Calculate VRMSOS in ADE7753

Hi,

We need to calculate VRMS value using ADE7753. Without VRMS calibration, We will get 0x76FF as VRMS offset value on no Input condition.

For calculating VRMSOS, V1 = 250mV = 0x1184B2 (VRMS Register Value) & V2 = 25mV = 0x01D82D

So, VRMSOS = 157783.91 = 0x26857.

VRMSOS register is 12 bit & offset value is 20-bit.

How to use CH2OS register.

Any help in this regard will be appreciated.

Regards,

Nikita
