RTD Sensor can't be calibrate , you can only calibrate the transmitter only by potentiometer according to PT100, PT1000, ...... table.

or you can use comparison calibration.

Answer / ahmallam

RDT sensor can't calibrate , only RTD transmitter can
calibrate by RTD (PT100, PT1000, .... ) table by using
potentiometer.

or by using comparison calibration.

Answer / carl_ellis

An RTD is 'calibrated' by heating or cooling it to various
temperatures, measuring its resistance at those
temperatures, and the recording and analyzing the measurment
results.

An RTD's performance can not be adjusted like a temperature
transmitter's output can be adjusted, but its performance
can indeed be measured in a periodic calibration.

Answer / ajay kumar gupta

An RTD is 'calibrated' with the help of Temp. bath by selecting required temprature. You can compare RTD resistance, RTD Chart accordind to type RTD. There is no adjustment in RTD.
 Before installation RTD in field this checking is must.
