7.1.2. FAULT DIAGNOSIS WITH TEST FUNCTIONS
Besides being useful as predictive diagnostic tools, the TEST functions, viewable from
the front panel, can be used to isolate and identify many operational problems when
combined with a thorough understanding of the analyzer’s theory of operation (Section
8). We recommend using the APICOM remote control pr
ogram to download, graph and
archive TEST data for analysis and long-term monitoring of diagnostic data ( Section
4.15.2.8).
The acceptab
le ranges for these test functions are listed in Appendix A-3. The actual
values for these test functions on checkout at the factory were also listed in the Final
Test and Validation Data Sheet, which was shipped with the instrument. Values outside
the acceptable ranges indicate a failure of one or more of the analyzer’s subsystems.
Functions with values that are within the acceptable range but have significantly
changed from the measurements recorded on the factory data sheet may also indicate a
failure or a maintenance item. A problem report worksheet has been provided in
Appendix C (Teledyne API part number 04503) to assist in recording the value of these
test functions. The following table contains some of the more common causes for these
values to be out of range.
