The YC-1891G series is a high-performance smart electricity meter multifunctional calibration device, designed to meet the diverse needs of power supply, metering, and electricity meter manufacturing factories. It is fully capable of satisfying the various requirements for the calibration of State Grid smart electricity meters (both local and remote meters), including load switches, dual circuits, infrared communication, carrier communication, and simulated card insertion. The calibration device consists of an integrated digital synthesized sine signal source, a high-stability programmable power source, overload automatic protection circuits, current and voltage output transformation circuits, automatic pressure contact (pneumatic) for meter positions, working power supply circuits, standard electricity meters, and distributed error calculators, all of which are standard metrological instruments.
