Replacing a HMI, updating firmware, or cleaning the display can shift the touch matrix.
If you are still experiencing issues after following this guide, consult the official for your specific model or reach out to Kunlun Tongda’s technical support team. Happy calibrating!
The latest MCGS models (Tpc7032Gi, Tpc1531Gi) run a Linux kernel. Calibration is handled by the tslib library. There is no visual calibration button in the user runtime.
Clean the screen carefully. Small particles trapped in the edge between the screen and the plastic frame can cause constant "ghost" touches, confusing the system. 2. Cannot Access the Calibration Menu mcgs hmi touch calibration
Maintaining your MCGS HMI can drastically reduce the frequency with which you need to recalibrate it. Follow these best practices to extend the life of your equipment: 1. Keep the Screen Clean
The External Mouse MethodIf the touch is completely unresponsive, plug a standard USB mouse into the HMI’s USB port.
Tap the final confirmation crosshair in the center of the screen.
Only use your fingers or a proper touchscreen stylus. : Place your finger (or a stylus) anywhere
Last updated: 2025. This guide applies to MCGS Embedded, MCGS Pro, and MCGS Utility series HMIs running Windows CE 6.0/7.0 and newer Linux-based models.
For older MCGS units (pre-2018, such as the TPC7062K or TP1062Ti), the operating system does not run Windows CE or Linux. Instead, it runs an embedded proprietary RTOS. On these models, you cannot use OS software tools. You must use the
By following these calibration and maintenance procedures, you can ensure that your MCGS HMI remains a reliable operator tool, minimizing downtime and preventing errors in your automated processes.
However, like any touch-based device, MCGS HMIs can drift over time. A button that used to respond perfectly might suddenly require a firmer press; a numeric keypad might register a "5" when you touched "6." This phenomenon is known as , and it is rectified through a process called touch calibration . Happy calibrating
Calibration is a delicate process. Interrupting it or performing it incorrectly can leave your HMI in an unusable state. Follow these steps before starting:
Less than 30 seconds from start to finish.
