Measurement- 1 set
No. of Display Digits: 5 1/2 or more
Display Accuracy: 0.005% or more
(Equipped with a measuring range from 1mV to
1000V)
2. Shunt Resistor for Current Measurement- 1 set
30-200 30-400 60-100 60-200
200A/50mV 500A/50mV 200A/50mV 200A/50mV
500-12 500-24 1000-6 1000-12
15A/50mV 30A/50mV 10A/50mV 15A/50mV
*Please use the 0.1-class product.
Voltmeter Offset/Full-Scale Calibration
Note: Before performing this operation, be sure to perform Offset/Full-scale Calibration (page162) of output voltage
setting.
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 24 in the Number Display
(voltage).
* At that time, the voltage measured value is
displayed in the Number Display (current).
* The figure above is an example of connecting (HX030-200G4)
5. Adjust the CURRENT dial so that the voltage
measured value displayed in the Number
Display (current) is the same as the actual
output voltage value (digital multimeter
measurement).
* The figure above is an example of connecting (HX030-200G4)
6. Press the FUNC. key to settle the offset
calibration value in the voltmeter.
