文章采用通过读取被校表和标准表同一时间的功率值来估算误差值的方法，以RN8209计量芯片为平台，设计了一款单相智能电能表自动校准软件。结果证明该校准软件不仅准确地校准电能表误差，而且提高了校表效率。%This parperr adopt the method to estimate the error value by reading the power value of correction meter and standard meter at the same time. An automated calibration software of single-phase smart electricity meter is design and im-plement in platform of RN8209. The result shows that the calibration software is not only able to accurately correct the me-ter error, but also improve the calibration efficiency, reduce costs and energy consumption.
