Step5: Enter values in Upper fi eld and Lower fi eld.
NOTE
Standard values are 80 (Upper) and 0 (Lower).
NOTE
OKNGImages can register different images for OK and NG images and judge an
image is OK according to the setting. To set the algorithm to judge an image is OK
if the matching rate with the OK image is high, set Upper to around 100 and Lower
to around 70. To set the algorithm to judge an image is OK if the matching rate with
NG image is high, set Upper to around -70 and Lower to around -100.
Step6: Enter the appropriate vector into the Shift fi eld. Any value from V1 to V8 is available.
Select the vector according to the Memorize to fi eld of the Adjust window.
Step7: Press Inspect. Make sure that the inspection is completed properly.

Memorize to -
Upper, Lower
Enter the number of characters to Upper fi eld and Lower fi eld.
The sample value shows the number of recognized characters.
If the registered characters and the recognized characters are matched, the result will be OK.
