19.4.2 Touch Calibration in Xpanel

You can also start the touch calibration in the Xpanel device. There are three methods to start the calibration.

(1) Unable to open [Xpanel Config]

If the touchpoints are excessively mislocated and there is an inability to use a mouse, you can press and hold a random point on the screen for 30 seconds (default) to start the touch calibration. Follow the instructions and reboot the Xpanel device after the calibration.

To alter this option, the ‘Hold time(sec) for Touch Calibration’ option must be configured. Press the [Configure] button on the ‘Ethernet Loader’ window to open the ‘Configure’ window.

(2) Touch Calibration in [Xpanel Config]

You can start the touch calibration by pressing the [Touch Calibrate] button in the ‘Xpanel Config’ window. To bring up the ‘Xpanel Config’ window, press the corners of the Xpanel screen as shown below (Bottom Left → Bottom Right → Top Right).

Press the [Touch Calibrate] button to start the calibration. After the calibration, reboot the Xpanel device to save the calibration settings.

In the case of the Xpanel models such as XT10/12CB, you can select the calibration mode. There is a 4, 9, and 16 point mode. For more accurate calibration, select ‘16 Points’ mode.
