Start-up

Calibrating the touch screen

Linearisation is used for calibration. For performing linearisation, the application 
"eGalaxTouch" is installed on the system. The application can be started via an icon 
on the desktop interface.



Stand directly in front of the device.



Start "eGalax Touch" application.



Select tab "(die) Einstellung".



Ensure that in the section "Linearisierung Art" the setting "25-Punkte" has been 

selected.

Performing linearisation



Under the tab "(die) Werkzeuge" click on the button "Linearisierung".
The screen appears as a white surface. Red cross hairs are shown in the lower left 

corner.



Press and hold the middle of the cross hairs using the index finger.
The message "OK!" appears after approximately three seconds.
24 further cross hairs appear.



Repeat the process.

Performing graphics test

The quality of the linearisation can be tested with a graphics program.



Under the tab "(die) Werkzeuge" click on the button "Zeichen-Test".
A grid is displayed on the screen.



Try to hit the points of intersection on the grid using the index finger.
Small red crosses are shown at the touched positions.

If the quality is insufficient, linearisation can be repeated.

Note

The touch screen must be calibrated for the cursor to follow the motion of the 

finger exactly. Calibration is required in the following cases:

−

The device has been newly mounted.

−

Modifications have been made to the device.

All installation work must be complete in order to perform calibration. When the 
design frame has been mounted, the touch screen cannot be calibrated until a 
waiting time of 5 minutes has elapsed.
