Unlock and disable the Auto Focus mode with a single press. The Auto Focus mode uses contrast sharpness recognition to determine the optimum focus as the z-axis is raised and lowered to sweep back and forth through the focus range of the video camera. The Auto Focus mode is used in manual and CNC enabled systems to perform two functions: • Focus assist • Focused feature measurement Focus Assist Focus assist determines the z-axis position of optimum part focus as the z-axis is moved up and down and the video camera system is swept back and forth through the focus region. In manual systems, the user raises and lowers the z-axis. When the optimum point of focus has been determined by the system, the Stage Position indication in the measure prompt is changed to show only the z-axis focus target. The user then raises or lowers the z-axis to reduce the target value to zero at optimum focus. In CNC enabled systems, the system drives the z-axis to find and set the optimum focus point automatically.
