- Page 37 4. Design and Function 8. Conversion The EMF-temperature characteristics of thermocouples are non-linear and the CTR3000 uses standard algorithms (from IEC584) to convert the measured EMF to a temperature. Thermocouples can be calibrated individually to achieve better measurement uncertainty. The calibration is presented as a deviation function polynomial.
