Offset/Full Scale Calibration of Output Voltage Settings
1. Disconnect the load wires and the remote sensing
wires. Connect the digital multimeter to the output
terminal.
Turn the POWER switch ON and OUTPUT OFF in
advance.

2. Set the constant voltage setting value to [ xV ]
and the constant current setting value to [ yA ] and
set the output to ON.

On how to set, see Operating as Constant Voltage
Power Supply under Basic Operations. (page27)
3. Press the FUNC. key.
4.
Turn the VOLTAGE dial to display the setting item
number 20 in the Number Display (voltage).
* At that time, turn off the Number Display (current).
5. Adjust so that the output voltage becomes [ xV ]
with the CURRENT dial.

6. Press the FUNC. key to settle the offset calibration
value of the output voltage settings.
