Tool Property Page
Calibration, draw test tools and the linearity curve of the touchscreen were list in this property page shown as
below for user to do touchscreen calibration and touch position test.
User can do calibration or draw test by pressing the function push buttons.
1. Linearization Curve
Linearization curve of the touchscreen is list in this page for reference and trouble shooting purpose.
2. 4 points calibration
It needs calibration before the touchscreen can work accurately. Whenever the user feel the accuracy lost,
user can do calibration again to get a more accuracy touch function.
Pressing this button, a new window will be popped-up at the location when the touchscreen was mapped to
area for this touch system to guide the user do 4 points calibration.
User should follows the guide to touch and hold the blinking X symbol in the calibration window until it does
not blink to make sure that the utility can gather enough data for computation. In addition, a time line bar is
shown in the bottom of the window to indicate time elapsed. If the touchscreen was not touched before the
time line bar going to right end, the calibration task will be terminated automatically.

Caution :
■ At the fi rst assembly of touch screen, we suggest applying 25 points calibration.
■ For a more accurate calibration of touch screen, please apply 25 points calibration.
3. Clear and Calibration
Press this button to erase the 25 points calibration/linearization parameters and force user to do 4 points calibration again. After 25 points calibration data was clear, the 4 points calibration data will be invalid. It needs to
do 4 points calibration.
4. Linearization
Linearization ( 25 or 9 points calibration ) function is used to compensate the touchscreen linearity. After linearization completed, the linearity of the touchscreen will be shown in the Linearity curve window.
Pressing this button, a new window will be popped-up at the location when the touchscreen was mapped to
area for this touch system to guide the user do 25 points calibration. User should follows the guide to touch
and hold the blinking X symbol in the calibration window until it does not blink to make sure that the utility can
gather enough data for computation. In addition, a time line bar is shown in the bottom of the window to indicate time elapsed. If the touchscreen was not touched before the time line bar going to right end, the calibration task will be terminated automatically.
5. Draw Test
This function is used for accuracy and performance check. Press this button and a new pop up window will be
popped up in the location where the touchscreen was mapped to the touch system as below,
User can press the Clear button to clear the window. Press Quit button to terminate this draw test.

2.1 FAQ Chapter 2
1. Must calibration be down after installation completed?
After connecting your touch monitor and installing the software, you must calibrate the touchscreen. Calibration serves two
purposes:
(A) Set the active area of the touchscreen.
(B) Align the touchscreen’s active area to the underlying video.
2. The touchscreen is not accurate
Calibration should be required.
Make sure to touch the centre of each X once at a time.
3. The touchscreen is accurate in most areas, but off a lot in certain area
The touchscreen may have linearity problems. Please use touch screen and select more points calibration.
4. Why can the display not match to the touchscreen correctly after calibration?
The touchscreen will be aged after a certain period of consumption or under harsh environment. It is normal.
The touchscreen driver has an utility to adjust the situation. The calibration point can be more on the touch
screen.
