It might additionally assist detect defective cables if used with a USB-C gender changer.

With this slipped into the again of the probe you’ll be able to then insert the machine into any USB-C port you need to test. A small quantity of present is handed into every USB C pad by way of an LED and a current-limiting resistor. If there’s completely nothing related to a selected pin then an LED merely gained’t gentle. A grounded pin will trigger the LED to be brightly lit and if a pad is related to different circuitry then the LED will shine usually. Don’t fear if that sounds somewhat complicated as there are quite a few photos of examples over on the product web page. As a further diagnostic software, after having run the probe and detected any points, you’ll be able to take away the battery and use a digital multimeter to discover any recognized points by probing the contact factors, basically utilizing this machine as a USB-C breakout board.
