The multifunctional electric energy meter field calibrator is a portable device specially designed and developed for on-site calibration sheets, three-phase active and reactive power induction and electronic electric energy meters, and various other electrical instruments. It is widely used in industries such as electric power, metallurgy, chemical industry, tobacco, textile, railway, shipbuilding, real estate and so on. It provides a convenient solution for the power metering department to perform on-site meter error verification without dismantling the meter and without power failure, and for the power inspection department to verify the illegal acts of stealing electricity.
