Ammeter Offset/Full-Scale Calibration
Note: Before performing this operation, be sure to perform Offset/Full-scale Calibration (page172) of output current setting.
1. Perform load with only the shunt resistor.
Disconnect the load wires and the remote sensing
wires.
Connect the shunt (0.1 class) 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 26 in the Number Display (voltage).
* At that time, the current measured value is displayed
in the Number Display (current).
* The figure above is an example of connecting (HX-S-030-200G2)
5. Adjust the CURRENT dial so that the current
measured value displayed in the Number Display
(current) is the same as the actual output current value
(digital multimeter measurement).
* The figure above is an example of connecting (HX-S-030-
200G2)
6. Press the FUNC. key to settle the offset calibration
value in the ammeter.
