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.
