Product Description


JWT3603 portable single-phase watt-hour meter calibrator is a kind of portable hand-held multi-function instrument used in the on-site calibration of AC single-phase watt-hour meter. This calibrator adopts intemationa1ly advanced new-generation digital processing technology and possesses such features as small size, multiple functions, high accuracy and so on. The device not only has the function to calibrate watt-hour meter, but also can measure RMS voltage and RMS current, active power, power factor, and also can store the on-site measurement data and transmit the stored data to computer. The device is equipped with precision clamp current transformer to perform on-site calibration of watt-hour meter while without having to dismount the watt-hour meter or cut off power source and measure the voltage, current,power,and power factor.
