Calibrating Meters
Preparation
The following measuring devices are required for calibration.
1.Digital Multimeter for Voltage/Current Measurement- 1 set
2. Shunt for Current Measurement – 1 set
No. of Display Digits : 5 1/2 or more
Display Accuracy : 0.005% or more
(Possesses a measuring range from 1mV~1000V)
10A/50mV 0.1% accuracy (400H/HA)
25A/50mV 0.1% accuracy (800H/HA)
50A/50mV 0.1% accuracy (1600H/HA)
Voltmeter Offset/Full-Scale Calibration
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. Press the PRESET key ① and set to “0.1V” with the
VOLTAGE dial ② and “1.00A” with the CURRENT
dial ③.
(See Operating as Constant Voltage Power Supply
under Basic Operations on how.)
3.Press the PRESET key again and then the OUTPUT
key to set the output to ON.
4. Press the FUNC. key and change the top Number
Display to Settings Item 24 with the VOLTAGE dial
to display the voltage measurement value at the
bottom.
5. Adjust the measurement value displayed in the
bottom Number Display to the same value as
displayed on the digital multimeter (used for output
voltage measurement) with the CURRENT dial.
