FUNCTIONS

■ Check Meter - real live load calibration of various single-phase, three-phase energy meters.

■ Vector analysis - based on the voltage, current, phase error of judgment wiring, display vector graphics.

■ Measurement of harmonics - measurement / display voltage and current waveforms and harmonic bar graph.

■ Measurement the instantaneous values - including the exchange parameters: U, I, P, Q, PF, phase angle, frequency, harmonics, etc.

■ The value of the measurement process- it can be recorded and tested continuously voltage, current, active power, reactive power and other electrical parameter values and curves in a dynamic process and graphically display.

■ Measuring energy consumption values - the precise timing measurements of electrical equipment for short-term energy consumption; energy resolution: milli-watts; time resolution: milli-second; they are difficult to available for common instrument of power. The functions are used by pumping, cranes, air conditioning and other equipment in a work cycle connected power consumption.

FEATURES

■ The measured data can record, query and upload print.

■ Ultra-compact design, portable, small size, light weight.

■ It can measure harmonic content from 2 to 64 and the harmonic analysis.

■ It can be divided into direct current clamp measurements and precision measurements.

■ Instrument calibration by using software to facilitate the correction instrument variation.

■ Showing the AC waveform, vector diagram and determining the three-phase three-wire connection errors.

■ High accuracy instrument, good stability, and wide range of voltage monitoring 0-1200V, current 1mA - 1000A.

■ The usage of multi-channel power supply, AC power supply can also be rechargeable battery-powered machine.

■ It can measure three-phase voltage , current, active power, reactive power, power factor , frequency, phase , etc.
