For the
Alarm
trigger type: The scan sweep is triggered by an alarm that has
tripped. To do this, select the Alarm trigger type in the test setup and assign a
channel to be a trigger. When the scan is started, the Product automatically starts
to monitor the channel set as the trigger for a tripped alarm. Once an alarm is
tripped, the scan sweep starts and runs as directed by the test setup. Scan sweeps
will continue as long as the alarm is tripped. If the alarm is no longer tripped, the
Product will finish the scan in progress then wait for next alarm trip.

View Scan Data and Statistics
The Scan Data feature lets the user see the scan data from the last scan sweep (see
Figure 4-4). This feature is located in the Scan menu (push
then push
). The
data on this menu updates in real-time. From the Scan Data menu, the user can open a
Statistics menu to view minimum, maximum, average, and standard deviation statistics
for each channel (see Table 4-4).
If Mx+B is applied to the channel, an [Mx+B] icon will show next to the channel
number. If an alarm is tripped, the alarm number will show next to the channel as a red
icon and also the measurement value will be red. See Figure 4-4.
