Network Cable Tester

UNI-T UT681C network cable testerUNI-T UT681C cable tester is a handy and reliable tool for checking the condition of Ethernet, telephone and BNC cables. Indispensable in the work of installers, technicians and service technicians, it allows you to instantly detect breaks, short circuits, misconnections or cable crossings. Thanks to its compact design, clear LED indicators and 9V battery power, the UT681C is suitable for both quick tests in the field and thorough network inspections in the office or server room.Multifunctionality that saves timeThe UT681C supports cables terminated with RJ45, RJ11 and BNC connectors (via the RJ45-BNC adapter included in the kit). It allows quick signal continuity checks and diagnosis of short circuits, open circuits and misconnections - including crossed pairs. The built-in LED array (LED1~LED8 and LED_G) allows you to easily assess the condition of individual conductors in the cable, in both fast and slow test modes.Simple operation, maximum mobilityThe device is operated with a single button, eliminating the need for complicated configuration. An automatic shut-off function after 10 minutes of inactivity saves the battery, and a low charge indicator warns when the power supply needs to be replaced. The tester is lightweight, handy and ready to use as soon as the battery is inserted.Robust design for years of useThe UT681C is designed to operate in a wide range of temperatures and humidity, allowing it to be used both in the office and outdoors. CE and UKCA certifications attest to its high build quality and safe use.Included UNI-T UT681C cable tester (transmitter and receiver) 9V battery RJ45-BNC adapter User's manual Manufacturer UNI-T Manufacturer code UT681C Supported connectors RJ45, RJ11, BNC (with RJ45-BNC adapter) Test functions Detection of short circuits, breaks, crossings and incorrect connections Test modes fast, slow Result display LEDs (LED1~LED8, LED_G) Ethernet cable shielding test Yes Power supply 9V battery Automatic shutdown function After 10 minutes of inactivity Low battery indicator Below 7.2V One button operation Yes Operating temperature 0~40°C Storage temperature -10~50°C Operating humidity 20~80% RH Storage Humidity 10~90% RH Maximum operating altitude ≤2000 m Safety standards CE EN61326-1:2013, EN61326-2-2:2013 Net weight transmitter - 87 g, receiver - 51 g Dimensions Transmitter - 102 × 62 × 28 mm; receiver - 102 × 37 × 28 mm Color red-gray
