7.2 Using the Built-In-Self Test (BIST) fault
diagnostics
The analyzer has a Built-In-Self-Test (BIST) function that can be used to perform failure
diagnosis of some functions other than a complete failure of the equipment. The BIST is
accessed and controlled through the display controller mounted on the front panel of the
analyzer. The BIST runs in the background when the analyzer is operating and continuously
monitors the analyzer for faults.
If the BIST detects a fault the STATUS display in the bottom left-hand corner of the Main
Screen ( Faults screen selection ) will change from OK to a flashing .
Analysis of the fault detected can be performed using the indicated Fault menu screen or
the Diagnostics menu screen .
7.2.1 Fault menu
The BIST function can be used to perform failure diagnosis of some functions in situations
where there is a fault other than a complete failure of the equipment. The BIST is accessed
and controlled through the
FAULTS screen accessed from the Main Menu screen mounted
on the front panel. This gives the operator access to any assess any Faults that the analyzer
has detected in the systems being monitored.
