4 Calibration 

Following the image below, connect a 5 digit displayed volt meter and current meter, please resistance (10Ω/100W) into the 

output terminals. To calibrate, start from point of zero voltage - voltage coefficient –and zero current – current coefficient. 

Hold the 

SET 

button to switch on power supply until “REF” is displayed in LCD to enter calibration mode.

4.1 Voltage Calibration

The power supply displays
