            1、设置参数：A)、电流、电压通道增益，有功、无功、视在等功率增益，有功、无功、视在等能量放大比例。
                         B)、有功、无功小信号偏移补偿，电流、电压小信号偏移补偿。
                         C)、相位补偿系数。
                         D)、CF1、CF2脉冲常数（分子、分母二个参数）
                         E)、设置半波能量累计的半波数。set number of half line cycles  for LWATTHR,LVARHR and LVAHR accumulators

            2、配置参数：A)、模式配置：MODE1，MODE2，WAVMODE，NLMODE，ACCMODE。
                         B)、中断使能配置：只配置CF1、CF2有无功能量计量脉冲中断。(MIRQENL，MIRQENM，MIRQENH)

            3、计量参数：A)、电流，电压，频率，有功、无功、视在等功率
                         B)、CF1、CF2脉冲中断计量有无功电能量
