Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

The following characteristic specifications describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

•        

Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Typical unless otherwise noted.

AI Absolute Accuracy (Warranted)

Table 1. AI Absolute Accuracy

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

AI Absolute Accuracy Equation

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

GainError = ResidualAIGainError + GainTempco · (TempChangeFromLastInternalCal)

+ ReferenceTempco · (TempChangeFromLastExternalCal)

OffsetError = ResidualAIOffsetError + OffsetTempco ·

(TempChangeFromLastInternalCal) + INLError

                                         Random Noise ⋅   3

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.

Table 2. AO Absolute Accuracy

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

AO Absolute Accuracy Equation

AbsoluteAccuracy = OutputValue ⋅ (GainError) + Range ⋅ (OffsetError)

GainError = ResidualGainError + GainTempco ⋅ (TempChangeFromLastInternalCal) + ReferenceTempco ⋅ (TempChangeFromLastExternalCal)

OffsetError = ResidualOffsetError + OffsetTempco ⋅ (TempChangeFromLastInternalCal)

Calibration

Connect only voltages that are below these limits.

Channel-to-earth ground                                    ±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.

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.
