I'm starting with the calibration process for the ADE7758 using line cicle mode with a 300Watts, 220V load (two incandescent bulb lamps 150W each). I tried different accumulation periods and I always get pretty similar WHR/LSB constants.
I noticed I should verify that the aparent energy accumulated was the same that the active energy and in result that was not the case.
A sample measure for phase A are these:
AWATTHR = 0xFE00 = 65024d
AVARHR = 0xFF8FFF= -28673d
AVAHR = 0x115FF = 71165d
At least, all the measure seem to verify S^2 = P^2 + Q^2, just a 0.14% difference. Hope anybody could guide me with this matter.
