PRT/RTD Resistance Accuracy
Accuracy is given as % of measurement or ohms, whichever is greater. Basic accuracy is for 4-wire PRT/RTD. When
using 3-wire PRT/RTD add 0.013
Ω to the accuracy specification for internal resistance mismatch and voltage offset if
using Channel 1, or add 0.05 Ω if using channels x01 through x20. If the environment temperature is outside the specified
range, multiply the temperature coefficient numbers by the temperature deviation and add to the accuracy specification.

Note:

Ω . For disturbances >3 V, accuracy
is unspecified.
PRT/RTD Temperature Accuracy
Accuracy is for 4-wire 100 Ω nominal PRT/RTD
.
When using 3-wire PRT/RTD add 0.039 °C to the accuracy specification
for internal resistance mismatch and voltage offset if using Channel 1, or add 0.15 °C if using channels x01 through x20. If
the environment temperature is outside the specified range, multiply the temperature coefficient number by the
temperature deviation and add to the accuracy specification. Linear interpolation may be used between points in the table.
Specifications do not include sensor accuracy. The practical range of temperature measurement depends on the sensor
and characterization.
