3.3.4System Self-Diagnostic Test

The Model 5000BF 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 4 for number code.) If any of the functions fails, the System Alarm is tripped.

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

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.

Testing Preamp — Cell

When the testing is complete, the results are displayed.

Power: OK Analog: OK

Cell: 2 Preamp: 3

The module is functioning properly if it is followed by OK. A number indicates a problem in a specific area of the instrument. Refer to Chapter 5 Maintenance and Troubleshooting for number-code information. The results screen alternates for a time with:

Press Any Key

Then the analyzer returns to the initial System screen.
