4.3.5 System Self-Diagnostic Test

The Model 3000TA 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.
