4.3.5 System Self-Diagnostic Test
The Model 3010MA has a built-in self-diagnostic testing routine.
Pre-programmed signals are sent through the power supply, output 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 3. (See System Self Diagnostic Test in Chapter 5
for number code.)
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.
