7. Troubleshooting
To aid the user in diagnosing the monitor, a diagnostic mode
can be used to display critical, low level parameters. Section
7.1 describes the operation of the Diagnostic Mode. Section
7.2 summarizes possible encountered problems and suggested
solutions. If the user turns the IAQRAE monitor on in
Diagnostic Mode and refers to the table in Section 7.2, the
problem can usually be narrowed down and corrected without
having to return the monitor for repair.
WARNING
The diagnostic mode allows the user to set several low level
parameters that are very critical to the operation of the monitor.
Extra care should be taken when setting these low level
parameters. If the user is not familiar with these parameters
and sets them incorrectly, it may cause the monitor to shut
down or malfunction. The diagnostic mode should be used by
qualified personnel only.
