Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

PSM Diagnostic Procedures

The Linear Power Supply board can be tested by checking the DCPS - TEST function on the front panel. It should read 2500 mV ± 200 mV. If the value is outside this range, individual output voltages can be tested on connector P3, see Schematic in the Appendix for pinouts.

The Switching Power Supply output can be tested by observing the temperature of the PMT cold block using the PMT TEMP - TEST function. The temperature should be constant –5 ± 2°C. The output voltage can be observed on J10 of the Switch Board. It should be 15 VDC ± 0.5.

The Switch Board can be tested by observing the diagnostic LEDS along the top edge of the board. The following Table 9-10 describes the typical operation of each LED.
