Abstract

A probe 8 comprises a housing 10 and a member 20 movable with respect to the housing onto which a stylus 12 may be mounted such that movement of the stylus results in movement of the member and a primary transducer 50, 52 for measuring movement of the member relative to the housing. The member may be located in a precisely defined rest position 22, 24 with respect to the housing, putting the probe in a mechanical datum position. For a combined transducer probe, this enables the primary transducer 52, 54 to be locked while enabling use of a secondary transducer 70. The primary transducer outputs can be datumed while in this mechanical datum position. Drive 40, 50, 60 or bias 26 means in one axis secure the member in its rest position in all axes.
