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.
