1、If the user is using capacitive touch screen, it is recommended that the user should first install the driver required for capacitive touch screen according to the relevant manual, and then click "Start" / "Program" / "Microtouch Touchware" on the screen in order to run the screen calibration program. "/" Microtouch Touchware "to run the screen calibration program, calibration is complete, the system will automatically store the calibration data in the controller's registers, later restart the system without the need to calibrate the screen.
2、If you operate the capacitive touch screen in the middle, change the touch screen monitor resolution or display mode again, or adjust the refresh frequency of the touch screen controller by yourself, and feel that the cursor and touch point cannot correspond, you must re-calibrate the touch screen system.
3, in order to ensure the normal work of the touch screen system, in addition to ensure the correct installation of the system software, you must also remember not to install two or more touch screen drivers on a host, which will easily lead to conflicts in the operation of the system, so that the touch screen system can not be used properly.
4, in the use of resistive touch screen, if you find that the cursor does not move or can only move in the local area, the user can check whether the touch screen touch area is always pressed by other touch objects, for example, once the touch screen is pressed by the display housing or cabinet housing, it is equivalent to a point has been touched, then the feedback to the controller's coordinate position is not accurate.
5, as mentioned earlier, once the system in the replacement of the display resolution, adjust the screen size and the first installation are inaccurate click or drift, you need to start the application comes with the positioning program repositioning, but in positioning, it is best to use a relatively fine pen or fingertip for positioning, so more accurate.
6, surface acoustic wave touch screen working environment requirements are high, it must require work in a clean, dust-free environment, and also regularly clean the touch screen surface dust, otherwise, the dust in the air covered in the touch screen around the reflective stripe or transducer, it will affect the correct positioning of the system.
7, do not let the touch screen surface with water droplets or other soft things stick to the surface, otherwise the touch screen is easy to mistakenly think that there is a hand touch caused by the surface acoustic wave screen is not allowed. In addition in the removal of dirt on the surface of the touch screen, users can use a soft dry cloth or detergent carefully wipe from the center of the screen outward, or use a dry soft cloth dipped in industrial alcohol or glass cleaning solution to clean the surface of the touch screen.
8, if the hand or other touch objects to touch the surface acoustic wave touch screen, the touch screen response is very sluggish, which means that it is likely that the touch screen system is old, the internal clock frequency is too low, or because the touch screen surface is moving water beads, to restore the touch screen fast response, you must replace or upgrade the system, or wipe the surface of the touch screen with a cloth to dry the water beads.
9, touch screen generally use the serial port for signal transmission, take the signal from the PS / 2 port, while the TPS screen is directly from the host power supply. If the indicator light does not light up, indicating that no signal is taken, the PS / 2 line on the control box may be bad. If the light is on, but still does not flash, the control box is bad, so users must replace the control box. If the replacement control box or not, it is possible that the screen is pressed too tightly, you need to loosen the screws around a little, because the touch screen is composed of special materials, it is not easy to damage the body. If the serial port is bad or disabled, it will cause the driver can not be installed, because when the driver is installed, it will automatically look for the serial port. Even if it can be installed, the mouse will not move or cannot be positioned. It is best not to use the serial mouse to determine whether the serial port is good or bad, it is possible that the serial port 9 root for them each in a different way. If the screen is pressed, or the ground wire is not connected, it will lead to the inability to position. If there are some areas can not click or slow response, it is possible that the impact of dust, need to remove the shell to remove the dust.
10, when touching the capacitive touch screen with a finger at a certain location, the touch screen does not have any response, which is likely to be inaccurate for that touch bit, the cursor, of course, can not be correctly positioned. If the cabinet shell pressed touch area users can adjust the distance between the cabinet and the monitor screen, if the monitor shell pressed touch area, users can try to loosen the monitor shell screws a little to try.
