Carry out calibration on the 15-V range items first according to steps E to H. Then,
carry out calibration on the 150-V range items.
The shunt resistor is not used, but you can leave it connected.

1. Press the or
2. Connect a CC power supply to the load input terminal and supply 0.3 A.
Set the voltage of the power supply to 15.5 V or greater.
3. Press the ENTER key.
The load automatically turns on, and the offset calibration (CV 15 V Offset
Adjustment) screen appears.
