On the ADE7953 our readings are approximately 30% high. We're trying to understand why and thats raised some questions about the math in the ADE7953. The datasheet says with a fullscale input, the sample max is 6,500,000 but the RMS is 9,032,007. How is the RMS greater than the peak? Shouldnt the RMS be ~4,596,194 (peak divided by root 2)?
