Furthermore, measurement errors, in particular the errors resulting from an unintentional change in a direction of movement measurement, can be shown on a display and corrected manually and / or automatically by actuators. In addition, in the event of a failure of the sensor unit with respect to the detection of the first movement characteristic with the second movement characteristic, an at least partially usable measurement result can be achieved, in particular if the second movement characteristic corresponds to the first movement characteristic.
- telbar Is a characteristic variable for a rotary movement of the housing about at least one axis from the recorded movement parameters? telbar, can be concluded simply on an undesired movement of the housing, in particular if the axis extends in the direction of the normal to the surface of the object under investigation.
