I am using ADE7758 for power monitoring.
I am trying to calibrate AIRMS of ADE7758.
As per datasheet, on page number 55, formula given for xIRMSOS, I am trying to find out the offset for my channel B.
Since the register is of 12 bit & signed thus can hold only up to -2047 with it; But as per the formula I am getting -5899 as BIRMSOS.
Following are the readings.
Itest = 1.8A BIRMStest = 43550
Imin = 0.71A BIRMSmin = 19250
As per calculations, BIRMSOS = -5899.
Please help me to solve the problem.
