features

● ac sampling calibration: the virtual load calibration method is using by three-phase source, and the real load calibration method is using by measuring current with the clamp online.

● transmitters measurement: measure the basic error, dc ripple and the response time for the transmitters.

 harmonic output: the output can load 2nd to 21st standard harmonics with adjustable amplitude and phase to test harmonic influence on the checked meters.

● value adjustment method: fixed-point, rotary encoder, step and potentiometer (option).

● phasor diagram: freely adjust the phase between the three-phase electrical parameters, and intuitively display by phasor diagram.

● excellent human-computer interaction: large lcd touch screen display, touch and button operation modes, easy for users to measure manually.

● electric energy calibration (option): calibrate a single ac electric energy meter by the standard pulse i/o interface.

● periodic meters calibration (option): the fourth voltage output can calibrate the difference of amplitude, phase and frequency for periodic meters.

● proprietary software (option): support the calibration for the checked meters by semi-automatic or full-automatic, data management and report export.
