Introduction：
GF334 small size handheld harmonics power analyzer is suitable for power company, technical supervision department, industrial, mining, petroleum as well as chemical, home appliances and manufacturing enterprises.
Functions：
(1) 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.
(2) The value of the measurement process: it can be recorded and tested continuously of voltage,
current, active power, reactive power and other electrical parameter values and curves in a dynamic process and graphically display.
(3) To measure the instantaneous values - including the exchange parameters: U, I, P, Q, PF, phase angle, frequency, harmonics, etc.
(4) Measuring harmonics: measure/display voltage and current waveforms and harmonic bar graph.
(5) Calibrator meter: load calibration of various single phase and three phase energy meters.
(6) Vector analysis: based on the voltage, current and phase error, display vector graphics.
Features：
- Ultra-compact design, handheld, small size, light weight.
- The usage of multi-channel power supply, AC power supply can also be rechargeable battery-powered machine.
- High accuracy instrument, good stability and wide range of voltage monitoring 0-1200V, current 1mA - 20A.
- It can be divided into direct current clamp measurements and precision measurements.
- It can measure three phase voltage, current, active power, reactive power, power factor, frequency, phase, etc.
- Showing the AC waveform, vector diagram and determining the 3P3W connection errors.
- It can measure harmonics ration from 2nd to 64th and the harmonic analysis.
- The measured data can record, query and upload print.
- Instrument calibration by using software to facilitate the correction instrument variation.
