■ Features

▲ Real-time detection of three-phase voltage, current, active power, reactive power, phase angle, power factor, frequency, low-voltage CT primary and secondary currents, transformation ratio, and polarity.

▲ Intuitively display the vector diagram of the three-phase voltage and current, and prompt the judgment results of 48 kinds of metering devices.

▲ It can carry out the word running test of the watt-hour meter, and investigate and deal with the electric stealing methods of the user changing the nameplate and the word wheel.

▲ Equipped with high-precision clamp-type current transformer, sampling is convenient and safe.

▲ It can detect the comprehensive errors of three-phase four-wire and three-phase three-wire metering devices (including wiring, electric energy meter, low-voltage CT errors) without power failure and without changing the wiring of the metering circuit.

▲ It can store the detection data of 2000 meters, including meter information, voltage, current, phase, power, power factor, vector diagram, etc.

▲ Built-in large-capacity lithium battery, can work continuously for 8 hours.

▲ With RS232 interface, it can communicate with computer to realize data management and report printing.

▲ It can detect the 2nd to 32nd harmonics, and display the content or amplitude of each harmonic; the degree of harmonic distortion can be automatically calculated.

▲ It can measure the transformation ratio and polarity of CT for low-voltage measurement.
