Setting Judgement Limits
Set a tolerance (Maximum and Minimum values) of area or gray average measured in each cell.
If the detected data are within the tolerance, the object will be judged as "OK", if they are outside of it, the object
will be judged as "NG". When judgments of all cells are "OK", judgement of the checker will be "OK".
The maximum/minimum value can be set in two ways, common setting and individual setting. The common
setting sets the same value for all cells and the individual setting sets separate values. When you want to set
criteria for OK judgement by cells, use individual setting.
1.
Select "Judgement Limits".
2.
Press the TRIG key to execute a test.
The area of each cell is displayed for your guide to set
maximum/minimum values.
3.
To set values individually, select "Yes" for "Set
individually".
Select "No" not to employ Individual Setting.
4.
Select the table of maximum/minimum values.
5.
To employ the common setting, select the row of "Common" and enter a value.
To use the individual setting, select a cell number and enter a value.
After the setting is completed, press the CANCEL key.
Running a Test and Confirming Result

1.
Press the TRIG key.
When a live image is displayed on the screen, PV captures a new image first and runs a test. When a
memory image is displayed, it runs a test using the current memory image without capturing any images.
Position adjustment is also executed at the same time if it is used.
