Calibrating Slave Unit Output Settings
Calibrate the Slave unit to match the Slave’s output voltage in series operation with the Master’s voltage.
Preparation
The following measuring device is required for calibration.
Voltage Measuring Digital Multimeter 2 devices
No. of Display Digits: 5 1/2 or more Display Accuracy : 0.005% or more
* (30V/60V Type
：
Equipped with a measuring range from 1mV to 100V)
(500V Type ： Equipped with a measuring range from 1mV to 1000V)
Offset/Full Scale Calibration of Slave Unit Output Voltage
1. Disconnect the load wires and the remote sensing
wires. Connect the digital multimeter to the output
terminal of the Master and the Slave respectively.
Turn the POWER switch ON and OUTPUT OFF in
advance.

2. At the Master, set the constant voltage setting
value to [ xV ] and the constant current setting
value to [ yA ] and set the output to ON.
30V Type 60V Type 500V Type
[xV] 0.01V 0.01V 0.1V
[yA] 1.0A 1.0A 0.1A
120V Type 400V Type
[xV] 0.1V 0.1V
[yA] 0.1A 0.1A

Power Supply under Basic Operations.(page28)
3. Press the FUNC. key of the Slave.
4. Turn the VOLTAGE dial of the Slave unit to display
the setting item number 37 in the Number Display
(voltage).
* At that time, turn off the Number Display (current).
5. Adjust the CURRENT dial of the Slave so that the
display of the digital multimeter for output voltage
measurement is the same as the display of the
digital multimeter for output voltage measurement.
6. Press the FUNC. key of the Slave unit to set the
offset calibration value of output voltage setting.
7. At the Master, set the constant voltage setting
value to [ xV ] and the constant current setting
value to [ yA ] and set the output to ON.
30V Type 60V Type 500V Type
[xV] 30.00V 60.00V 500.0V
[yA] 1.0A 1.0A 0.1A
120V Type 400V Type
[xV] 120.0V 400.0V
[yA] 1.0A 0.1A
