Good evening friends,

As i am working on ADE7763 and i successfully got the Value of Vrms and Irms ,
now i m going to read power from ADE7763,but i did not understand the way of reading power and calculation of constant(Wh/LSB).
I made following config in the ade7763 which is as following:

LineCYC: 0x00C8
Mode : 0x0080
Mask reg: 0x0014

then i m reading the LAENERGY register(0x04).but my register readings are decreasing form maximum when i increase the load.
and i really did not understand the way that how can i convert my energy readings into the power readings and also how could i calculate the wh/LSB constant for power. i did not understand why ADE7763 behaves in such a way.

Deepak
