Product features:
1, the instrument adopts flat structure, true color 9 inches large size LCD screen, with high capacitance touch screen, embedded independent operating system.
2. The instrument is a high-precision testing instrument integrating energy meter calibration, electric parameter testing and power quality problems such as waveform distortion, voltage fluctuation and three-phase imbalance in power grid.
3, accurate measurement of voltage, current, active power, reactive power, phase Angle, power factor, frequency and other electrical parameters, so as to calculate the measurement error of the test equipment loop.
4, can display the measured voltage and current vector diagram, users can analyze the vector diagram to get the metering equipment wiring is correct or not. At the same time, in the three-phase three-wire connection mode, it can automatically judge 48 kinds of connection modes, and automatic calculation function of recovery power is convenient for users to calculate recovery power for users with wiring problems.
5, can display single-phase voltage, current waveform and simultaneously display three-phase voltage, current waveform.
6. Load fluctuation monitoring: measure and analyze the fluctuation of power quality of public power grid caused by various electrical equipment in different operating states. Record and store voltage, current, active power, reactive power, apparent power, frequency, phase and other power parameters. Optional bar code scanner can automatically input the bar code of the meter.
7, the 485 communication interface of the electricity meter for detection, and can complete the on-site calibration of multi-functional (intelligent) electricity meter work requirements, according to the meter has been set in the demand period and slip time on the demand for error verification.
8. Save 60000 test data and results at the same time of on-site verification (you can choose to delete a single or delete all), and upload to the computer through THE U disk, through the background management software (optional accessories).
