The UNI-T UT681L cable tester tests network and telephone cables with RJ45 and RJ11 connectors. It detects open circuits, short circuits, crossed pairs and incorrect connections, while LED indicators show the status of individual conductors. Tests can be run in fast or slow mode, and the device also checks Ethernet cable shielding.
It is operated with a single button. The automatic power-off function activates after 10 minutes of inactivity, and the low-battery indicator lights up when the voltage falls below 7.2 V.
