We look at the data sheet of the ADE7953.
Please teach me method of calculating the IRMS.
Is 'Calculation of IRMS' 200ms product-sum calculation?
(10 waveform at the time of 50Hz, 12 waveform at the time of 60Hz)
If so, I do not know the meaning to check the zero-crossing point.
Please kindly teach me the reason.
