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. Continuity Test: Emitter, Minimum recognition length of 10cm; Receiver, Minimum recognition length of 1m Short Circuit Detection: Supports network cable short circuit detection. Length Measurement: Measures open/ short-circuited network cables from 1 to 600 meters. Accuracy: Cable length x 3% ± 1m PoE Testing: Supports IEEE802.3BT/AT/AF and non-standard protocol detection. Displays power supply voltage, power supply pins, and pin polarity. Supports PoE input voltage loop-through output. Real-time power can be detected when connected to a load. Online power range, 0-90W. PD Power Detection: Detects standard or non-standard PoE, supports 24V and 48V PoE. PSE IN and OUT: Measure the PSE power supply voltage and power. Emitter: 3.7V 2000mAh lithium-ion rechargeable battery; Receiver: 3.7V 2000mAh lithium-ion rechargeable battery Application:The multifunction Cable tester is designed for maintenance and installation of cable, cable tracer, optical power meter and Visual fault locator test in one equipment. The unit supports detect the near-end, mid-end and far-end fault point of RJ45 cable connector, and also supports PoE power supply protocol, measure the PSE power supply voltage and power. Installers and engineers take the all in one cable tester, making working conditions safer and increasing productivity.
