4.7 Setting Inspection Area and Conditions (Checker)
4.7.1 Types and Overview of Checkers
Checker is a general term of the areas and the conditions for inspecting a captured image.
Sixteen types of checkers are available in the PV500. You can set up to 1000 checkers per product type and
checker type (when the number of used blocks is 10). However, the maximum number of checkers available for
a type is 1000.
The way of counting differs depending on checkers. One checker is not always counted as one. Before you
create a new checker, confirm the number of set checkers displayed on the checker number selecting window.
