Edge Detectors
Use optical edge detection to increase throughput, accuracy, repeatability and
reduce operator fatigue. Optical edge detection recognizes light-to-dark or dark-
to-light edge crossings on projection-based measuring machines. Each time a
light-to-dark (or dark-to-light) is detected the QC200 identifies a point.
Manual edge detection
Manual optical edge detection recognizes light-to-dark or dark-to-light edge
transitions. As each transition is detected a bell tone sounds. The operator must
then press the enter key to accept the point.
Auto edge detection
Enter points automatically using auto edge detection. Auto edge detection
recognizes light-to-dark or dark-to-light edge transitions and automatically en-
ters the point. Each time an edge is crossed a point is entered.
To toggle between auto edge and manual edge detec-
tion
Step 1
Press the menu key.
Step 2
Press the edge soft key.
