Faytech 8 Inch Bedienungsanleitung Seite 48

You can adjust the faytech touch panel calibration with the functions called 4 Points
Calibration, Clear and Calibrate, Linearization and Draw Test. Start by performing the 4
points calibration. By using the application drawing test, you can test the touch panel to
determine if further setting changes are desirable.
When you press the 4 Points Calibration button, the surface of the monitor shows the following
image:
Press blinking X symbol until stop blinking Touch and hold each of the blinking X symbols in
the calibration window until it stops blinking to make sure that the utility can gather enough
data for computation. In addition, a progress bar is shown at the bottom of the window to
indicate time elapsed. If the touch screen is not touched before the progress bar gets to the far
right, the calibration task will be terminated automatically.
The Clear and Calibrate button will clear all calibration and linearization settings. It will then
automatically take you through a 4 Points Calibration.
The Linearization ( 25 or 9 points calibration ) function is used to compensate the touch screen
linearity. It will require you to press and hold on 9 or 25 targets on the screen so it can
compensate for the curvature (if any) of the display. After linearization is completed, the
linearity of the touch screen will be shown in the Linearity curve window.
