3.3.4 System Self-Diagnostic Test

The Model 6600 has a built-in self-diagnostic testing routine. Pre-pro- grammed 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.)

Note: The sensor will always show failed unless Zero fluid is present in the sampling cell at the time of the SELF-TESTinput thru the sample inlet.

If any of the functions fails, the System Alarm is tripped, but is not tripped at the startup because it might give false alarm after a power failure.
