Abstract
A method for measuring the coordinates of workplaces on a coordinate-measuring device has a probe head including a probe and a probe sensor associated therewith. The method includes generating a probe signal when the probe contacts a workpiece. From this signal, dimensional values are determined that represent the position of the probe head when the workpiece is contacted. The probe head additionally includes an acceleration sensor generating an acceleration signal when the probe head accelerates, wherein the probe signal and the acceleration signal are fed to a control and analysis unit for analysis. This unit determines the dimensional values so that an analysis signal is determined by subtracting the probe signal and the acceleration signal from each other, and the dimensional values representing the position of the probe head when contacting the workpiece are determined only using the analysis signal.
