Abstract / Hauptanspruch
A measurement probe, such as a touch trigger probe, is described that comprises a stylus module (22; 122) attachable to a base module (20;120). The stylus module (22;122) comprising a housing and a stylus holder (24; 132) moveably attached to the housing. The base module (20; 120) comprises a measurement portion (36;124) for generating measurement data indicative of movement of the stylus holder (24;132) relative to the housing. The stylus module (22;122) has an inbuilt failure mode and thereby a substantially predetermined operational lifetime. In one embodiment, the inbuilt failure mode is provided by integrating a battery (34) into the stylus module (22). Providing a mechanical failure mode in which a component of the stylus module (122) catastrophically fails after a certain amount of usage is also described.
