Calibration
Step 1: Long press the key for 3 second until the screen flashes
Step 2: when the digit flashing circularly, it refers to: voltage high digit→voltage middle digit→voltage low digit→→voltage decimal point→ampere high digit→ampere middle digit→ampere low digit→ampere decimal point. Short press the key to adjust the value of flashing digit.
Step 3: Long press the key for 3 second, the screen displays “pass” which means the parameter saved.
Notice: Calibration must operate under pure resistance (PF=1.00) load situation, or the error value would be higher than before.
