Note Accuracies listed are warranted for up to one year from the device external calibration when the device is within 10 °C of the external calibration temperature and 1 °C of the last self calibration, when averaging 10,000 DC samples. Other accuracies may be calculated for different temperatures and sample sizes using the given equations.
AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty
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.
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 = 115 ppm + 16.7 ppm · 1 + 5 ppm · 10 = 181.7 ppm OffsetError = 12 ppm + 2 ppm ·1 + 126 ppm = 140 ppm
Noise Uncertainty = = 8 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 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.
