Description
0x2F
QUANT
0
This parameter is added to the Watt calculation to compensate for input noise
and truncation.
LSB=(VMAX*IMAX / In_8) *1.04173*10
-9 W
0x34
QUANT_VAR
0
This parameter is added to the VAR calculation to compensate for input noise
and truncation.
LSB = (VMAX*IMAX/In_8) * 1.04173*10
-9 W
0x35
QUANT_I
0
This parameter is added to compensate for input noise and truncation in the
squaring calculations for I
2 and V2.
LSB=VMAX
2*1.04173*10-9 V2
LSB= (IMAX
2/In_82)*1.04173*10-9 A2
0x3B
KVAR
6448
Scale factor for the VAR calculation. The default value of KVAR should never
need to be changed.
0x64
QUANT_V3
0
Offset for low-current measurement on V3.
LSB = = 9.4045*10
