• Can be used as a standard meter for AC energy meter calibration devices that meet the requirements of R46.

• Suitable for calibrating single/three phase standard voltage sources and standard voltmeters of class 0.05 and below (with stable voltage source).

• Suitable for calibrating single/three phase standard current sources and standard ammeters of class 0.05 and below (with stable current source).

• Suitable for calibrating single/three phase power sources, power meters, standard energy meters of class 0.05 and below (with stable power source).

S/N

Function

The measuring channel has the function of oscilloscope, which can display the waveform of the measured power in real time.

Accurately measure the phase between the voltage and current of each phase, and visually display it through the form of phasor diagram.

Two types of harmonic distortion, THD/T (harmonic relative to full wave) and THD/F (harmonic relative to fundamental wave), are calculated.

The amplitude (RMS), content (%) and phase of the 2nd ~ 63th harmonic wave of each phase voltage or current can be analyzed in real time.；

It is used to check whether the harmonic content and phase of complex waveform output of R46 device meet the requirements of the regulation.

The spectrum of each harmonic is visually displayed in the form of a bar chart (the fundamental wave is 100%).

S/N

Function

Statistical Analysis of Data: calculate the maximum value (Max), minimum value (Min), peak-peak value (P-P), average value (Avg), standard variance (S.dev), etc.

Power Stability Test: In the test cycle, real-time plot the curve of power change with time.

Normal Distribution Histogram: Displays the distribution of the collected power within a test period.

Power Stability Test: the output power stability of the inspected electric energy device can be calculated automatically.
