3.4.2 Touch calibration
Calibration process is running automatically based on the resolution. If the screen is not calibrated,
the active area or the touch screen may not be aligned properly or may be unnecessarily small in
size. Therefore, you need to calibrate as the following picture. Once calibrated, the information of
calibration is saved by the touch screen for each video solution. So, you do not need to calibrate
any more.
However, you need to calibrate when you change a PC. For more accuracy, follow the below
instruction and also refer to the
3.4.4 Fine coordinate Correction - offset
and
3.4.5 Fine
coordinate Correction – zoom.
3.4.2.1 Calibration
1. As you click the [Calibration], the circle targets appear on the screen.
2. Position your finger or pen to the center of the circle.
3. Repeat for additional calibration targets.
4. If you accidentally touched the screen in the wrong place during the calibration, you will distort
the touch screen calibration. Test to make sure you are satisfied with the calibration results.
3.4.2.2 Auto Calibration
As you click the [Auto Calibration], calibration process is running automatically based on the
resolution. This mode is possible to make a touch when the size of touch screen is only same as
the size of panel.
