i am using energy meter ic evaluation board ADE7878A.
I am getting some issue in calibration of voltage as well as current.
1) i have calibrated board using Quick Setup. but what if, i want to calibrated it without quick Startup ?
2) I am using CT for current measurement i.e 200/80mA, given nominal voltage is 200V, Current as 2.6A
RMS value read by AVRMS register is 2325262 , AIRMS reg value is 1102731. what is does it means??
3) also when i try to read AWATTHR reg its value is nagative??
