System calibration

The REVO-2 datum sphere is used to calibrate the REVO-2 head as well as RSP2 and RSP3-x probe configurations.

The SFP1 is calibrated using the SFA that is fixed to the MRS rail.

For the minimum required CMM volume please refer to the table and diagram below:

Probe typeA (in mm) - Ø30 sphereA (in mm) - Ø45 sphere
RSP2 with RSH175420*435*
RSP2 with RSH250570*585*
RSP2 with RSH350770*785*
RSP2 with RSH450970*985*
RSP2 with RSH5001070*1085*

* For a Ø6 mm × 10 mm stylus.
