9.1.3.2 Electric Test

This function injects a constant voltage between the preamplifier and the buffer amplifier on the preamp board. Electric test checks part of the preamp, the V/F and computer for proper functioning. The result of electric test should be a smooth quiet signal as shown by constant values for the NO, NOx concentrations, the NO2 concentration should be near zero. Likewise the analog outputs should produce a smooth quiet trace on a strip chart.

Procedure:

1.Scroll the TEST function to PMT.

2.Press SETUP-MORE-DIAG, then scroll to ELECT TEST by pressing the NEXT button. When ET appears, press ENTR to turn it on.

3.The value in PMT should come up to 2000 mV ± 500 mV in less than 15 sec.

If the HVPS or the span gain adjust on the preamp card has been changed without doing the FACTORY CALIBRATION procedure, the reading in step 3 may be different than 2000 mV, since the overall calibration affects ELECTRIC TEST. See Section 9.1.6 for factory calibration procedure.
