Quick Setup, No Repeated Laser Adjustments EUCLID is quick to setup and simple to operate. The laser and targets fit standard NAS tooling spheres. Because the precisely calibrated Reference Target measures laser position accurately, the operator only needs to position the alignment laser beam within 0.1 inch of its center. This process is quickly accomplished by monitoring the real time display on the Pendant or a computer. The operator is then ready to start the alignment process. Since the Reference Target allows the system to constantly track the position of the laser, no further laser adjustments are necessary
