PRT/RTD Resistance Accuracy
Accuracy is given as ± (% of measurement + ohms). Basic accuracy is for 4-wire PRT/RTD using medium or slow sample
rate. 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. When using Fast sample rate add the number
given in the table to the accuracy specification. The 4 k
Ω
range accuracy specification can be decreased by 0.06
Ω
if
using Slow sample rate. If the environment temperature is outside the specified range, multiply the temperature coefficient
numbers by the temperature deviation and add to the accuracy specification.
