How to Operate
1. Before operating the unit, check that the input and output are properly connected as shown in
[1-4 How to Ground]. For safety, be sure to connect the ground terminal on the rear panel to the
ground at one point.
2. Plug the end of the enclosed AC input cord to the AC input connector on the rear panel and then
plug another end to an electric outlet.
For safety, be sure to fix the cord with a plastic clamp for securing cables.)
3. Connect the interlock. Refer to [3-3 e. Interlock].
4. Turn on the POWER Switch. The unit will be in stand-by mode.
In this mode, no high-voltage has been applied to the output terminal.
5. When the HV ON/OFF switch is turned on, the HV lamp will be on in red, the unit will turn on its
output. (In the case of local mode)
6. Turn the output voltage setting dial to set your desired value.
7. When you want to lock the output at a set voltage, turn the locking lever
clockwise as shown in the diagram to the left
8. The output voltage and current are displayed on the front panel digital
meter.
9. When the output polarity switching switch is set to
“NEG”, the output polarity will be negative and
set to
“POS” be positive. When it is set to “0”, the output voltage will be “0”.
10. In order to end the operation, set the setting dial for the output voltage to
“0” or leave it when the
same value is used again, turn off the HV ON/OFF switch and POWER ON/OFF switch in order.

Other Function
a. Overvoltage protection (O.V.P)
This unit has overvoltage protection. In case of an abnormal state, the unit will limits the output
voltage at approx. 110% of the maximum rated voltage to protect the unit and the load.
b. Overcurrent protection (O.C.P)
This unit has overcurrent protection. In case of an overcurrent state, the unit droops the otuput
voltage to limit its output current.
