3-Phase Digital Power Meter (Model: PM9833)
1.Introduction
The digital power meter is not only used to measure the single-phase measurement function of each input unit, but also the measurement function (∑) function of a wiring group composed of multiple input units. It can be used to test the AC voltage (U), AC current (I), power factor (λ), active power (P), apparent power (S), reactive power (Q), phase difference (Ø) and frequency (FU).
7 windows on the panel simultaneously display various parameters of each phase and the measured signal values are all true RMS values which is also applicable to the wave-distorted signal.
