■ Performance characteristics

▲ The instrument adopts a flat panel structure, a true-color 9-inch large-size LCD screen, with a high-resolution capacitive touch screen, and an embedded independent operating system.

▲ The instrument is a high-precision testing instrument that integrates power meter calibration, electrical parameter testing, and detection of power quality problems such as waveform distortion, voltage fluctuation and three-phase unbalance in the power grid.

▲ Accurately measure voltage, current, active power, reactive power, phase angle, power factor, frequency and other electrical parameters to calculate the measurement error of the test equipment loop.

▲ The vector diagram of the measured voltage and current can be displayed, and the user can analyze the vector diagram to get the correctness of the metering equipment wiring. At the same time, in the three-phase three-wire connection mode, it can automatically judge 48 kinds of connection methods, and the automatic calculation function of supplementary power is convenient for users to calculate the supplementary power for users with wiring problems.

▲ It can display single-phase voltage and current waveforms and simultaneously display three-phase voltage and current waveforms.

▲ Load fluctuation monitoring: Measure and analyze the fluctuations in the power quality of the public grid caused by various electrical equipment under different operating conditions. Record and store power parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc. Barcode scanner can be selected to automatically enter the bar code of the meter.

▲ The 485 communication interface of the electric energy meter can be tested, and can complete the work requirements of on-site verification of the multi-function (smart) electric energy meter. The demand can be checked for error according to the set demand cycle and slip time in the electric meter.

▲ 60,000 test data and results can be saved during on-site verification (you can choose to delete or delete all of them), and upload them to the computer via a U disk, and use the background management software (optional).
