摘　　要：该校准仪是用于校准各种电子电压表基本误差的专用标准仪器,具有定点频率下正 弦波信号输出的标准电压源。校准仪内设有热点转换器式电压基准,可以准确地校准各频率点 的输出电压值。该仪器采用微差法计量原理设计的误差电路,能直读被校表偏离定点电压的误 差值。This normalizing device is a standard instrument used to calibrate the intrinsic errors of the various kinds of electronic voltmeters. It shows the standard potential source in the form of sinusoidal wave signals at fixed-point frequency. The hot-point converter style the output voltage at various frequencies. voltage reference inside the device can accurately calibrate
