    Note  

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

    spd-note-note
    Note  

    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.

    Note  

    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 = 295 µ V 3 100 = 88.5 µV
    • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2,710 µV

    Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    spd-note-caution
    Caution  

    This device is rated for Measurement Category I and the voltage across the isolation barrier is limited to no greater than 30 Vrms/60 VDC/42.4 Vpk continuous. Do not use for measurements within Measurement Categories CAT II, CAT III, or CAT IV.

    spd-note-note
    Note  

    Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
