For more information about absolute accuracy at full scale, refer to the AI Absolute Accuracy Example section.

Gain tempco	13 ppm/°C
Reference tempco	1 ppm/°C

Note Accuracies listed are valid for up to two years from the device external calibration.

AI Absolute Accuracy Equation

AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainity

GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
NoiseUncertainty =
$\frac{Random Noise \cdot 3}{\sqrt{10, 000}}$
for a coverage factor of 3 σ and averaging 10,000 points.

AI Absolute Accuracy Example

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

TempChangeFromLastExternalCal = 10 °C
TempChangeFromLastInternalCal = 1 °C
number_of_readings = 10,000
CoverageFactor = 3 σ

For example, on the 10 V range, the absolute accuracy at full scale is as follows:

GainError = 48 ppm + 13 ppm · 1 + 1 ppm · 10 = 71 ppm
OffsetError = 13 ppm + 21 ppm · 1 + 46 ppm = 80 ppm
NoiseUncertainty =
$\frac{281 µ V \cdot 3}{\sqrt{10, 000}}$
= 8.4 µV
AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1,520 µV
