How to Perform Touch Screen Calibration if The Stylus Becomes Irresponsive or Way Off (Inaccurate) to Navigate the GUI?

In the rare case that a VeEX product loses touch screen calibration users could use the Web Remote function to launch the Screen Calibration. Some test sets may offer a special hard key combination to launch the Screen Calibration.

First, check if the Lock Screen icon is being displayed on the top-right corner of the screen, if the test set's touch screen seems frozen or irresponsive, to make sure the touch screen has not been accidentally locked or by another user. VeEX test sets have a dedicated image-png-Dec-13-2022-12-05-00-2081-AM/image-png-Dec-12-2022-11-47-03-7954-PM Lock Screen button, used to prevent accidental interruptions during long-term tests. Press the Lock Screen button to release it and try again.

If the touch screen is responding erratically, besides using the built-in touch screen (which may not be responding correctly) and its graphical user interface (GUI) to launch the Screen Calibration function directly from the test set, VeEX offers two other alternatives to correct stylus-to-cursor offsets, when it is not possible from the touch panel.

Note: Once the touch screen calibration sequence has been started, it must be completed. Accurately touch each of the calibration points with the tip of the stylus.

A. Use Web Remote

If the test set can still be connected to LAN or Wi-Fi, users can just launch a web browser, from a PC, tablet or smartphone, enter the test set's IP address, select Remote Control, enter the password.

Use the PC's mouse to go to >System Tools >Utilities >Settings, click on the touch Screen calibration function to launch it. Then go back to the test set and use its stylus to accurately tap on all the calibration points, with the tip of the stylus.

B. Use Special Hard Button Combinations

Some test platforms offer a button combination to directly launch the calibration feature.
