4.3.5 System Self-Diagnostic Test
The Model 3010PA 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.)
Note: Remote Probe connector must be connected to the Analysis
Unit, or sensor circuit will not be properly checked.
