Input Module Option Specifications
The Product specifications describe the Absolute Instrumental Uncertainty of the
Product at 95 % level of confidence (coverage factor k = 2) within one year from
calibration. The Input Module specifications include calibration uncertainty,
linearity, repeatability, resolution, stability, and environmental temperature effects
from 13 °C to 33 °C.

Notes
• Specifications stated in percent are percent of reading.
• If the environment temperature is outside the Performance Environment Range but within the Operating Environment
Range, multiply the accuracy specifications by 1.5.
• Reference Input Temperature Accuracy assumes a 4-wire, 100 Ω, α = 0.00392 PRT. The specification does not include
accuracy of the thermometer (see Table 4 of this manual).
• DUT Input Resistance Accuracy specification for 2-wire sensors is 0.05 Ω plus lead wire resistance.
• Thermocouple Input Temperature Accuracy specification includes Thermocouple Input mV and Reference Junction
Temperature, combined using the root-sum-square method. The specification does not include the accuracy of the
thermocouple.
