This area is displayed in the form of a rectangular box on the vision screen.
Offset X / Offset Y
When indicating the distance from the cross hair center of the vision screen to the
center of this rectangular box, i.e. test box in the Right-Down Coordinate System,
the distance in the X-axis direction is called Offset X and the distance in the Y-
axis direction is called Offset Y.
Count X / Count Y
The size of the test box in the X-axis direction is called Count X, and the size of
the test box in the Y-axis direction is called Count Y.
When activating the <Test> button, the Offset / Count cell must be clicked.

<Test> button
Sets the nozzle recognition condition and lighting condition by testing the binary
value of the pixel for the certain area (test box) that is set using the fly camera.
When the binary value of the pixel for the area that is used to check whether the
nozzle is mounted or not is below 30%, the nozzle is considered to be mounted. If the
value is above 30%, the nozzle is not considered to be mounted.
