Three-phase three-wire test: 

connecting the measured wire UA 

yellow, UB green, UC red corresponding to U1 red, COM black, U2 red   

jack of the instrument, clamp wire IA, IC respectively by current clamp I1, I2. 

To test three-phase three-wire voltage, current, phase, phase sequence, 

frequency, power, power factor, etc. As showed below: (the two COM ports 

of the instrument is internally short circuited, connect either of them to null 

line N)
