NOTE: Your touch screen is configured and calibrated at the factory. However, if you notice that the
calibration is not as precise as you would like, you can use the 4 Points Calibration and/or the
Linearization tool to provide a more accurate alignment of the touch screen.
• Graph of the Linearization Curve of the touch screen – for reference and troubleshooting
purposes. See its usage in the discussion of the Linearization function.
• 4 Points Calibration – Calibration aligns the touch panel with the video screen. The touch
screen must be calibrated to allow for positional accuracy of the stylus or finger touch inputs.
• Clear and Calibrate – Clears the calibration/linearization parameters and allows you to
perform the 4 points calibration again.
• Linearization (9 or 25 points linearization is set within the
function provides for more precise mapping of the stylus or finger touch inputs. After
linearization is completed, the linearity of the touch screen will be shown in the Linearization
Curve window.
• Draw Test - used for accuracy and performance checking.
