6.4.3 Setting Procedure
1. Proceed up to “Configure the setting for preprocessing” at the third step following section 6.2.1.
2. Set “Area Size Adj.” as necessary.
The “Area Size Adj.” function expands/contracts the inspection area to fit the object (see page 85).
3. Select "Area Size Adj." as necessary.
Select "White" or "Black" from the sub menu.
Tar g et Operation
White Measures the area of the pixels in white.
Black Measures the area of the pixels in black.
4. Select "Filter".
When filtering, select "Dilation" or "Erosion" from the submenu checking the image.
Filter:
Dilates or erodes a cluster of the object image pixels selected at step 3.
Mainly use this function when you delete a slight noise or enhance a detected
area.
5. Select "Position Adj." and press the ENTER key.
(If a position adjustment checker is not created the option “Position Adj.” is
deactivated.) When making a position/rotation adjustment, specify the number
of Position Adjustment checker from the submenu. But, the number of
position/rotation-adjustment-referred checkers must be lower than the number
of the position/rotation-adjustment-referring checker. (See page 140 for
Position Adjustment and 152 for Rotation Adjustment.)
6. Select "OK Judg. Max.".
The value shown next to the right of "OK Judg. Max." is highlighted.
What is OK Judgment Maximum/Minimum value?
These are the standard values of the counted pixels. If the number of counted
pixels is within the range between OK Judgment Maximum and OK Judgment
Minimum, the object will be judged as "OK".
7. Input the setting values for "OK Judg. Max." and "OK Judg. Min.".
If you do not know what standard value you should set to, measure the areas of a good object and a not
good object first and set to the values that a good object can be judged as OK.
8. Press the A key to begin the test.
Check judgment result and area value that appear in the message area of the screen.
If you output the judgment result to the external device, use the "Judgment” function, and if you output the
measurement data, use the "Num. Calcu." function.
