Displayed error and status messages
During operation and programming, front-panel messages may be briefly displayed. Typical
messages are either status or error notifications (refer to the Error summary list (on page 8-3
) for a
complete list of these messages and their meanings).
Status and error messages are held in a queue. For information about retrieving messages from
queues, refer to Queues (on page E-2). For information about error messages, refer to the
Troubleshooting guide (on page 8-1).
Range
The selected measurement range affects the accuracy of the measurements and the maximum signal
that can be measured. If the range is changed, the display may contain dashes instead of a reading
(for example, --.---- mA). This indicates that no measurement was taken using the range that is
presently selected. To update the displayed reading, trigger a measurement (if in local control, press
the TRIG key).
