    Infra Red (IR) radiation by CO molecules at wavelengths near 4.5 microns. As illustrated in Figure 1-1, the Model 300M uses a high energy heated element to generate broad- band IR light. This light is passed through a rotating Gas Filter Wheel causing the beam to alternately pass through a gas cell filled with Nitrogen, (the Measure Cell) and a cell filled with CO/Nitrogen Mixture (the Reference Cell).

  • Page 37: Performance Testing

    3 PERFORMANCE TESTING Zero/span checking and calibration of the Teledyne API CO Analyzer is divided into two sections. Chapter 3 discusses the different methods by which the analyzer's zero and span settings may be checked and adjusted. The emphasis in Chapter 3 is on the operation of the buttons and the internal adjustments they make in the instrument.

  • Page 38: Span Check

    Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A 3.1.2 Span Check Allow the analyzer to sample span gas through the sample port. Press CAL button. After a few minutes the CO reading should be at the expected concentration. If the correct concentration is not reached, then the instrument can be adjusted to read the correct value.

  • Page 39: Dual Range Calibration

    3.1.3 Dual Range Calibration If the analyzer is being operated in Dual Range mode or Auto-Ranging mode, then the High and Low ranges must be independently calibrated. When the analyzer is in Dual or Auto Range mode you will be prompted to enter the range to calibrate whenever you enter a calibration command from the front panel.

  • Page 40: Span Valve (Option)

    3.2 Span Valve (Option) If the span valve option is installed and a source of CO span gas from the cylinder (20-25 PSIG) has been connected, the operator can check the span setpoint of the analyzer at any time by pressing the CALS button.

    Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A 3.4 Automatic Zero/Span Check Automatic zero/span checking (Z/S check) must be enabled in the setup mode. The Teledyne API Model 300M Carbon Monoxide Analyzer with Zero/Span Valves option offers capability to check the zero and span point automatically on a timed basis, or through remote RS-232 operation (see Section 3.7).

  • Page 47: Setup Mode

    4 SETUP MODE This section describes the setup variables that are used to configure the analyzer. 4.1 Setup Mode Operation ALL the setup variables are stored in the analyzer's EEPROM and are retained during power off and generally when new software revisions are installed. If a variable is modified, but ENTR is not pressed, the variable will not be changed and the analyzer will beep when EXIT is pressed.

    4. The concentration value is linearized over the range of 0 to 20,000 PPM by a multi-point software look-up table and corrected for temperature and pressure. 5. An average of the last 200 samples is computed and converted to the number displayed on the front panel.

  • Page 49: Setting The Co Concentration Range

    4.6 Setting the CO Concentration Range The CO concentration range is the concentration value that corresponds to the maximum voltage output at the rear panel (usually 5 volts). The M300M can operate in one of three analog output Range Modes. The Range Mode can be changed through the SETUP-RNGE-MODE menu. The modes are described below.

  • Page 50: Setting The Analog Output Offset

    4.7 Setting the Analog Output Offset In order to permit the analyzer to connect to a wider variety of strip chart recorders and other instruments, the analog output of the Carbon Monoxide readings can be adjusted by up to ±500 mV for 0-5 V range (or ±10% of current analog output range) in software. The default output offset is 0 mV.

  • Page 51: Data Acquisition System (Das)

    The Data Channels can be programmed and customized from the front panel. A set of default Data Channels has been included in the Model 300M software. These are described Section 4.11.1. For more information on programming custom Data Channels, a supplementary document containing this information can be requested from Teledyne API.

    The function of each of the default Data Channels is described below: Samples Carbon Monoxide concentration (Low Range) at one minute intervals CONC: and stores an average every hour with a time and date stamp. Readings during calibration and calibration hold off are not included in the data. The last 800 hourly averages are stored.

    Viewing these test measurements does not interfere with the operation of the Model 300M or the Carbon Monoxide reading in any way, so they may be viewed freely. If the value of any test function is displayed as “XXXX”, this indicates that the reading is off scale or otherwise non-valid.

  • Page 58: Diagnostic Tests

    5.2 Diagnostic Tests The diagnostic tests are used to help diagnose a problem in the analyzer and should only be used by skilled maintenance people since they can potentially interfere with the Carbon Monoxide reading. Table 5-1 lists low level diagnostic tests. To get into the diagnostic test mode, press SETUP-MORE-DIAG.

    5.3 M300M Internal Variables The M300M software contains many adjustable parameters. Many of the parameters are set at time of manufacture and do not need to be adjusted for the lifetime of the instrument. It is possible to change these variables either through the RS-232 port or the front panel. Altering the values of many of the variables, especially those not listed on Table 5-3, will adversely affect the performance of the instrument.

    Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A 7.6 Viewing and Modifying Variables The most powerful feature of the RS-232 interface is the ability of a host computer to view and modify the analyzer's internal variables. Just as the operator modifies the variables by means of the setup mode, the host computer modifies them by means of the RS-232 interface.
  • Page 78 After changing the variable's value, the CPU will respond with: V VARIABLE=VALUE WARNLO WARNHI [DATALO-DATAHI] <CRLF> which should reflect the new value. The values in square brackets are not required for all variables. If needed, the values are included on the command line, separated by spaces.
