A modern transmitter is usually advertised as being smart and very accurate. Sometimes people may say that there is no need to calibrate smart transmitters.

What are WirelessHART transmitters?
Why do they need to be calibrated?
How is the calibration done?
Example: calibrating Emerson 648 WirelessHART temperature transmitter
