Page 9 - Principle of operation
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...

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...
Page 37 - PERFORMANCE TESTING
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 ...
Page 45 - Setup mode operation
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, ...

Page 59 - Test measurements; Diagnostic tests
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 ...
Page 65 - HANDLING WARNINGS
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...
Page 74 - Viewing and modifying variables
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...
