Description
This parameter is added to the Watt calculation to compensate for input noise
and truncation.
LSB=(VMAX*IMAX / In_8) *1.04173*10
This parameter is added to the VAR calculation to compensate for input noise
and truncation.
LSB = (VMAX*IMAX/In_8) * 1.04173*10
This parameter is added to compensate for input noise and truncation in the
squaring calculations for I
Scale factor for the VAR calculation. The default value of KVAR should never
need to be changed.
Offset for low-current measurement on V3.
