This instrument can test two AC voltage, current, phase between
voltage, phase between current, phase between voltage and current,
frequency, active power, reactive power, apparent power, power factor,
three-phase current vector sum, distinguish phase sequence, inductive,
capacitive circuit, etc.
Test connections as follow:
Single-phase test:
connecting the measured wire L/N corresponding
to U1 red/COM black jack of the instrument, clamp L wire by current clamp
I1. To test the single line voltage, current, phase, frequency, power
parameters, etc. Also can connect U2 red, COM, I2 to test. As showed
below:
Three-phase four-wire test:
connecting wires in two steps to test
three-phase four-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)
