AI Absolute Accuracy
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 | 115 | 2 | 265 | 3,225 |
5 | -5 | 115 | 2 | 148 | 1,613 |
2 | -2 | 117 | 2 | 74 | 650 |

Gain tempco | 16.7 ppm/°C |
Reference tempco | 5 ppm/°C |
Residual offset error | 12 ppm of range |
INL error | 126 ppm of range |
AI Absolute Accuracy Equation
AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty
- GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
- OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
-
NoiseUncertainty = 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 = 115 ppm + 16.7 ppm · 1 + 5 ppm · 10 = 181.7 ppm
- OffsetError = 12 ppm + 2 ppm ·1 + 126 ppm = 140 ppm
-
Noise Uncertainty = = 8 µV
- AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 3225 µV
