IPU Activation IPU Deactivation Facet Operations Overview - Flip down Secondary Power Off switch of SCOF per ground request. Only if ground cannot power off SCOF while temperature of seed crystal is reaching 34 degrees Celsius. - Adjust focus, field of view, and interference fringes of SCOF if ground is difficult to adjust. - Remove and trash Facet Cell. Facet Cell Reorientation - Rotate Facet Cell to change samples. * Repeat experiment as ground changes experiment parameters.
