一种用 Z80单板机控制的电表校验仪由无锡电表厂研制成功。该仪器有标准信号发生和误差检测两种工作方式,可用于交、直流电压表、电流表、频率表、单相及三相功率表、功率因数表的点盘与校验。自动化程度高,提高了校验设备的精度。
A kind of meter calibrator controlled by Z80 single board machine was successfully developed by Wuxi Ammeter Factory. The instrument has a standard signal generation and error detection of two working methods can be used for AC and DC voltmeter ammeter frequency table single-phase and three-phase power meter power factor meter point disk and calibration. High degree of automation to improve the accuracy of calibration equipment.
