The Yamata AVP103 locator that was recently debugged has good self-tuning capabilities, but there is still air output at 4 mA. What’s going on? The valve always has a slight opening, and its linear performance is not good. How to solve this?

Adjust it slowly; there should be a way to make fine adjustments

At 4mA, the positioner is adjusted so that its zero point is reached, resulting in an output of zero.....

Hold down the UP or DOWN button; once the output becomes 0, the locator will remember it on its own.

Do I need to adjust it again after making the changes?
