S/N

Function

AC power measurement has an oscilloscope function that displays the waveform of the AC signal under test in real time.

Calculate two types of harmonic distortion: THD/T (harmonic relative to full wave) and THD/F ( harmonic relative to fundamental wave).

The amplitude (RMS), content (%) and phase of the 2nd~128th harmonic of voltage or current can be analyzed in real time.

Visualize the spectrum of each harmonic in the form of a histogram (100% fundamental).


☆ Data Statistical Analysis

S/N

Function

Visual display of the measured power: The measured voltage and current measurement results are displayed at the same time

Power Trend Test: Curve the power over time in real time during the test cycle.

Power stability analysis: calculate the maximum (MAX), minimum value (min), and peak-peak value of the measured electricity ( P-P ), mean ( Avg ) , standard deviation ( S.dev ) , divergence ( Div ), etc.
