Tinklo kabelio tikrintuvas

Network cable tester.Features:This is a new generation test device that includes analog, digital and PoE (Power over Ethernet) operating modes. Consists of a transmitter, receiver and remote controller. Built-in LED illumination in the transmitter and receiver facilitates work in low light. STP, UTP cable testing: cable length determination; accurate distance to defect determination. For use with IEEE 802.3af /at and non-standard PoE devices. The receiver has a built-in AC / DC voltage meter.Features:Cable Integrity Scan: detects all short circuits, open or crossed wires at both ends, graphically displays results. Cable Length Detection: measures cable/pair length, range: 2.5m ~ 200m. PoE Testing: displays PoE type, voltage, power supply polarity, power mode. Flash function - determines the correct network port based on the frequency of the connected cable (by flashing the tester and hub/router port lights). Network speed and protocol indicators are displayed on the screen.Technical data:Tested cables: (CAT5e/CAT6a/CAT6 categories) STP, UTP.
