Read the manual for specific positioner but the basic is to set it within the angle travel range from 0-100 opening otherwise you cannot calibrate it, let say at 50% (12mA) signal it will be at the midway of the travel angle of the positioner and lot to set like (linear/rotary/open clockwise or CCW etc.) so you need the manual user.
