Abstract
A measurement point is approached with a probe head arranged on a displacement mechanism having at least two supports. An actual difference value between the displacement positions of a first and a second support is determined. A static difference value representing is provided and subtracted from the actual difference, in order to obtain a dynamic difference value representing a static difference between the first and the second displacement positions is subtracted from the actual difference value in order to obtain a dynamic difference value. The space coordinate of the measurement point is determined as a function of the dynamic difference value.
