AI Absolute Accuracy (Warranted)
Nominal Range Positive Full Scale | Nominal Range Negative Full Scale | Residual Gain Error (ppm of Reading) | Offset Tempco (ppm of Range/°C) | Random Noise, σ (μVrms) | Absolute Accuracy at Full Scale (μV) |
---|---|---|---|---|---|
10 | -10 | 114 | 35 | 252 | 2,688 |
5 | -5 | 120 | 36 | 134 | 1,379 |
2 | -2 | 120 | 42 | 71 | 564 |
1 | -1 | 138 | 50 | 61 | 313 |
Gain tempco | 8 ppm/°C |
Reference tempco | 5 ppm/°C |
Residual offset error | 15 ppm of range |
INL error | 46 ppm of range |
AI Absolute Accuracy Equation
AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty
- GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
- OffsetError = ResidualAIOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
-
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

AO Absolute Accuracy (Warranted)
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.
Nominal Range Positive Full Scale | Nominal Range Negative Full Scale | Residual Gain Error (ppm of Reading) | Gain Tempco (ppm/°C) | Reference Tempco (ppm/°C) | Residual Offset Error (ppm of Range) | Offset Tempco (ppm of Range/°C) | INL Error (ppm of Range) | Absolute Accuracy at Full Scale (μV) |

5 | -5 | 135 | 8 | 5 | 65 | 1 | 64 | 1,616 |
AO Absolute Accuracy Equation
AbsoluteAccuracy = OutputValue ⋅ (GainError) + Range ⋅ (OffsetError)

- OffsetError = ResidualOffsetError + OffsetTempco ⋅ (TempChangeFromLastInternalCal) + INLError
