– In this scan configuration, you may use the Monitor function to continuously
take readings on a selected channel and wait for an alarm on that channel.
Channels do not have to be part of an active scan list to be monitored;
however, the channel must be configured for a measurement in order to be
monitored.
– All readings from the scan are stored in volatile memory. Readings accumulate
in memory until the scan is terminated (until the trigger count is reached or
until you abort the scan).
– You can specify a trigger count which sets the number of front-panel key
presses or scan trigger commands that will be accepted before terminating the
scan. See
on page 157 for more information.
– Mx+B scaling and alarm limits are applied to measurements during a manual
scanning operation and all data is stored in volatile memory.
Front Panel Operation:
Scan (Configure) > ALARM
To enable the Monitor function, select the desired channel and then press the
DMM or Channel (Measure) key. To initiate the scan, press the Scan (Measure)
key. When an alarm occurs, the scan starts and readings are stored in memory.
Note:
To stop a scan, press and hold the Scan (Measure) key.
You can also configure whether the instrument sweeps through the scan list one
time or continuously when an alarm condition is detected:
Scan (Configure) > ALARM > ALARM TRIG MODE > SINGLE|CONTIN
Remote Interface Operation:
The following program segment configures the
instrument to continuously scan when an alarm is detected.
