Basic Setting Procedure

■ Teaching
The area to be inspected needs to be enclosed by a rectangular box, then teach it. The
selected image in the area is registered as the inspection reference (model).
Measurement is unstable when there are two or more of the same pattern. Register
unique pattern in the screen or restrict the search range.
Application and Setting Examples p.152
■ Adjusting the threshold level
Threshold values are adjusted to determine the range for OK judgment. Adjust the
threshold values referring to the current indicated measurement results. Adjustment of
the threshold values must be done in ADJ mode.
