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.

draw the block diagram of a level transmitter ?
A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
