Absolute Accuracy Formulas

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

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

OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INL_Error

NoiseUncertainty = (RandomNoise · 3) / √ 10,000, for a coverage factor of 3 σ and averaging 10,000 points.

TempChangeFromLastExternalCal = 10 °C

TempChangeFromLastInternalCal = 1 °C
