You can also set the number of periods as criteria for the duration of an AC test.
The
test duration is adjusted based on a test frequency of 0.1 Hz.
For test capacitances
above >0.5 µF, the time is automatically adjusted at the beginning of an AC test.

by a defined time period
or by a defined amount of peri
ods is distinguishable via the profile view in the main
