A method of adjusting for a shift of the position of a stylus tip and a deviation of the zero point of a displacement detector which are caused by an exchange of a stylus of a tracer head. The shift of the position of the stylus tip and the deviation of the zero point of the displacement detector are electrically or mechanically read out as displacement. In accordance with the displacement, the tracer head assembly is moved relative to a machine frame to adjust the tip of the stylus to its reference position.
