DF6373 Three Phase Smart Meter On-site Calibrator

Manufactured in the testing and calibration of the 0.1 Class(and below) single phase meter and three phase meter, the DF6373 three phase smart meter on-site calibrator has the functions of meter accuracy test, electrical parameter test, transformation ratio test, harmonic test, correction of the wrong connection, data storage and reading, etc.

Overview

Key Features

Technical Parameters

Physical Dimension

●With the application of the digital reactive measurement technology, the test process of the equipment won’t be affected by the unbalance of the voltage¤t, the unsymmetry of phase angle and the frequency changing;

●The equipment can test active(reactive) power, voltage, current, frequency and phase , it also has the all parameter software modification function;

●High brightness, high definition, high resolution(No less than 640*480),large color LCD display;

●Wide working voltage range: AC 30～480V.The equipment can ensure the accuracy of the energy metering;

●The equipment can test the positive sequence, negative sequence, zero sequence and the imbalance of the voltage and current;

●Voltage auto-switch:0-480V, Current input(direct):5A;

●Equipped with the 0.2 Class 5A Clamp Meter, the equipment can test the switching none repeating error, contact error, angle error. etc.

●With the light and beautiful design of the appearance, the equipment is convenience for using in the field.
