Description
This parameter is added to the Watt calculation for element 0 to compensate
for input noise and truncation.
LSB = (VMAX*IMAX / In_8) *7.4162*10^-10 W
This parameter is added to the Watt calculation for element 1 to compensate
for input noise and truncation.
LSB = (VMAX*IMAX / In_8) *7.4162*10^-10 W
This parameter is added to compensate for input noise and truncation in the
squaring calculations for I². QUANT_IA affects only I0SQSUM and I1SQSUM.
LSB = (IMAX²/In_8²)*7.4162*10^-10 A²
This parameter is added to compensate for input noise and truncation in the
squaring calculations for I². QUANT_IB affects only I0SQSUM and I1SQSUM.
LSB = (IMAX²/In_8²)*7.4162*10^-10 A²
