PROBLEM TO BE SOLVED: To provide a method of operating a coordinate positioning apparatus having a surface sensor that is rotatable about at least a first axis.SOLUTION: The method comprises obtaining a first measurement result with the surface sensor at a first angular orientation and obtaining at least a second measurement result with the surface sensor at a second angular orientation. The first and second angular orientations are different from each other so that any offset of the surface sensor from an expected position has at least a partially opposing effect on the first and second measurement results. The method then compensates and/or establishes the offset using the first and second measurement results. |
