Operational Flow
Select the edge detection method.
Select the edge detection method to be used for finding the position of the workpiece.
The default setting at shipment, [Height], is sufficient under normal circumstances. Try selecting
[Reflectance] if edges cannot be detected properly with [Height].
Example 1: Measuring the width of a convex object
Select [Height] to detect the edges with high reliability.
Example 2: Measuring the width of a mountain-shaped object
If [Height] is selected, the measurement result fluctuates depending on the
inclination angle.
The edges may be detected with high reliability by selecting [Reflectance].
