1. 4 points calibration
The device needs to be calibrated for the touch screen to work accurately. Whenever the
touch screen seems inaccurate, recalibrate the screen again.
Press this button to display a new window to guide you to do the 4 points calibration.
On the calibration window, follow the guide and touch and hold the blinking symbol as it
moves around the screen. The calibration process is complete when “OK” is shown.
2. Clear and Calibrate
Press this button to erase the 25 points calibration data and recalibrate the screen using the
4 points calibration. After the 25 points calibration data is cleared, the 4 points calibration
data also becomes invalid. Therefore, the 4 points calibration must be done.
3. Linearization
Linearization (25 or 9 points calibration) function is used to compensate the touch screen
linearity. After linearization is complete, the linearity of the touch screen is shown in the
Linearity curve window.
Press this button to display a new window to guide you to do the 25 points calibration.
On the calibration window, follow the guide and touch and hold the blinking symbol as it
moves around the screen. The calibration process is complete when “OK” is shown.
