Datum Sphere
The Renishaw universal datum sphere enhances the performance
of manual and fully automated CMMs. It allows for quick and
easy adjustment to set ball stem over a wide range of probe
datuming angles. This enables datuming above, centrally and
below the ball. Each datum sphere is supplied with its own
certificate, giving ball diameter and roundness. All sphere
measurements are performed on equipment traceable to UK
(NPL) standards.
