3.7. Fixed Head with Integrated Swivel Joint Probe System – This probe system shall be able to perform single probings and active scanning, and should also be capable of 15° increments of rotation and lock to normal “fixed” position accuracies. The added capability of the fixed head system should allow for more weight of stylus system capacity, stylus length and rotational ability. This system shall allow for automatic probe change and be supplied with a master reference stylus and 3 adapter plates for use.The fixed head system shall have some means of collision protection to prevent damage to the head if a collision occurs. Accuracy of this fixed head system shall be MPEE= 2.8+L/400 µm or better. If the articulating head system meets ALL accuracy specifications as stated herein, the fixed head probe system may be omitted.
