Scanning on Alarm In this configuration, the instrument sweeps the
scan list once each time a reading crossing an alarm limit on a channel.
You can also assign alarms to channels on the multifunction module.
For example, you can generate an alarm when a specific bit pattern
is detected or when a specific count is reached.
Note: For complete details on configuring and using alarms, refer to
“Alarm Limits” starting on page 122.
• 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. The monitored channel can be part of the scan
list but you can also use a channel on the multifunction module
(which does not have to be part of the scan list and you do not have to
use the Monitor function). For example, you can generate an alarm
on a totalizer channel which will initiate a scan when a specific count
is reached.
• You can specify a scan count which sets the number of alarms that
will be allowed before terminating the scan. See “Scan Count”
on page 86 for more information.
• All readings from the scan are stored in non-volatile memory.
Readings accumulate in memory until the scan is terminated
(until the scan count is reached or until you abort the scan).
• Mx+B scaling and alarm limits are applied to measurements during
the scan and all data is stored in non-volatile memory.
• Front-Panel Operation:
