lists and describes messages that are generated by the instrument
during Self-Test or during operation to indicate that a problem has been
detected. These messages are displayed on the instrument’s front-panel display
and are also sent via the RS-232 serial output (note that, in many cases, the exact
message text that is displayed on the front panel is a condensed form of the
message that is sent via the RS-232 interface).
