I am using ADE7878A evaluation board for Understanding of Energy meter.
I have calibrated IC using Quick Startup,
I have also calibrated Current & voltage gain registers successfully.
My nominal voltage is 200V & current 2.5 Amp
1) Now i want calibrate AWGAIN , but i am unable to understand content of AWATT & AWATTHR register??
Can anyone help me to understand it??
Input voltage Current AWATTHR Reg value
200V 2.5Amp 273
130V 2.5Amp 180
130V 1Amp 72
I am reading AWATTHR register using Line cycle accumulation mode LINECYC = d1000. LYCYMODE = 0x4F
2) Also i have a question ,when i read AWATTHR register using Line cycle accumulation mode & without Line cycle accumulation mode its content are different why so??
