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.
