PAS SERIES Maintenance 7-13
13.Turn off the OUTPUT.
The voltage display shows "FS 3."
14.Press the SET
switch to store the calibration value.
The voltage display returns to "FS 0."
You are done calibrating the output voltage.
If you wish to exit from the output voltage calibration here, turn off
the PO

OVP (overvoltage protection) calibration procedure
Be sure to complete the calibration of the voltage system before per-
forming OVP calibration.
1. Turn off the POWER switch.
2. Connect a DVM to the output terminal.

3. Turn on the POWER switch while pressing the SET switch.
4. Chec
k that the current display shows "CAL."
If it is not, press the VOLTAGE switch.
5. Warm up the equipment including the DVM for sufficient
time.

6. Press the OVP s
witch to display "OVP" on the current display.
7. Press the VOLTAGE switch to display "OF 0" on the voltage
display.
8. Turn on the OUTPUT.
Calibration starts automatically (ON blinks) and the POWER
switch turns off. (This takes 30 s to 60 s.)
9. Turn on the POWER switch while pressing the SET switch.
10.Check that the current display shows "CAL."
If it is not, press the VOLTAGE switch.
11. Press the OVP switch to display "OVP" on the current display.
12.Press the VOLTAGE switch to display "FS 0" on the voltage
display.
13.Turn on the OUTPUT.
Calibration starts automatically (ON blinks) and the POWER
switch turns off. (This takes 30 s to 60 s.)
