Complete Guide to MCGS HMI Touch Calibration: Restore Screen Accuracy
对于基于Windows CE的MCGS TPC设备，进入CE操作系统桌面后， 双击"触摸屏校准"图标 ，即可启动校准向导。
This action often forces the HMI into the factory calibration utility. 4. Tips for Accurate Calibration If persists, replace overlay | : Ensure your
If you are using an touch screen, you are working with a powerful, versatile, and widely trusted industrial platform. However, even the most robust industrial touchscreens require occasional maintenance.
Physical damage to the resistive overlay or a loose internal ribbon cable.
If specific corners refuse to register your touch during calibration, the outer resistive glass layer may be cracked or worn out from repetitive use. The digitizer panel needs to be replaced. 3. Settings Aren't Saving After Reboot you are working with a powerful
Drag and drop a new standard button onto your "System Maintenance" or "Settings" window.
Code: !CalibrateTouch() (Note: Exact syntax can vary slightly between MCGS basic and MCGS Pro versions; check your software's system function library under "Screen/Touch control").
