Chapter 6: Touch Screen Calibration Utility 6-11
3. Test the calibration on the draw screen.
Touch the screen in various spots and trace each of the horizontal and vertical
lines, including the border around the screen.
In this test, all touches are persistent, including touch downs (green dots) and
touch ups (red dots).
After tracing the lines, review the drawn lines to make sure they closely follow the
underlying pattern. Pay close attention to the edges of the display and the corners
since this is where an incorrect calibration is most noticeable. If a line or point
appears to be outside the pattern, try pressing the area to see how far the cursor is
from the touch point. If the registered touch is greater than 7 mm away from
where the touch occurred, repeat the calibration.

if you are satisfied with the results and want to close the application.
