In the case of Area Shape = "Ellipse"
1
. Set the coordinates of the center of a circle as
CPX and CPY, and set the radius in the X and Y
directions of a circle as RX and RY.
An inspection area (circle) and the rectangle
circumscribing around it are displayed.
2
. Tilt the ENTER key left/right to set a start point
(SPX, SPY) and an end point (EPX, EPY).
If the coordinates of the start point equal to those of
the end point, all circumference of the circle is
scanned.
Scan direction is always clockwise but
counterclockwise.
3.
Set the size of a cell (W) which is a rectangle
calculating the average brightness.
To change Width-X, tilt the Enter key left/right, to
change Width-Y, tilt it up/down.
4
. Set the number of cells (N).
Settable number of cells: 3 - 3600
Set the number of cells in order to inspect the object
thoroughly from the start point to the end point and
not to overlap cells each other as the figure shown
on the right.
If the cells overlap each other, the checker
repeatedly scans the parts where the cells are
overlapping, resulting in increasing inspection time.
Changed area size by Area Size Adjustment
function does not change the number of cells and
cell size. Specify the number of cells in order to
inspect thoroughly even if an area size will become
larger.
