Description
These parameters are added to the Watt calculation to compensate for input
noise and truncation.
LSB=(VMAX*IMAX / IA_8) *7.4162*10
LSB=(VMAX*IMAX / IB_8) *7.4162*10
These parameters are added to the VAR calculation to compensate for input
noise and truncation.
LSB = (VMAX*IMAX / IA_8) * 7.4162*10
LSB = (VMAX*IMAX / IB_8) * 7.4162*10
These parameters are added to compensate for input noise and truncation in
the squaring calculations for I
