Product features
1. The basic error of field calibration sheet, three-phase watt hour meter and power acquisition terminal.
2. Under the condition of no power cut and no change of the wiring of the metering circuit, the error of the metering device is detected, so as to judge whether the metering device is faulty.
3. Three Phase Watt Hour Meter Calibrator can measure voltage, current, power, phase angle, power factor, frequency and other electrical parameters, so as to accurately judge and detect the fault of metering device circuit.
4. Display the vector diagram of three-phase voltage and current, which can directly check the wiring error of metering device.
5. Clamp type transformer is used to measure the current loop, so that the operator can measure the current quickly, simply, safely and reliably without opening the current loop.
6. The comprehensive error of reactive energy meter can be detected without changing the wiring.
7. The Handheld power meter instrument has the functions of waveform display and harmonic analysis. The Handheld power meter instrument can display voltage and current waveforms simultaneously or separately. The instrument can analyze 1-32 harmonic content and harmonic value, and draw a histogram.
8. The three phase power quality analyser instrument has built-in EMWIN operating system, supports full spelling Chinese character input method, 7-inch true color LCD display, full touch operation and keyboard operation. The design is user-friendly and easy to operate. One screen can display a variety of electrical parameters.
9. The Power Quality and Energy Analyzer instrument supports DBF database management and query, USB disk export, Excel spreadsheet opening, and no background software operation
