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

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

Gain tempco 7.3 ppm/°C

Reference tempco	5 ppm/°C
INL error	60 ppm of range

AI Absolute Accuracy Equation

AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainity

GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) +

ReferenceTempco · (TempChangeFromLastExternalCal)

OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError

Random Noise ⋅ 3

NoiseUncertainty = for a coverage factor of 3 σ and averaging 10, 000 10,000 points.

AI Absolute Accuracy Example

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

GainError: 65 ppm + 7.3 ppm · 1 + 5 ppm · 10 = 122 ppm

OffsetError: 13 ppm + 23 ppm · 1 + 60 ppm = 96 ppm

NoiseUncertainty: = 8.1 μV

AbsoluteAccuracy: 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 2,190 μV

Channel to earth 11 V, Measurement Category I

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 lowvoltage sources, and electronics.

Caution Do not connect the system to signals or use for measurements within Measurement Categories II, III, or IV.

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