ADE7878 Low & High (42.5 & 52.5) range Frequency issue

[panneerrajan]

Hi,

We were using ADE7878 for three phase meter application.
Meter working fine in 50Hz frequency. But at low & high range levels facing out of accuracy.
Please provide your suggstion

Thank you,
Rajan

Hi,

1) read the datasheet
2) explain what "facing out of accuracy" means. It doesn't tell anything to us. Give values with units.

Hi,
Thank you for your support,
While testing energy(kWh) in low & high level frequency input. Energy accuracy should maintain ±0.8.
But accuracy value going out of range
Thanks

Hi,

Where do you find the informations in the datasheet?
* 0.8
* 42.5
* 52.5
(--> Always give values with units)

Is your test circuit and the test signals exactely the same as in the datasheeet?
