Function of Terminals on the Rear Panel

External Trigger Function

If you select the trigger signal over the digital I/O interface on the rear panel of the

load, first select "DIGIO" to be the trigger source of the load. For details, refer to

descriptions in "Trigger Operation".

Current/Voltage Monitoring Function

The load provides voltage monitoring output connector (Vmon OUT) and current

monitoring output connector (Imon OUT) on the rear panel of the load. A 0-to-10 V

voltage output signal at the connector indicates the zero-to-full scale input current or

voltage. The input voltage and current are directly proportional to the output

voltage.

The current/voltage monitoring function enables you to use the external DVM or

oscilloscope to monitor the input current/voltage.
