1.3 Principle of operation The detection and measurement of carbon monoxide in the Model 300 is based on the absorption of Infra Red (IR) radiation by CO molecules at wave lengths near 4.7 microns. In practice, the Model 300 uses a high energy heated element to generate broad-band IR light. This lig...
1.5 Installation and overview The Model 300 is shipped with the following standard equipment: 1. Power cord. 2. Instruction manual. CAUTION To avoid personal injury, always use two persons to lift and carry the Model 300. Upon receiving the Model 300 please do the following: 1. Verify no apparent sh...

1.7 Operation verification The Model 300 Analyzer is now ready for operation. 1. Read Sections 1.3 and all of Section 4 of the manual to understand the Analyzer operation. 2. Turn on the power by pressing the on/off switch on the front panel (see Figure 2.1). The display should turn on and green (sa...
2.0 OPERATION 2.1 Key features The important features of the Teledyne API Model 300 CO Analyzer are listed below. 2.1.1 CO readout The Teledyne API Model 300 CO Analyzer constantly displays the current Carbon Monoxide reading (in PPM) in the upper right hand corner of the alphanumeric display. 2.1.2...
3.0 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 ...
4.0 SETUP MODE This section describes the setup variables which 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 even when new software revisions are installed. NOTE IF A VARIABLE IS MODIFIE...
3. Slope and offset corrections are made to the CO concentration according to the equation: CORRECTED CONCENTRATION = SLOPE x MEASURED CONCENTRATION + OFFSET 4. The concentration value is linearized over the range of 0 to 1000 ppm by a multi-point software look-up table and corrected for temperature...
If the clock speed adjust variable has already been set to a value other than 0 and the speed is still too fast or too slow, ADD the required adjustment to the current value of the variable. For example if the clock speed adjustment is already set to +10 and the clock is 5 seconds too slow per day, ...
NEXT until D/A CALIBRATION is displayed and press ENTR. Press CFG to enter the D/A configuration menu. Use the NEXT and PREV buttons to select the desired analog output and press SET . Enter a value of from -500 mV to +500 mV (other ranges will ratio accordingly), followed by ENTR to accept the chan...
5.0 DIAGNOSTICS The Teledyne API carbon monoxide analyzer contains two levels of diagnostics: test measurements which can be viewed at all times (except when in setup) by pressing TEST , and lower level diagnostic operations which can only be performed by pressing SETUP-DIAG . 5.1 Test measurements ...
6.0 HANDLING WARNINGS When a system warning occurs, a warning message is displayed and the FAULT LED blinks. A warning indicates that something in the system needs to be checked or adjusted. Failure by the operator to respond to a warning may result in poor system performance and/or less accurate da...
7.5 Test measurements All the test measurements which can be displayed by pressing the TEST button are also available to the host computer via the RS-232 interface. The host computer should issue a request for a test measurement, and then the CPU will send the current value of the test measurement t...
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...
9.0 ADJUSTMENTS NOTE THE OPERATIONS OUTLINED IN THIS CHAPTER ARE TO BE PERFORMED BY QUALIFIED MAINTENANCE PERSONNEL ONLY! All adjustments to the Model 300 are easy to make. Pots and test points are readily accessible without removing any components. Figure 1.6 is a plan view of the Model 300 CO Anal...
9.2 A/D - D/A Calibration procedure Due to the stability of modern electronics, this procedure should not have to be performed more than once a year or whenever a major sub-assembly is exchanged or whenever analog output voltage range is changed . To calibrate the ADC, do the following: 1. Press SET...
To view the current dark offset, press SETUP-MORE-DARK-VIEW. Press EXIT when finished. No password is required to view the dark offset, only to change it. 9.4 Output voltage range changes Output voltage ranges are set by DIP Switch settings on the V/F board. To change the range for the analog output...
9.5 Flow readout adjustment The sensor module in the M300 consists of a flow sensor and a pressure sensor. See Figure 9.2 for a diagram of this module. From these three sensors two values are displayed on the front panel TEST function area. These are: • Sample flow • Sample cell pressure In order to...
10.0 TROUBLESHOOTING NOTE THE OPERATIONS OUTLINED IN THIS CHAPTER ARE TO BE PERFORMED BY QUALIFIED MAINTENANCE PERSONNEL ONLY! CAUTION DO NOT DISCONNECT CPU OR OTHER DIGITAL CARDS WHILE UNDER POWER. 10.1 Overview The Model 300 has been designed to rapidly detect possible problems and allow their qui...
absence of these actions will usually indicate either a CPU or Display failure. To determine which module is defective, perform the following procedure: 1. Turn off power. 2. Remove the ribbon cable from the CPU board to the Display; 3. Turn Power on. 4. A cursor character should appear in the upper...
10.4 Troubleshooting using test function values The Model 300 provides the capability to display, on operator demand, the values of Test Functions which allow the observation of key analyzer operating parameters. These Test Functions can be accessed by depressing the TEST Button on the instrument's ...
