Area
When a target is located in the measuring area as shown below, the light into the
receiver is partly obstructed, thus creating a shadow.
The contour of the shadow is called “edge.” The area is surrounded by the edge line.
The LS-7000 Series can measure objects with area designation or edge designation.
Area designation is possible in DIA, T-EDGE, or B-EDGE mode. Edge designation is
possible in SEG mode.
