Trigger settings can be used to search measurement data.
Locations that match the set trigger criteria in the measurement data are searched for and displayed
sequentially.
Using the same method to set triggers, it is possible to search for criteria different to those at the
time of measurement.
Example 1: The measurement trigger criteria is trigger level 0 V and the data search condition is
level 100 V.
Example 2: After measurement with a free run without a trigger, locations that exceed 100 V are
searched for.

will be defined according to the
start block and the number of
blocks to be measured.
