Heidenhain’s ND1200 QUADRA-CHEK metrology digital readout supports up to four axes and functions as a measuring computer for 2-D geometries. The device, which contains a dark gray faceplate, is suited for optical comparators, measuring microscopes, and 2-D measuring machines. An operator guidance system provides information about the various functions. A flat-panel LCD screen displays values, dialogs and inputs, graphics functions, and soft keys. Predefined features include point, line, and circle; a Measure Magic function selects the feature that best matches the shape implied by the points probed. Optional edge detection allows users to capture measurement points automatically via an optical edge detector.
