Calibration of Intelligent Electric Valve Positioner

by:Sure     2021-08-13
I have been working on the instrument for more than a year, and there is an oxygen flow control valve, which uses a smart positioner. I didn't know how to verify it at the beginning. Because there are few problems, it is generally more accurate. Only recently did I find out how to calibrate correctly. Give 85% of the signal when calibrating, and then press down for three seconds to achieve automatic calibration. After calibration, it will stop automatically. Then you try again.

Then you try again, as long as 1% of the signal is applied, the regulating valve will also act.
