The autojoint is a highly repeatable coupling mechanism which will minimise the need for tip re-qualification after the exchange of probes or extension bars. The locking mechanism is operated by rotating an actuator contained in the mating half of the coupling, which is located on the probe or extension bar. The actuator has a drive slot which may be operated using an S10 joint key for manual probe or extension bar changing applications. Automatic probe or extension bar changing is possible using the Renishaw ACR1 or ACR3 autochange systems.
The status of the probe is indicated by the probe status LED. This is normally lit when the probe is ready for use and extinguishes as the probe triggers.
