Claim:
1. A method for measuring an object using a coordinate positioning apparatus comprising a platform, a measurement probe having a replaceable stylus, and a probe head for reorienting the measurement probe relative to the platform, the method comprising the steps of: (i) taking a first calibration data set for the coordinate positioning apparatus that comprises datum data for a plurality of orientations of the measurement probe, the first calibration data set defining a calibration of the coordinate positioning apparatus when the measurement probe comprises a first stylus, and the datum data including first datum data for a first nominal orientation of the measurement probe; (ii) replacing the first stylus of the measurement probe with a second stylus that is nominally identical to the first stylus; (iii) updating the first calibration data set to generate a second calibration data set that defines the calibration of the coordinate positioning apparatus when the measurement probe comprises the second stylus, the step (iii) comprising the steps of: (iv) using the coordinate positioning apparatus, with the second calibration data set, to measure an object.
