Diagnostic Messages
The instrument performs background tests to verify data and
memory integrity. If there is a malfunction, a diagnostic message will
be shown on the diagnostics display. In the case of more than one
simultaneous malfunction, the diagnostic messages will be shown in
sequence, with the highest priority message being shown first. See
the section
Backgroud Tests and Diagnostic Messages
for a list of
the Diagnostic Messages and how to correct the problems that they
indicate.
