Error Messages
Table B-3 lists and describes messages that are generated by the Counter during
Self-Test or during operation to indicate that a problem has been detected. These
messages are displayed on the Counter’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
RS-232).
