Calibrating Output Settings
Preparation
The following measuring devices are required for calibration.
1.
Digital Multimeter for Voltage/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)
2.Shunt Resistor for Current Measurement- 1 set
10A/50mV 0.1% accuracy (400H/HA)
25A/50mV 0.1% accuracy (800H/HA)
50A/50mV 0.1% accuracy (1600H/HA)
Offset/Full Scale Calibration of Output Voltage Settings
1. Disconnect the load wires and remote sensing wires.
Connect the digital multimeter to the output terminal.
4.Press the FUNC. key and change the top Number
Display to Settings Item 20 with the VOLTAGE
dial.
In advance, turn POWER switch ON and OUTPUT OFF.
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 press the
OUTPUT key to set output to ON.
5.Adjust so that the digital multimeter (used for
output voltage measurement) displays “0.100V”
with the CURRENT dial.
6 . Press the FUNC. key to complete offset
calibration of the output voltage settings.
FUNC. lamp will light and the display at bottom Number Display
will disappear.
