4.3.5 System Self-Diagnostic Test

The Model 2010A has a built-in self-diagnostic testing routine. Pre-
programmed signals are sent through the power supply, output board, preamp
board and sensor circuit. The return signal is analyzed, and at the end of the test
the status of each function is displayed on the screen, either as OK or as a
number between 1 and 1024. (See System Self Diagnostic Test in chapter 5
for number code.) If any of the functions fails, the System Alarm is tripped.
Note: The sensor will always show failed unless identical gas is
present in both channels at the time of the SELF-TEST.
The self diagnostics are run automatically by the analyzer whenever the
instrument is turned on, but the test can also be run by the operator at will. To
initiate a self diagnostic test during operation:
Press the System button to start the System function.
Contrast Function is DISABLED
(Refer to Section 1.6)
Use the < > arrow keys to blink MORE, then press Enter.
Use the < > arrow keys again to move the blinking to the SELF–TEST
and press Enter. The screen will follow the running of the diagnostic.
