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.
