• Adjust the Intensity Range.
Intensity Range is the range of grayscale values the sensor should look for. To set the Intensity Range, use
the eye dropper to select the target feature. Use the slider to fine tune the selection. As the slider is moved,
green highlighted areas indicate the objects the sensor finds.

• Adjust the Area Range.
Use Area Range to set the size limits of a feature of interest. Move the slider to select the range. Areas are
measured by counting pixels. For example, a rectangular feature that is 100 pixels wide by 200 pixels tall
has an area of roughly 20,000 pixels.
(p. 82) indicates that the areas that are white are now within range of the inspection. As the
range narrows, the highlighted area turns yellow. In the Demo example, the Area Range is adjusted so that
each letter is identified as a found object (indicated by the red highlight and the blue +).
