PAS SERIES Maintenance 7-15
■ Output current offset and full scale
6. Press the CURRENT
switch to display "OF 0" on the cur-
rent display.
7. Turn on the OUTPUT.
Approximately 10 % of the rated output current is output.
8. Turn the dial so that the DVM reading is equal to 10 % of the
rated output current.
Turning the dial while pressing the SHIFT switch increases the
variable width.
9. Turn off the OUTPUT.
The current display shows "OF 1."
10.Press the CURRENT switch to display "FS 1" on the cur-
rent display.
11. Turn on the OUTPUT.
Approximately 100 % of the rated output current is output.
12.Turn the dial so that the DVM reading is equal to the rated
output current.
Turning the dial while pressing the SHIFT switch increases the
variable width.
13.Turn off the OUTPUT.
The current display shows "FS 3."
14.Press the SET switch to store the calibration value.
The current display returns to "FS 0."
You are done calibrating the output current.
If you wish to exit from the output current calibration here, turn off
the PO
WER switch.
OCP (overcurrent protection) calibration procedure
Be sure to complete the calibration of the current system before per-
forming OCP calibration.
1. Turn off the POWER switch.
2. Connect a shunt resistor and a DVM to the output terminal.
Shown in Fig.7-16.
