Publication 1746-IN007C-EN-P - December 2002
The module accuracy is dependent on the RTD/Resistance type, the excitation
current, and the input filter selection. The following table shows the module
accuracy and temperature drift when the module has been auto-calibrated at the
operating temperature and when the module’s temperature changes but has not
been recalibrated.
