
also excellent at dissipating static charges and isolating their contents from field
effects and discharges.
Never use ordinary plastic adhesive tape near an ESD sensitive device or to
close an anti-ESD bag. The act of pulling a piece of standard plastic adhesive
tape, such as Scotch® tape, from its roll will generate a static charge of several
thousand or even tens of thousands of volts on the tape itself and an associated
field effect that can discharge through or be induced upon items up to a foot
away.
13.4.2. BASIC ANTI-ESD PROCEDURES FOR ANALYZER REPAIR AND
MAINTENANCE
13.4.2.1. WORKING AT THE INSTRUMENT RACK
When working on the analyzer while it is in the instrument rack and plugged into
a properly grounded power supply
1. Attach you anti-ESD wrist strap to ground before doing anything else.
Use a wrist strap terminated with an alligator clip and attach it to a bare metal
portion of the instrument chassis.
This will safely connect you to the same ground level to which the instrument
and all of its components are connected.
2. Pause for a second or two to allow any static charges to bleed away.

Teledyne API T803 CO2/O2 Analyzer Operation Manual
3. Open the casing of the analyzer and begin work. Up to this point, the closed
metal casing of your analyzer has isolated the components and assemblies
inside from any conducted or induced static charges.
4. If you must remove a component from the instrument, do not lay it down on a
non-ESD preventative surface where static charges may lie in wait.
5. Only disconnect your wrist strap after you have finished work and closed the
case of the analyzer.
13.4.2.2. WORKING AT AN ANTI-ESD WORK BENCH
When working on an instrument of an electronic assembly while it is resting on a
anti-ESD workbench
1. Plug you anti-ESD wrist strap into the grounded receptacle of the work
station before touching any items on the work station and while standing at
least a foot or so away. This will allow any charges you are carrying to bleed
away through the ground connection of the workstation and prevent
discharges due to field effects and induction from occurring.
2. Pause for a second or two to allow any static charges to bleed away.
3. Only open any anti-ESD storage bins or bags containing sensitive devices or
assemblies after you have plugged your wrist strap into the workstation.
Lay the bag or bin on the workbench surface.
Before opening the container, wait several seconds for any static charges on
the outside surface of the container to be bled away by the workstation’s
grounded protective mat.
4. Do not pick up tools that may be carrying static charges while also touching
or holding an ESD sensitive Device.
Only lay tools or ESD-sensitive devices and assemblies on the conductive
surface of your workstation. Never lay them down on any non-ESD
preventative surface.
5. Place any static sensitive devices or assemblies in anti-static storage bags or
bins and close the bag or bin before unplugging your wrist strap.
6. Disconnecting your wrist strap is always the last action taken before leaving
the workbench.
Transferring Components from Rack to Bench and Back
When transferring a sensitive device from an installed Teledyne API analyzer
to an Anti-ESD workbench or back:
7. Follow the instructions listed above for working at the instrument rack and
workstation.
8. Never carry the component or assembly without placing it in an anti-ESD bag
or bin.
9. Before using the bag or container allow any surface charges on it to
dissipate:
If you are at the instrument rack, hold the bag in one hand while your wrist
strap is connected to a ground point.

If you are at an anti-ESD workbench, lay the container down on the
conductive work surface.
In either case wait several seconds.
10. Place the item in the container.
11. Seal the container. If using a bag, fold the end over and fastening it with anti-
ESD tape.
Folding the open end over isolates the component(s) inside from the effects
of static fields.
Leaving the bag open or simply stapling it shut without folding it closed
prevents the bag from forming a complete protective envelope around the
device.
12. Once you have arrived at your destination, allow any surface charges that
may have built up on the bag or bin during travel to dissipate:
Connect your wrist strap to ground.
If you are at the instrument rack, hold the bag in one hand while your wrist
strap is connected to a ground point.
If you are at a anti-ESD workbench, lay the container down on the conductive
work surface
In either case wait several seconds
13. Open the container.
13.4.2.3. OPENING SHIPMENTS FROM TELEDYNE API
Packing materials such as bubble pack and Styrofoam pellets are extremely
efficient generators of static electric charges. To prevent damage from ESD,
Teledyne API ships all electronic components and assemblies in properly sealed
ant-ESD containers.
Static charges will build up on the outer surface of the anti-ESD container during
shipping as the packing materials vibrate and rub against each other. To prevent
these static charges from damaging the components or assemblies being shipped
make sure that you:
Always unpack shipments from Teledyne API by:
1. Opening the outer shipping box away from the anti-ESD work area
2. Carry the still sealed ant-ESD bag, tube or bin to the anti-ESD work area
3. Follow steps 6 and 7 above when opening the anti-ESD container at the work
station
4. Reserve the anti-ESD container or bag to use when packing electronic
components or assemblies to be returned to Teledyne API
13.4.2.4. PACKING COMPONENTS FOR RETURN
Always pack electronic components and assemblies to be sent to Teledyne API
Technical Support in anti-ESD bins, tubes or bags.

CAUTION
ESD Hazard
DO NOT use pink-poly bags.
NEVER allow any standard plastic packaging materials to touch the electronic
component/assembly directly. This includes, but is not limited to, plastic bubble-
pack, Styrofoam peanuts, open cell foam, closed cell foam, and adhesive tape
DO NOT use standard adhesive tape as a sealer. Use ONLY anti-ESD tape
Never carry the component or assembly without placing it in an anti-ESD bag or
bin.
1. Before using the bag or container allow any surface charges on it to
dissipate:
If you are at the instrument rack, hold the bag in one hand while your wrist
strap is connected to a ground point.
If you are at an anti-ESD workbench, lay the container down on the
conductive work surface.
In either case wait several seconds.
2. Place the item in the container.
3. Seal the container. If using a bag, fold the end over and fastening it with anti-
ESD tape.
Folding the open end over isolates the component(s) inside from the effects
of static fields.
Leaving the bag open or simply stapling it shut without folding it closed
prevents the bag from forming a complete protective envelope around the
device.
Note
If you do not already have an adequate supply of anti-ESD bags or containers
available, Teledyne API’s Technical Support department will supply them
above for working at the instrument rack and workstation.
