Functions and Features

1. The instrument is designed as a high-precision test equipment to detect grid waveform distortion occurrence, the harmonic content , voltage fluctuations and flicker and phase imbalance of power quality problems; It also includes electrical parameters testing, vector analysis functions.

2. It can accurately measure a variety of electrical parameters, such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc.

3. It can display the vector diagram of the measured voltage and current , by analyzing which users can judge if the metering device wiring is correct or not.

4. Current is measured by using the clamp transformers. You can easily and securely do the measurement, because of the use of clamp current transformers, without connecting the current loop. Depending on the user's measurement range, you can be equipped with different range of clamps.

5. Measurement and analysis of the AC power quality from the utility grid to client can be done easily, its measurement and analysis: frequency deviation, voltage deviation, voltage fluctuations, flicker, three-phase voltage unbalance factor and harmonic.

6. It can display single-phase voltage, current waveform and can display three-phase voltage and current waveform at the same time.
