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 Analyzer showing all the major components.

Figure 9.1 is an electrical diagram of Model 300 CO Analyzer.

9.1 Power supply board adjustment

The power supply board provides +/-15v +12v and +5v DC power to the Analyzer. Four temperature linearization circuits, for the Analyzer main lamp, Sample temp, Box temp, and IZS carbon monoxide generator are also located on the power supply board.

Each circuit is a whetstone bridge with the measuring thermistor being one leg. A feedback circuit performs the required linearization. Zero adjust pots have been factory set and no field adjustment should be required.

9.1.1 Box temperature limits

The box temperature is measured by a thermistor located on the motherboard. The box temp is not controlled in the Model 300. The temperature is measured and displayed as a TEST function on the front panel (see Section 5.1). The alarm limits can be set via an RS-232 port command.
