ABSTRACT:
A probe8comprises a housing10and a member20movable with respect to the housing onto which a stylus12may be mounted such that movement of the stylus results in movement of the member and a primary transducer50, 52for measuring movement of the member relative to the housing. The member may be located in a precisely defined rest position22, 24with respect to the housing, putting the probe in a mechanical datum position. For a combined transducer probe, this enables the primary transducer52, 54to be locked while enabling use of a secondary transducer70. The primary transducer outputs can be datumed while in this mechanical datum position. Drive40, 50, 60or bias26means in one axis secure the member in its rest position in all axes.
