Patent ID: 8745889

Claim:
A method for electrically controlling a measurement stand with a movement of travel of at least one measuring probe from a pre-set starting position to a measuring position, in which method a motor is activated which, for performing at least one measurement, uses a drive unit for moving a displacement member up and down on which the measuring probe is fastened by means of a retainer, wherein the method comprises: performing a learning routine before carrying out a first measurement, the learning routine including: lowering the measuring probe with a predetermined speed of travel until the measuring probe rests on a surface of an object of measurement, activating a free-wheel mechanism between the drive unit and the displacement member after the touchdown of the measuring probe on the surface of the object of measurement, the free-wheel mechanism when activated decoupling the drive unit with respect to the displacement member, using a switching device to detect activation of the free-wheel mechanism and to provide a control signal for stopping the motor, and detecting the travel of the measuring probe between the pre-set starting position and the touchdown position when the free-wheel mechanism is activated, after which the learning routine is terminated.
