Sensor Conditions in Ringing Current Mode

Reminder: Sensors depend on the trigger event and a stop event. If the capture
ends with a stop event or if the save memory of the PowerPad
stops automatically.
The stop threshold for capture is calculated as follows:
[End threshold [A]] = [Start threshold [A]] × (100 – [End hysteresis [%]]) ÷ 100
Here are the conditions for triggering and stopping capture:
