Error Messages
Table 3-3 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).
