Appendix B:
Touchscreen Calibration
Only units with resistive touchscreens need to be calibrated. PCap displays do not
require calibration.
Proper Touchscreen Methods
Before performing the calibration procedure please observe the following guidelines for
proper/improper methods of touching the screen.
• Face the monitor directly.
• Perform the calibration in the position (sitting or standing) that you normally expect
to use the touchscreen.
• Touch the calibration target firmly and precisely with your fingertip. During
calibration, be careful to keep your fingernails and other fingers away from the
touchscreen as you touch each target.
• The hand and calibration finger should be perpendicular (straight up) from the
touchscreen during touch down and removal of the calibration finger. Keep the
other fingers closed and away from the touch-screen.
