1. A probe head for coordinate-measuring instruments having a probe-suspension system which defines a three-dimensional coordinate system and is adapted to carry a probe (14) which can be deflected in all three coordinate directions in space, characterized by the fact that, for each of the three coordinate directions (6, 15, 16), a separate taring device including an adjustable spring system is provided with means for automatically setting the zero position of the spring system, whereby the probe head is automatically adjusted for tare, whatever the spatial orientation of the probe head.
