Manual Edge Detection Crosshair Probe The manual edge detection crosshair includes an edge detection zone around the crosshair intersection. When the crosshair is positioned near an edge and the edge is recognized by the system, a tone is produced to alert the operator, the probe is fired and the point location is retained in the system until another edge is crossed. Single points are acquired manually or automatically in program playback (in CNC enabled systems) as the crosshair intersection passes over a feature edge. The operator must press the Enter Button or press in the Measure Prompt to enter the point.
