Assignment of cell numbers
Cell numbers are assigned to the arranged cells from the start point. When a
mask area has been set, it is also possible not to assign a cell number to the
mask area (to skip the cell in the mask area).
1.
Select "Approximate Line Detect Condition".
2.
Select either "Mask Area Include" or "Mask Area Exclude" in "Result
No. Assignment".
Mask Area Include (Default): Assign cell numbers to the cells masked.
Mask Area Exclude: Not assign cell numbers to the cells masked.
The right figure shows an example of the difference in the results of cell
number assignment when the three cells (dotted line) are masked.
Edge Detect Condition
Set conditions of detecting edges of an object.
1.
Select "Edge Detect Condition".
The list of the conditions for detecting edges and the graph is displayed.
When Detect Mode is "Measure Width", two sets of conditions (Condition
0 and Condition 1) are provided. Setting these conditions enables the two
edges to be detected with different conditions to detect the width.
The edges of Line 0 are detected with Condition 0 and the edges of Line 1
is detected with Condition 1.
2.
Set "Scan Direction".
[->]: If the start point is regarded as the position at six o'clock, it scans in
the direction of three o'clock from nine o'clock.
[<-]:If the start point is regarded as the position at six o'clock, it scans in
the direction of nine o'clock from three o'clock.
Selecting the scan direction displays the guide indicating the relation
between the start and end points in the inspection area and the selected
direction on the screen.
