4.3.5 System Self-Diagnostic Test
The Model BDS 3000 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.
