1. INTRODUCTION, SPECIFICATIONS, APPROVALS, & COMPLIANCE

Teledyne API’s Model T300 and Model T300M are Gas Filter Correlation Carbon Monoxide Analyzers. These microprocessor-controlled analyzers are used to determine the concentration of carbon monoxide (CO) in a sample gas drawn through the instrument. The analysis method is based on the Beer-Lambert law, an empirical relationship that relates the absorption of light to the properties of the material through which the light is traveling over a defined distance. In this case the light is infrared radiation (IR) traveling through a sample chamber filled with gas bearing a varying concentration of CO.
The T300/T300M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.
Proprietary software allows configurable data acquisition capability that can be triggered conditionally or periodically, enabling operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends. Reports can be downloaded onto a USB flash drive or via the I/O ports. Operators can also view real-time graphing with one touch of the interface screen.

2.3 CONNECTIONS AND STARTUP

Note
WARNING – Electrical Shock Hazard
Do not operate with cover off.
CAUTION – Avoid Damage to the Instrument
This Section presents the electrical (Section 2.3.1) and pneumatic (Section 2.3.2) connections for setup and preparing for instrument operation.

2.3.1 ELECTRICAL CONNECTIONS

To maintain compliance with EMC standards, cable must be no longer than 3 meters for all I/O connections.
High Voltages are present inside the instrument’s case.
Power connection must have functioning ground connection.
Do not defeat the ground wire on power plug.
Turn off instrument power before disconnecting or connecting
electrical subassemblies.
Ensure that the AC power voltage matches the voltage indicated on the instrument’s model/specs label before plugging it into line power.
2.3.1.1 CONNECTING POWER
Attach the power cord between the instrument’s AC power connector and a power outlet capable of carrying at least the rated current at your AC voltage range and ensure that it is equipped with a functioning earth ground. It is important to adhere to all safety and cautionary messages.

2.3.1.3 CURRENT LOOP ANALOG OUTPUTS (OPTION 41) SETUP
If your analyzer had this option installed at the factory, there are no further connections to be made. Otherwise, it can be installed as a retrofit for each of the analog outputs. This option converts the DC voltage analog output to a current signal with 0-20 mA output current, which can be scaled to any set of limits within that 0-20 mA range. However, most current loop applications call for either 2-20 mA or 4-20 mA range. All current loop outputs have a +5% over-range. Ranges with the lower limit set to more than 1 mA (e.g., 2-20 or 4-20 mA) also have a -5% under-range.
LOOP OPTION
Figure 2-7 provides installation instructions and illustrates a sample configuration of one current output and two voltage outputs. Following Figure 2-7 are instructions for converting current loop analog outputs to standard 0-to-5 VDC outputs. To calibrate or adjust these outputs use the Setup>Analog Outputs menu (Section 2.5.8).

1. Turn off power to the analyzer.
2. If a recording device was connected to the output being modified, disconnect it.
3. Remove the top cover.
Remove the screws fastening the top cover to the unit (both sides).
Slide the cover back and lift straight up.

7. Reattach the top case to the analyzer.
The analyzer is now ready to have a voltage-sensing, recording device attached
to that output.
8. Calibrate the analog output in the Setup>Analog Outputs>Analog Output Cal menu.
2.3.1.4 CONNECTING THE STATUS OUTPUTS (DIGITAL OUTPUTS)
The 12-pin STATUS connector allows the digital status outputs to report analyzer conditions (configured through the Setup>Digital Outputs menu) 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 available at pin D (see Figure 2-8).
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY Most PLCs have internal provisions for limiting the current
that the input will draw from an exter
current through the transistor output to less than 50 mA. At 50 mA, the transistor will drop approximately 1.2V from

2.3.1.6 CONNECTING THE CONCENTRATION ALARM RELAY (OPTION 61)
The concentration alarm option provides four (4) “dry contact” relays on the rear panel (Figure 2-10) , each with 3 pins: Common (C), Normally Open (NO), and Normally Closed (NC). The Relays can be mapped to reflect various internal instrument conditions and states. ConFigure these outputs through the Setup>Digital Outputs menu (Section 2.5.7) under MB Relay [1 thru 4].
Figure 2-10. Concentration Alarm Relay
2.3.1.7 CONNECTING THE COMMUNICATION INTERFACES
For remote communications, the rear panel provides Ethernet, USB, RS-232, optional RS-232 Multidrop, and optional RS-485 connectors. In addition to using the appropriate
cables, each type of communication method must be configured using the SETUP>COMM menu, Section 2.5.10).
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 access port. Although Ethernet is DHCP-enabled by default, it should be manually configured (Section 2.5.10.5) with a static IP address.

RS-232 CONNECTION
IMPACT ON READINGS OR DATA
For RS-232 communications with data terminal equipment (DTE) or with data communication equipment (DCE) connect either a DB9-female-to-DB9-female cable (Teledyne API part number WR000077) or a DB9-female-to-DB25-male cable (Option 60A), as applicable, from the analyzer’s rear panel RS-232 port to the device. Adjust the rear panel DCE-DTE switch (Figure 2-2) to select DTE or DCE as appropriate.
Configuration: Section Section 3.2.1 and/or Section 3.4.2 (for Hessen protocol).
IMPORTANT
Cables that appear to be compatible because of matching connectors may incorporate internal wiring that makes the link inoperable. Check cables acquired from sources other than Teledyne API for pin assignments (Figure 2-11) before using.
RS-232 COM PORT CONNECTOR PIN-OUTS
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.

RS-232 MULTIDROP OPTION CONNECTION
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
When the RS-232 Multidrop option is installed, connection adjustments and configuration through the menu system are required. This Section provides instructions for adjusting the internal connections, then for making the 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.
Printed Circuit Assemblies (PCAs) are sensitive to electro­static discharges too small to be felt by the human nervous system. Failure to use ESD protection when working with electronic assemblies will void the instrument warranty. Refer to the manual, Fundamentals of ESD, PN 04786, which can be downloaded from our website at http://www.teledyne-api.com
under Help Center
> Product Manuals in the Special Manuals section.
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 2-13. 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 Pins 21 ↔ 22 as indicated in. (Do this for all but the last 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 (again refer to Figure 2-13):
J3 on the Multidrop/LVDS PCA to the CPU’s COM1 connector
(Note that the CPU’s COM2 connector is not used in Multidrop)
J4 on the Multidrop/LVDS PCA to J12 on the motherboard

Note If you are adding an instrument to the end of a previously
configured chain, remove the shunt between Pins 21
4. Close the instrument.
5. Referring to Figure 2-14 use straight-through DB9 male DB9 female cables to interconnect the host RS232 port to the first analyzer’s RS232 port; then from the first analyzer’s COM2 port to the second analyzer’s RS232 port; from the second analyzer’s COM2 port to the third analyzer’s RS232 port, etc., connecting in this fashion up to eight analyzers, subject to the distance limitations of the RS-232 standard.
6. On the rear panel of each analyzer, adjust the DCE DTE switch so that the green and the red LEDs (RX and TX) of the COM1 connector (labeled RS232) are both lit. (Ensure you are using the correct RS-232 cables internally wired specifically for RS­232 communication; see Error!

exposure to CO.
This Section provides not only pneumatic connection information, but also important information about the gases required for accurate calibration; Section 2.3.3 shows the pneumatic flow diagrams for the analyzer in its basic configuration and with options.
Before making the pneumatic connections, carefully note the following cautionary and special messages:
CAUTION – General Safety Hazard
Carbon monoxide (CO) is a toxic gas. Do not vent calibration gas or sample gas into enclosed areas.
Obtain a Safety Data Sheet (SDS) for this material. Read and rigorously follow the safety guidelines described there.
Sample and calibration gases should only come into contact with PTFE (Teflon), FEP, glass, stainless steel or brass.
The exhaust from the analyzer’s internal pump MUST be vented outside the shelter or immediate area surrounding the instrument.
It is important to conform to all safety requirements regarding

ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
LEAK CHECK
Maximum Pressure: Ideally the maximum pressure of any gas at the sample
inlet should equal ambient atmospheric pressure and should NEVER exceed
1.5 in-hg above ambient pressure.
Venting Pressurized Gas: In applications where any gas (span gas, zero air
supply, sample gas is) received from a pressurized manifold, a vent must be provided to equalize the gas with ambient atmospheric pressure before it enters the analyzer to ensure that the gases input do not exceed the maximum inlet pressure of the analyzer, as well as to prevent back diffusion and pressure effects. These vents should be:
• at least 0.2m long
• no more than 2m long
• vented outside the shelter or immediate area surrounding the instrument.
Dust Plugs: Remove dust plugs from rear panel exhaust and supply
line fittings before powering on/operating instrument. These plugs should be kept for reuse in the event of future storage or shipping to prevent debris from entering the pneumatics.
IMPORTANT
Run a leak check once the appropriate pneumatic connections have been made; check all pneumatic fittings for leaks using the procedures defined in Section 5.6.3.
See Figure 2-2 and Table 2-2 for the location and descriptions of the various pneumatic inlets/outlets referenced in this section.

2.3.2.1 IMPORTANT INFORMATION ABOUT CALIBRATION GASES
2614a
CO in Zero Air
45 ppm
Zero air and span gas are required for accurate calibration.
ZERO AIR
Zero air is 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, in this case CO and water vapor. If your analyzer is equipped with an Internal Zero Span (IZS) or an external zero air scrubber option, it is capable of creating zero air.
If the analyzer is NOT equipped with the optional CO2 sensor, zero air should be scrubbed of CO
as well, as this gas can also have an interfering effect on CO
2
measurements.
For analyzers without an IZS or external zero air scrubber option, a zero air generator such as the Teledyne API Model T701 can be used.
SPAN GAS
Span gas is 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 the case of CO measurements made with the T300 or T300M Analyzer, it is recommended that you use a span gas with a CO concentration equal to 80-90% of the measurement range for your application.
EXAMPLE: If the application is to measure between 0 ppm and 500 ppb, an appropriate span gas concentration would be 400-450 ppb CO in N2.
Cylinders of calibrated CO gas traceable to NIST-Standard Reference Material specifications (also referred to as SRMs or EPA protocol calibration gases) are commercially available. Table 2-6 lists specific NIST-SRM reference numbers for various concentrations of CO.

Some applications, such as EPA monitoring, require a multipoint calibration procedure where span gases of different concentrations are needed. We recommend using a bottle of calibrated CO gas of higher concentration in conjunction with a gas dilution calibrator such as a Teledyne API’s T700. This type of calibrator precisely mixes a high concentration gas with zero air (both supplied externally) to accurately produce span gas of the correct concentration. Linearity profiles can be automated with this model and run unattended over night.

Impact on Readings or Data

2.3.4 STARTUP, FUNCTIONAL CHECKS, AND INITIAL CALIBRATION

The analyzer’s cover must be installed to ensure that the temperatures of the GFC Wheel and absorption cell assemblies are properly controlled.
We recommend reading Section 6 to become familiar with the principles of operation.
When the instrument is first started (Section 2.3.4.1, check its functionality (Section 2.3.4.3) and run an initial calibration (Section 4). Section 2.4 introduces the menu system, and Section 2.5 provides setup/customization instructions.
2.3.4.1 STARTUP
Upon initial startup, a sequence of status screens (Figure 2-28) appear prior to the Home page (Figure 2-29).
54 Getting Started 083730300A DCN8101
Figure 2-28. Status Screens at Startup
Upon any startup, this instrument should warm up for approximately one hour before reliable measurements can be taken.
Page 57
Figure 2-29. Home Page Example
2.3.4.2 ALERTS: WARNINGS AND OTHER MESSAGES
Because internal temperatures and other conditions may be outside the specified limits during the analyzer’s warm-up period, the software will suppress most Alerts for 30 minutes after power up. The Alerts page (Figure 2-30) shows the status of any active warning conditions or user-configured Events. (Section 2.4.3 provides more detailed information about Alerts, and Section 2.5.2 addresses Events).
Alerts can be viewed and cleared via either the Alerts menu or the Alerts shortcut (Caution symbol, bottom right corner of the screen). Although these alerts can be cleared from the Active Alerts page, a history of all alerts remains in the Utilities>Alerts Log page.
Figure 2-30. Viewing Active Alerts Page
If Alerts about warning conditions persist after the warm up period or after being cleared, investigate their cause using the troubleshooting guidelines in Section 5.7.
083730300A DCN8101 Getting Started 55
Page 58
2.3.4.3 FUNCTIONAL CHECKS
After warm-up, verify that the software properly supports any hardware options that are installed (Setup>Instrument menu), and that the instrument is functioning within allowable operating parameters. Check the Dashboard page against the instrument’s Final Test and Validation Data sheet, which lists these values as they appeared before the instrument left the factory. (If any functional parameters are not displayed, conFigure the Dashboard through the Setup>Dashboard menu to add them; see Section 2.4.2).
These functions are also useful tools for diagnosing problems (information provided in Section 5.7.2).
2.3.4.4 INITIAL CALIBRATION
Before operation begins, the analyzer requires initial calibrations for the location in which it will perform any of the gas analyses. Also, any time an analyzer is moved or its configuration changed, it must be calibrated. The method for performing a calibration differs slightly depending on whether or not any of the available internal zero air or valve options are installed. Follow the appropriate calibration instructions in Section 4.

2.4.3 ALERTS

Alerts are notifications triggered by specific criteria having been met by either factory­defined conditions (standard and not editable) or user-defined Events (Section 2.5.2). The Active Alerts page shows the status of any active warning conditions or Events that have been triggered.
When Alerts are triggered, a caution symbol appears in both the Alerts menu tab and in the bottom right corner of the software interface, which serves as a shortcut to the Alerts page from any other page. View a list of currently active Alerts by pressing either the Alerts menu on the Home screen or by pressing the Alerts shortcut (Figure 2-35).
While Alerts can be cleared from the Active Alerts page, they remain recorded in the Utilities>Alerts Log menu.
Figure 2-35. Navigating to the Active Alerts Page
Alerts can be configured as either latching (appears in Active Alerts screen when Event is triggered and must be cleared by the user) or non-latching (Active Alerts screen continuously updates based on the Event criteria, clearing on its own). See Section 2.5.2.
To clear Alerts from the Active Alerts page, either check individual boxes to choose specific Alerts, or check the Select All box to choose all Alerts, then press the Clear Selected button.

CAUTION!
These instructions assume that the Current Loop Option is installed (Section 2.3.1.3).
This
option places circuitry in series with the output of the D-to-A converter on the
motherboard that changes the normal DC voltage output to a 0-20 milliamp signal.
Adjusting 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 series with the output circuit. See Figure 2-6 for pin assignments and diagram of the analog output connector.
Do not exceed 60 V peak voltage between current loop outputs
and instrument ground.
Figure 2-55. Setup for Checking / Calibration Current Output Signal Levels
An alternate method for measuring the output of the Current Loop converter is to connect a 250 ohm ±1% resistor across the current loop output in lieu of the current meter (see Figure 2-6 for pin assignments and diagram of the analog output connector). This allows the use of a voltmeter connected across the resistor to measure converter output as VDC or mVDC.

3 COMMUNICATIONS AND REMOTE OPERATION

This instrument’s rear panel connections can include an Ethernet port, a USB port (option) and two serial communications ports labeled RS232, which is the COM1 port in the software menu, and COM2 (refer to Figure 2-2). These ports allow the ability to communicate with, issue commands to, and receive data from the analyzer through an external computer system or terminal. Connection instructions were provided in Section 2.3.1.7. Configuration information was provided in Section 2.5.10.
This Section provides pertinent information regarding communication equipment, the communications ports, and communications protocol. Data acquisition is set up through the Datalogger (Section 2.5.1).
3.1 DATA TERMINAL/COMMUNICATION EQUIPMENT (DTE
DCE)
RS-232 was developed for allowing communications between data terminal equipment (DTE) and data communication equipment (DCE). Basic terminals always fall into the DTE category whereas modems are always considered DCE devices. The difference between the two 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.
To allow the analyzer to be used with terminals (DTE), modems (DCE) and computers (which can be either), a switch mounted below the serial ports on the rear panel, labeled DCE DTE (Figure 2-2), allows the user to set the RS-232 configuration for one of these two data devices. This switch exchanges the Receive and Transmit lines on RS-232 emulating a cross-over or null-modem cable. The switch has no effect on COM2.

3.2 MODES, BAUD RATE AND SERIAL COMMUNICATION

Referring to Table 2-18, use the SETUP>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 serial communications. The instrument’s baud rate and personal computer baud rate must match.

Page 86

3.2.1 SERIAL COMMUNICATION: RS-232

LED
FUNCTION
The RS232 and COM2 communications ports operate on the RS-232 protocol (default configuration). Configurations possible for these two ports are:
RS232 port can also be configured to operate in single or RS-232 Multidrop mode (Option
62); refer to Section 2.3.1.7.
COM2 port can be left in its default configuration for standard RS-232 operation including multidrop, or it can be reconfigured for half-duplex RS-485 operation (please contact the factory for this configuration).
Note
A code-activated switch (CAS), can also be used on either port to connect typically between 2 and 16 send/receive instruments (host computer(s) printers, data loggers, analyzers, monitors, calibrators, etc.) into one communications hub. Contact Teledyne API Sales (front cover, this manual) for more information on CAS systems.
When the rear panel COM2 port is in use, except for multidrop communication, the rear panel USB port cannot be used. (Alternatively, when the USB port is enabled, COM2 port cannot be used except for multidrop).
3.2.1.1

SERIAL COMMUNICATION: RS-485 (OPTION)

The COM2 port of the instrument’s rear panel is set up for RS-232 communication but can be reconfigured for RS-485 communication. Contact Technical Support for reconfiguration unless this option was elected at the time of purchase, then the rear panel was preconfigured at the factory.

3.3 ETHERNET

When using the Ethernet interface, 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 network to the analyzer using NumaView™ Remote, terminal emulators or other programs.
The Ethernet connector has two LEDs that are on the connector itself, indicating its current operating status.
amber (link) On when connection to the LAN is valid.
green (activity Flickers during any activity on the LAN.
Table 3-1. Ethernet Status Indicators
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; however, it should be configured with a Static IP address as soon as practical. See Section 2.5.10.5 for configuration details.

This Section is organized into subsections as follows:
SECTION 4.1 – Important Precalibration Information: contains important information you should know before calibrating the instrument.
SECTION 4.2 – Calibration Procedures: provides procedures for both calibration and calibration checks of basic and valve option configurations.
SECTION 4.3 – Automatic Zero/Span Cal/Check (Auto Cal): describes the procedure for using the AutoCal feature to check calibration or to calibrate the instrument. (The AutoCal feature requires that either the zero/span valve option or the internal span gas generator option be installed and operating).
SECTION 4.4 – CO Calibration Quality: describes how to evaluate the quality of each calibration.

4.1 IMPORTANT PRECALIBRATION INFORMATION

Note
A start-up period of 4­calibrating the analyzer.

4.1.1 CALIBRATION REQUIREMENTS

Calibration of the T300/T300M Analyzer requires specific 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 PTFE (Teflon), FEP, glass, stainless steel or brass
Optionally, a recording device such as a strip-chart recorder and/or data logger. (For
electronic documentation, the internal data acquisition system DAS can be used by configuring the Datalogger throught the Setup>Data Logging menu, Section 2.5.1).
Traceability Standards

Page 93

4.1.2 ZERO AIR

Zero air or zero calibration gas is defined as a gas that is similar in chemical composition to the measured medium but without the gas to be measured by the analyzer.
For the T300/T300M zero air should contain less than 25 ppb of CO and other major interfering gases such as CO and Water Vapor. It should have a dew point of -5°C or less.
If your application is not a measurement in ambient air, the zero calibration gas should be matched to the composition of the gas being measured.
Pure nitrogen (N2) can be used as a zero gas for applications where CO is measured in nitrogen.
If your analyzer is equipped with an external zero air scrubber option, it is capable of creating zero air from ambient air.
For analyzers without the zero air scrubber, a zero air generator such as the Teledyne API’s T701 can be used. Please visit the company website for more information.

4.1.3 CALIBRATION (SPAN) GAS

Span Gas is 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 and should be certified traceable to NIST Standard Reference Materiald (SRM). It is recommended that the span gas used have a concentration equal to 80-90% of the full measurement range.
If Span Gas is sourced directly from a calibrated, pressurized bottle, use the exact concentration value printed on the bottle.
For oxygen measurements using the optional O of 21% O
For quick checks, ambient air can be used at an assumed concentration of 20.8%.
Generally, O

4.1.4 INTERFERENTS

It should be noted that the gas filter correlation method for detecting CO is subject to interference from a number of other gases that absorb IR in a similar fashion to CO. Most notable of these are water vapor, CO
, N2O (nitrous oxide) and CH4 (methane). The
2
T300/T300M has been successfully tested for its ability to reject interference from of these sources, however high concentrations of these gases can interfere with the instrument’s ability to make low-level CO measurements.
For a more detailed discussion of this topic, see Section 6.1.2.4.

4.1.5 DILUTION RATIO OPTION SOFTWARE SET UP

If your application involves diluting the sample gas before it enters the analyzer, and the Dilution Ratio Option is enabled:
1. Set the appropriate units of measure (Setup>Vars>User Units).
2. Select the reporting range mode (Setup>Vars>Range Mode [Single or Dual]).
083730300A DCN8101 Calibration 91
Page 94
3. Set the reporting range (Setup>Analog Output>CO Concentration, Min Max). Ensure that the upper span limit entered for the reporting range (in the Max field) is the maximum expected concentration of the undiluted gas.
4. Set the dilution factor as a gain, e.g., a value of 20 means 20 parts diluent and 1 part sample gas (Setup>Vars>Dilution Factor).
5. Calibrate the analyzer; ensure 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 ppm and the dilution ratio of the sample gas is 20 gain, either:
a span gas with the concentration of 100 ppm can be used if the span gas
passes through the same dilution steps as the sample gas, or;
a 5 ppm span gas must be used if the span gas IS not routed through the
dilution system.

4.1.6 SECOND GAS SENSOR OPTIONS CALIBRATION

For the optional O2 sensor, calibrate per Section 4.6.1 during installation of the instrument.
For the optional CO
sensor, calibrate per Section 4.6.2 during installation of the
2
instrument.

4.1.7 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 T300/T300M.
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, make use of the internal data acquisition system (DAS) by setting up the Data Logger.

4.2 CALIBRATION PROCEDURES

Check that the pneumatic connections for the specific instrument configuration are as instructed in Section 2.3.2.
Verify/change (if needed) the settings as follows:
User Units (unit of Measure): PPB (Setup>Vars>User Conc Units)
Min and Max Concentration Range (Max should be highest concentration
expected to measure) (Setup>Analog Outputs>Analog Output[#], Signal Out, [Gas] Concentration)

2. Either check or calibrate as follows:
then press Stop.
b. Record the reading(s).
3. Press the Stop button and return to Home screen.
4. In the Dashboard, check and record the Slope(s) and the Offset(s). (See Table 4-4 in Section 4.4 for expected/acceptable values).
enter the CO concentration.
b. Verify the concentration reading is the
same as the CO concentration being supplied.
c. If correct, wait to reach stability, then
press the Span button.

4.2.2.1 USE OF ZERO/SPAN VALVE WITH REMOTE CONTACT CLOSURE
Contact closures for controlling calibration and calibration checks are located on the rear panel CONTROL IN connector. Instructions for setup and use of these contacts are in Section 2.3.1.5.
When the contacts are closed for at least 5 seconds, the instrument switches into zero, low span or high span mode and the internal zero/span valves will be automatically switched to the appropriate configuration.
The remote calibration contact closures may be activated in any order.
It is recommended that contact closures remain closed for at least 10 minutes to establish a
reliable reading.
The instrument will stay in the selected mode for as long as the contacts remain closed.
If contact closures are being used in conjunction with the analyzer’s AutoCal (see Section 4.3) feature and the AutoCal attribute “Calibrate” is enabled (selection box is checked), the analyzer will not recalibrate the analyzer UNTIL the contact is opened. At this point, the new calibration values will be recorded before the instrument returns to SAMPLE mode.
If the AutoCal attribute “Calibrate” is disabled (selection box is unchecked), the instrument will return to SAMPLE mode, leaving the instrument’s internal calibration variables unchanged.

4.3 AUTOMATIC ZERO/SPAN CAL/CHECK (AUTO CAL)

The Auto Cal feature allows unattended periodic operation of the ZERO/SPAN valve options by using the instrument’s internal time of day clock. Auto Cal operates by executing preprogrammed calibrations or calibration checks set up by the user to initiate the various calibration states of the analyzer and to open and close valves appropriately. It is possible to set up and run up to three separate preprogrammed calibrations or calibration checks (labeled # 1, 2 and 3). Each calibration or check can operate in one of three modes (Zero, Low or High), or be disabled.
Table 4-1 and Table 4-2 show how to set up the operating states of each calibration or check, and Table 4-3 shows how to program the execution of each.
