Abstract
A probecomprises a housingand a membermovable with respect to the housing onto which a stylusmay be mounted such that movement of the stylus results in movement of the member and a primary transducerfor measuring movement of the member relative to the housing. The member may be located in a precisely defined rest positionwith respect to the housing, putting the probe in a mechanical datum position. For a combined transducer probe, this enables the primary transducerto be locked while enabling use of a secondary transducer. The primary transducer outputs can be datumed while in this mechanical datum position. Driveor biasmeans in one axis secure the member in its rest position in all axes.
