3.3.4 System Self-Diagnostic Test
The Model 6000A 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.
