FAULT DIAGNOSIS WITH DASHBOARD FUNCTIONS
In addition to being useful as predictive diagnostic tools, the functions viewable in the
Dashboard can be used to isolate and identify many operational problems.
The acceptable ranges for these functions are listed in the “Nominal Range” column of
the analyzer
Final Test and Validation Data Sheet
shipped with the instrument. Values
outside these acceptable ranges Indicates a failure of one or more of the analyzer’s
subsystems. Functions whose values are still within acceptable ranges but have
significantly changed from the measurement recorded on the factory data sheet may also
Indicates a failure.
Make note of these values for reference in troubleshooting.
USING THE DIAGNOSTIC SIGNAL I/O FUNCTIONS
The signal I/O functions in the Utilities>Diagnostics menu allows access to the digital
and analog I/O in the analyzer. Some of the digital signals can be controlled through the
Setup menu. These signals are useful for troubleshooting in three ways:
