=±2mV
and
OffsetError=1.5•Differential(DF)Resolution+1µV
=(1.5•167µV)+1µV
=2515µV=0.252mV
Therefore,
Error=GainError+OffsetError
=±2mV+0.251mV
=±2.252mV
In contrast, the error for a 1000-mV input under the same constraints is ±0.451
mV. Figure Voltage Measurement Accuracy
(p. 285) illustrates the total error with
respect to voltage measurements for the ±5000-mV and ±1000-mV ranges.
