Hi,

We were using ADE7878 for three phase meter application.
Meter is working fine in 50Hz frequency. But at low & high range frequency (47.5 & 52.5Hz) levels facing out of accuracy.
Meter able to read low & high range & show value in frequency parameter.

But while taking accuracy in low & high range frequency, Energy going to out of accuracy

Please provide your suggestion for the issue

Thank you,
Rajan
