The probe pin (19) is movably attached to the probe head (2). In the method, the probe pin for measuring the workpiece (15) can touch down on the surface of the workpiece to be measured or can be lifted off of this surface. The speed of measurement is increased by selecting the angle (.alpha.down, .alpha.up) between the direction of movement vres of the probe head (2) when touching down or when lifting off and the projection of the direction of movement toward the plane tangential to the workpiece surface in the touchdown/liftoff point (Pdown, Pup) to be less than 30.degree..
