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
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
Troubleshooting guide

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).
