Offset/Full-Scale Calibration of Output Current Settings
1. Perform load with only the shunt resistor.
Disconnect the load wires and the remote sensing
wires.
Connect the shunt to the output terminal. Connect
the digital multimeter to the terminal located on the
shunt.
Turn the POWER switch ON and OUTPUT OFF in
advance.

Note:
Large current flows
through the wiring
material.
Use wires which will
not produce a voltage
drop below 0.8V.

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

3. Press the FUNC. key.
4.
Turn the VOLTAGE dial to display the setting
item number 22 in the Number Display (voltage).
* At that time, turn off the Number Display (current).
5. Adjust so that the output current becomes [ yA ]
with the CURRENT dial.
