Ensuring Precision: A Guide to Touch Calibration on MCGS HMIs

Mcgs (Configuration Software) HMIs, produced by Beijing Kunlun Tongtai, are widely used in industrial automation for their stability and ease of use. However, like all resistive touch screens (common in many MCGS models), they can drift over time due to aging, temperature changes, or physical impact. When your button presses no longer match the intended input, it’s time for a touch calibration.

If the touch screen is not calibrated correctly, it can lead to incorrect or inconsistent responses, causing errors and downtime in the production process. mcgs hmi touch calibration

When Do You Need to Calibrate?

• The cursor responds but is offset from your finger/stylus.
• Pressing a button activates an adjacent button.
• The screen does not register touches in certain areas.
• After firmware updates or battery replacement (for systems with RTC backup).

Accuracy: For the best results, use a plastic stylus with a tip radius of at least 1 mm to avoid damaging the resistive screen while ensuring precise target hits. The cursor responds but is offset from your finger/stylus
