4.3.5 System Self-Diagnostic Test
The Model 3000ZA2G 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
