Calibration procedure of the output current control using
external voltage (CAL.7)
Fig. 8 -11 Connection for CAL.7
1
T u rn the POWER s w itch off.
2
Connect the voltage so u rce (Vref) to pins 19 and 20 of the J1
connector.
3
While holding do w n the SET key, t u rn on the POWER s w itch.
Keep holding the SET key until the ammeter is showing “CAL.1,” and the voltmeter is
showing 5 % of the rated voltage value. Warm up the PAT for at least 30 minutes.

Press the STORE key.
The ammeter shows “CAL.7,” and the voltmeter shows “10.00.”
8
Set Vref to 10.00 V.
9
Press the RECALL A (SHIFT+SET) key.
The calibration of the high end of the EXT CC CONT is set, and the EXT LED
