REVO-2 calibration
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 SFP2 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 type | A (in mm) - Ø30 sphere | A (in mm) - Ø45 sphere |
RSP2 with RSH175 | 420* | 435* |
RSP2 with RSH250 | 570* | 585* |
RSP2 with RSH350 | 770* | 785* |
RSP2 with RSH450 | 970* | 985* |
RSP2 with RSH500 | 1070* | 1085* |
* For a Ø6 mm × 10 mm stylus.

NOTE: The calibration diameter of the sphere is engraved on the stem. Please ensure the exact value is used when commissioning the system.
The REVO datum sphere kits consist of the following:
Part description | Technical specification |
Datum ball | Ø30 mm or optional Ø45 mm |
Fixing studs (adaptor studs) | M6 × 1 |
Fixing studs (adaptor studs) | M8 × 1.25 |
Fixing studs (adaptor studs) | M10 × 1.5 |
Fixing studs (adaptor studs) | 5/16 in UNC (double groove)* |
Fixing studs (adaptor studs) | 3/8 in UNC (single groove)* |
Base | Ø60 mm |
C spanner | n/a |
Tommy bar (×2) | n/a |
* NOTE: Grooves on the fixing stud are to differentiate between metric and imperial measures. They are not a functional feature.
Fitting the REVO datum sphere
