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.
●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.
