AI Absolute Accuracy

Table 1. AI Absolute Accuracy

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

Gain tempco                                                    8 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) + NoiseUncertainty

GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal)

+ ReferenceTempco · (TempChangeFromLastExternalCal)

OffsetError = ResidualAIOffsetError + OffsetTempco ·

(TempChangeFromLastInternalCal) + INLError

                                         Random Noise ⋅   3

NoiseUncertainty =  for a coverage factor of 3 σ and averaging

100 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 = 114 ppm + 8 ppm · 1 + 5 ppm · 10 = 172 ppm

OffsetError = 15 ppm + 35 ppm ·1 + 46 ppm = 96 ppm

Noise Uncertainty =  = 7.6 µV

AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2688 µV

Analog Output

AO Absolute Accuracy

Absolute accuracy at full-scale numbers is valid immediately following self calibration and assumes the device is operating within 10 °C of the last external calibration.

Table 2. AO Absolute Accuracy

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

AO Absolute Accuracy Equation

AbsoluteAccuracy = OutputValue ⋅ (GainError) + Range ⋅ (OffsetError)

GainError = ResidualGainError + GainTempco ⋅ (TempChangeFromLastInternalCal) + ReferenceTempco ⋅ (TempChangeFromLastExternalCal)

OffsetError = ResidualOffsetError + OffsetTempco ⋅ (TempChangeFromLastInternalCal)
