I have a quick question regarding PID inputs. I hope the answer is obvious, and possibly indicative of my poor internet-search and manual-reading skills.
I’m getting dangerously close to clicking the “Square Root” checkbox option for one of my PID inputs. (I’m pumping liquid out of a spherical volume, which unfortunately is nonlinear when performing level control.) I’d simply like to know if I need to refactor the setpoint and gains to account for the square root math. Or, is all this handled behind-the-scenes, maintaining a friendly 12-inches-as-a-setpoint-means-12-inches interface.
