Hi ALL,

 

I have a problem during calibrating for ADE7878:

 

I used the AN-1076 to calibrate ADE7878 and xVRMS, xIRMS, xWATTHR operates right after the calibration but the xWATT registers always give the wrong values (the register alway give values which are approximately equal to 1/3 of real values). I already got stuck with this for 2 weeks and I don't know how to fix it. So, I hope that someone met this problems before and help me to solve the problems.

 

Thanks so much!
