Do not rush the process. A precise touch on the target ensures high-accuracy inputs for the entire screen.
The screen registers inputs fine in the center but completely ignores them at the edges.
| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | You tapped too far off-center or used the wrong tool. | Restart the HMI and recalibrate, tapping the exact center of each crosshair. | | Calibration menu won't appear | The touch area for the hidden menu may also be misaligned. | Use a USB mouse. Plug a standard USB mouse into the HMI’s USB port. Use the mouse to click the top-left corner and access the system menu. | | Screen unresponsive after calibration | Calibration data corrupted. The driver cannot map touches. | Perform a hard reset (if a physical reset button exists) or re-flash the firmware. Otherwise, connect a mouse and delete the calibration registry keys (requires advanced WinCE knowledge). | | Only half the screen works | Physical digitizer failure or loose ribbon cable. | Hardware repair needed. Calibration will not fix this. | | Calibration works, but drifts again after 1 hour | Overheating or strong EMI (electromagnetic interference). | Check HMI ventilation and reroute power cables away from signal wires. |
If the touch is so misaligned that you cannot tap the calibration target: mcgs hmi touch calibration
Press precisely in the intersection of the crosshair lines.
before restarting again, or it will stay in calibration mode. 中国工控网 2. Startup Progress Bar Method If you don't want to open the panel to reach the switches: : Watch the screen during the initial boot sequence. Tap Progress Bar
If your MCGS HMI still fails to respond correctly after calibration, the issue might be deeper: Do not rush the process
Turn off the main power supply to the MCGS HMI unit completely. Step 2: Locate the Calibration Trigger
Once inside the TPC System Settings interface, look for the tab labeled "Touch" . Uncheck the "Show Mouse Pointer" option if it interferes, and click the button that says "Touch Screen Calibration" . (Note: If the system is password-protected, you will need the system engineer's credentials to proceed).

If the system has a password set for the system configuration or if the "Blank Hold" method fails, use the .
Power cycle the device. As the system boots up and the MCGS logo or startup screen appears, pay close attention to the display.
