Secondary code digital mode, decisively rejects noise and false signals, locate cables quickly and easily. Advanced UTP cable test, test UTP cable's sequence, type and remote kit, quickly detect the near-end, mid-end and far-end fault point of RJ45 cable connector. RJ45 cable TDR test, test cable's length, measurement range 600 meter. Port Flash, can search the switch port which connect the meter, and detect the connected network port (100/ 1000M). PSE IN and OUT, measure the PSE power supply voltage and power. Cable tracer, can search UTP cable, BNC cable from mess cable PoE detector, support IEEE802.3af/at/bt supply power protocol, measure the PSE power supply voltage Cable Length, max 600m UTP cable test, test cable's sequence, type and remote kit Network cable short-circuit test and the fault point of RJ45 cable connector Feature Secondary code digital mode, decisively rejects noise and false signals, locate cables quickly and easily.
