8-8 Maintenance and Calibration
Carry out calibration on the low range items first according to steps A to D. Then,
carry out calibrations for Mid range and High range.

■ Low range calibration
Step A: Calibration of the offsets of internal reference voltage for out-
put setting and measured value
1. Connect a shunt resistor that matches the value corresponding to 10 %
of the low range full scale.
2. Press the or
(Low)".
3. Connect a CV power supply to the load input terminal and apply 5 V.
Set the current of the power supply approximately in the range of 2 % to
5 % of the rated current of the load device.
4. Press the ENTER key.
The load automatically turns on, and the offset calibration (CC (Low) Offset
Adjustment) screen appears.
