Capture Conditions in Inrush Current Mode
Reminder:
Captures depend on the trigger event and a stop event. If the capture
ends with a stop event or if the recording memory of the PowerPad
®
is full, the
capture stops automatically.
The stop threshold for capture is calculated as follows:
[Stop threshold [A]] = [Start threshold [A]] × (100 – [Stop hysteresis [%]]) ÷ 100
Here are the conditions for triggering and stopping capture:
Triggering
filter type
Start and end conditions
A1
Start condition
ó
[A1 half-period RMS value] > [Start threshold]
Stop condition
ó
[A1 half-period RMS value] < [Stop threshold]
A2
Start condition
ó
[A2 half-period RMS value] > [Start threshold]
Stop condition
ó
[A2 half-period RMS value] < [Stop threshold]
A3
Start condition
ó
[A3 half-period RMS value] > [Start threshold]
Stop condition
ó
[A3 half-period RMS value] < [Stop threshold]
3A
Start condition
ó
[the half-period RMS value of
one
current channel]
> [Start threshold]
Stop condition
ó
[the half-period RMS values of
all
current channels]
< [Stop threshold]
