By inputting the output from the CLP-10 Clamp-on AC Pickup to the PS-100, variations in the drive current, from the start of ignition (IGN) charging to discharge, and from the start to end of injection (INJ), can be converted into a 0-5V pulse signal.

The trigger level for the 4-channel input can be set for each of the channels 1, 2, and the channels 3, 4.
The trigger level is switched between 4 steps.
