Prooblem in reading Total Kwh in ATM90E32 (APenergyT).

[RamyaDidde]

Hello

I am Using ATM90E32 IC. I am reading each phase energy and Total energy(APenergyT). I am using a reference energy meter. When comparing both the Energies, Their is huge difference between the energies of ATM90E32 IC and reference energy meter. I am able to read the voltage and current, each phase energy is also matching. But the Total Kwh is not matching. Someone please help me to read the energy from the ATM90E32 IC.

Thanks & Regards
Ramya.
