PRT/RTD Temperature Accuracy
Accuracy is for 4-wire 100 Ω nominal PRT/RTD, using medium or slow sample rate. 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. When using the Fast sample rate, add the number given in the table to the
accuracy specification. 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.

Thermistor Resistance Accuracy
Accuracy is given as ± (% of measurement + Ω). The basic accuracy specification is for 4-wire thermistor, slow sample
rate. When using medium or fast sample rate, add the number given in the table to the accuracy specification. If the
environment temperature is outside the specified range, multiply the temperature coefficient numbers by the temperature
deviation and add to the accuracy specification. For 2-wire thermistor add 0.02 Ω internal resistance if using Channel 1 or
1.5 Ω if using channels x01 through x20, and add external lead wire resistance.
