Abstract:
A device for calibrating a position sensor with respect to a point of origin in a system for determining a position of an object member which is displaceable within a displacement range, said system including a stop means in proximity to an end of said displacement range, wherein said position sensor generates an output indicative of the position of said object member, said device comprising:means for displacing said object member into an abutting relationship with said stop means;means for detecting a position of said object member when abutting said stop means; andmeans for setting the point of origin of said position sensor at the detected position of said object member when abutting said stop means;wherein said means for displacing said object member continues to drive said object member into said stop means while said means for setting the point of origin sets said point of origin.
