t analysis
To configure and run an I²t analysis:

Press
[Analyze] > Analysis > I²t
.

Press
Current Source

select the current measurement range and vertical resolution.
4.
Press
Inrush Trigger
and specify the current level at which the analysis will begin. You may
want to set this close to the expected peak to avoid falsely triggering on a small transient of
current. You can always move the first cursor to the left after running the test, if necessary.
5.
Press
Acq Time
and specify the duration of the analysis. It is better to set this a bit too long,
rather than too short.
6.
Press
Start
and follow the on-screen instructions. These instructions will tell you to turn off
the power supply, press
Next
, turn on the power supply, and press
Next
again. The screen
will display the result, using a default distance between the cursors as shown below.
