4.12 Voltage and Current Monitor
To monitor the output voltage and output current, use the monitor output terminal (MONITOR OUT) on
the front panel. For the connection, use a coaxial cable with a BNC connector. To monitor the output
voltage, perform connection to the Vo terminal, and to monitor the output current, perform connection
to the Io terminal.
The specifications of the monitor output terminal are as follows.
