I’d like to ask everyone for advice on calibrating the zero point and range of differential pressure transmitters! !

Is there any difference between using the options for adjusting the range and zero point on the Hart handheld controller, and directly adjusting the transmitter’s range and zero point from within that same controller? Which one is correct, thank you! ! !
The Hart handheld controller has options for adjusting the range and zero point. Adjust the transmitter range and zero point directly from the handheld controller. Is the Hart handheld operator the same thing as a regular handheld operator? What do you want to express?

The handheld controller is only used to set the range, not for calibration; the calibration of the transmitter’s range requires applying pressure.
What do you mean? Are you asking about the difference between using a plotter and an indicator head?
Do you mean that one is to set the range zero point directly in the automatic settings, while the other requires entering the manual settings menu to make the adjustment? Both are the same; it depends on what’s more convenient for you to use. If accuracy is important, then the key lies in whether the pressure application equipment is of good quality
