Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
2 OPERATION
2.1 Key Features
The important features of the Teledyne API Model 300M CO Analyzer are listed below.
2.1.1 CO Readout
The Teledyne API Model 300M CO Analyzer constantly displays the current Carbon Monoxide reading (in PPM) in the upper right hand corner of the alphanumeric display.
2.1.2 CO Analog Output
The Teledyne API CO Analyzer provides a buffered analog output of the current CO readings on each of two pairs of outputs on the rear panel (see Figure
2.1.3 E2ROM Backup Of Software Configuration
The Teledyne API CO Analyzer has a few jumpers that need to be set by the operator. Configuration of the analyzer is done under software control and the configuration options are stored in electrically erasable (E2) ROM. Thus, configuration options are saved even when the analyzer is powered off.
There is one exception to this. The analog output voltage ranges are set by jumpers on the A/D- I/O board as shown in Section 10.6.3.
2.1.4 Adaptive Filter
The M300M CO Analyzer is able to provide a smooth, stable output by means of an adaptive filter. During conditions of constant or nearly constant concentration the filter is allowed to grow to 200 samples (1 minute) in length, providing a smooth, stable reading. If a rapid change in concentration is detected, the filter is cut to 20 samples to allow the analyzer to quickly respond to rapidly varying signals.
