After getting  WH/LSB constant, i need to calculate the WTHR value and write it into the corresponding register inside ADE7880. As the example in ADE7880 calibration app note page 13, Wh/LSB = 9.6262 * 10^-5. From here, what will be the n value in WTHR calculation equation 26 page 47, ADE7880 datasheet. If n = -5 under this case, then can the fact diminishing 9.6262 to 1 cause any error?
