    AI Absolute Accuracy (Warranted)


    Accuracies listed are valid for up to one year from the device external calibration.


    The input/output channels of this device are not protected for electromagnetic interference due to functional reasons. As a result, this device may experience reduced measurement accuracy or other temporary performance degradation when connected cables are routed in an environment with radiated or conducted radio frequency electromagnetic interference. To ensure that this device functions within specifications in its operational electromagnetic environment and to limit radiated emissions, care should be taken in the selection, design, and installation of measurement probes and cables.

    Table 1. AI Absolute Accuracy
    Nominal Range Positive Full Scale (V) Nominal Range Negative Full Scale (V) Residual Gain Error (ppm of Reading) Residual Offset Error (ppm of Range) Offset Tempco (ppm of Range/°C) Random Noise, σ (μVrms) Absolute Accuracy at Full Scale (μV) Sensitivity (μV)
    10 -10 75 20 34 229 2,690 91.6
    5 -5 85 20 36 118 1,410 47.2
    1 -1 95 25 49 26 310 10.4
    0.2 -0.2 135 40 116 12 88 4.8

    Sensitivity is the smallest voltage change that can be detected. It is a function of noise.

    Gain tempco

    7.3 ppm/°C

    Reference tempco

    5 ppm/°C

    INL error

    76 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 = Random Noise 3 100 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 = 100
    • CoverageFactor = 3 σ

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

    • GainError = 75 ppm + 7.3 ppm · 1 + 5 ppm · 10 = 132 ppm
    • OffsetError = 20 ppm + 34 ppm · 1 + 76 ppm = 130 ppm
    • NoiseUncertainty = 229 µ V 3 100 = 68.7 µV
    • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2,690 µV
