Main Features
High-intensity, high-definition, high-resolution 5.7 "(320 * 240) TFT color LCD

The system uses high-precision high-speed digital multiplier, while a measure (no) reactive power, voltage, current, frequency, phase, and all other parameters, and all the parameters of that software

No potential equipment, completely prevent the transport of equipment, such as changes in the outside world caused the error, greatly improving the system stability and reliability

Qianbiao self-calibration feature that will ensure the long-term transformer clamp-type precision stability; Minimum test current capacity: 5 A or 1 A pair of pliers, to 1 mA, in the lift at a PT, CT no circumstances do wiring load check line.
The phase between the self-test to ensure the accuracy of long-term stability of equipment

China's first system using the number of true reactive measurement technology. So that reactive measure to from voltage and current imbalance, phase asymmetry, the frequency changes and so on, the first time in the country would have no power to improve the accuracy of 0.1 percent

In -20centigrade ~ +40centigrade temperature range ensure accuracy of power (0.1 percent or 0.05 per cent). Which can carry 0.2 5 A pair of pliers (do not include all of a repetitive error, error contact with the outside world interfere with the magnetic field error, poor angle)

Which can carry 20 A, 100A, 500A, 1000A clamp, direct measurement of low-voltage integrated measurement error, and 5 A pair of pliers with CT change than direct measurement

Voltage automatic transmission 30 ~ 480 V, entered into the current 5 A. Working power-AC 57.7 ~ 480V, and can be internal battery-powered (no need external rechargeable battery charger) dual-choice

Recognition of the limits of the four common three-phase three-48, 96-phase 4-wire connection error, showed that the 2.60 arbitrary wiring plans

For each connection, display an error after the identification of 2.60 map, as a 2.60-training in the use of search plans

Can be measured three-phase voltage, current two to 51 harmonics, harmonic and storage of all data

At the same time may show that the three-voltage, three of the current wave.
Provide error correction function to facilitate the calibration error (password required)
Storage 10, 000 tables all the measurement data, including the working parameters for later analysis

And PC can communicate; It is convenient to the original database and management system interface. Can be allocated "PEC Meter Management System" software, to achieve the paperless office

Chinese character input. U disk support, through the U disk, serial software downloads upgrade calibration data

Automatically or manually check single-phase, three-phase active and reactive sensor-hour meters and electronic power meter (capable of receiving electronic pulse-hour meters)

Available contrast checks voltage, current, power, power factor, phase and frequency of electrical meters and the transmitter

Can be measured PT, CT secondary load. Check Meter constant. Quadrant Power Measurement

Can check active, reactive power meter error, while the main check, the Deputy table error and automatically calculate the estimated value of standard deviation
