Portable SC8108 RJ45 Meter Cable Tester: Efficient, efficient, reliable, compact, lightweight, easy to carry and use. Large LCD screen to show test results, with long battery life (standby mode or standby for more than 50 hours).Easy to Use: Auto-timer is disabled. Comes with 1 passive far end test socket. Remote recognition system with fast voice. One person is enough to perform the Cable Continuity Check and Cable Sequence.97% Accurate Measurement: Measure length and pair with or without remote identifier. Measures cable length and determines open circuit and short circuit distance. Dynamically calibrates cable length and performs length measurement as accurate as 97%.Multiple Errors Can Be Checked: Allows you to check wiring errors in 5E/6E twisted cord network, coaxial cable and telephone line.Widely Used: Applicable for open circuit, short circuit, flying lead, reverse connection or crosstalk interference.Product Features: The tester automatically detects the cable from the remote matcher (ID) or local port (L) and displays if the end of the cable to be tested does notdoes not fit into the remote matcher (ID ) or if the cable does not fit into the local port (L) when testing locally. Test results are displayed digitally via its LCD screen and it instantly displays the exact cable configuration.It performs a line test without requiring the external adapter.Tester cable type: STP/UTP twin twisted cable, coaxial cable, telephone line Tester port: RJ45 master port of tester (M), RJ45 port (L) LOOPBACK of tester, RJ45 port of remote end recognition device (R)(BNC and RJ11 converters (not included in the kit), can be used to measure and check the continuity of coaxial cable and telephone line) Double twisted cable length measurement: Range: Calibration 1-350 M (3-1,200 FT) Calibration accuracy: 3% (0.5 m) (calibration cable 5 M) Sending Accuracy: 5% (AMP, ATT Class 5 Cable) Unit of measurement: Display in meter (M) or feet (FT) Length calibration: User can set auto-calibration factor with given length cable. The length of the calibration cable is more than 5M Wiring sequence and cable location error: Check for errors such as open circuit, short circuit, reverse connection, crosstalk or crosstalk interference Locating cable: Included 1 passive test jack for far end Auto power off delay: the tester is idle for 30 minutes Powered by: 4*1.5V AAA batteries (not included) Package: 1 * Multi-Network Cable Tester1 * Far-End Test Socket 1 * Instruction Manual
