High Accuracy Grade of 0.01 Stationary Single-Phase Reference Standard Meter
GENY’s reference standards adopt unique sampling technology, with high accuracy, wide testing range. They are suited for electric power utilities, energy meter manufactures, measuring and quality examining departments using as standards.
SZ-01A-K3E wide-range standard meter uses the newest electric technical in the world. The core of SZ-01A-K3E is high-speed DSP、CPLD and MCU, it has the high-speed A/D converter with self-calibration at the same time. It can sample AC signal in high speed and deal with it in special way by DSP, this makes the circuit much simpler. It can calculate and measure AC signal exactly.
