In this post I have listed a few common arguments for both field calibration and workshop calibration.
We quite often receive questions regarding the calibration of a square rooting pressure transmitter. Most often the concern is that the calibration fails too easily at the zero point. There is a reason for that, so let’s find out what that is.
