Can trace the network cable or Ethernet LAN wire, and diagnose the breakpoint 2. Can trace the cable with RJ11, RJ45, and BNC terminal or other metal wire through the adapter 3. Can directly trace wire when a weak current device is turned on, such as an Ethernet switch, router, and PC terminal 4. Can test the open circuit, short circuit, missing wire, reverse connection 5. Can test the continuity of the cable or wire 6. Can identify the state of the working telephone line (clear, ring, busy) 7. Can judge the TIP or RING line 8. Can test the positive and negative polarity of the DC level 9. Can measure the number of power supply cores of the POE switch 10. Low voltage power supply, save energy, can continue to work below 5V QC Instructions Insert the network cable into the RJ45 interface turn the switch to the alignment /scan the line measurement, and observe the line sequence light. 1. If the connection is correct the indicator lights on both sides of the line scanner, 1-8 lights up in turn (in the case of 8 cores) G light is on when testing shielded wire. 2. When reverse connection, according to the 18 line sequence indicators to judge, for example, the lights on both sides of the line are on as follows 1, 2,3,4,5,6,7,8, G 1, 2,4,3,5,6,7,8, G Then it can be judged that the 3 and 4 wires are reversed, it is consistent with the judgment method of the Network tester. Scanning Instructions Insert the network cable into the RJ45 interface, turn the switch to the scan/start scanning, and the probe is on, it is the target line . The closer to the target cable, the louder the sound of the probe. The switch on the right side of the receiver can adjust the sound level. In a noisy environment. You can wear a headphone to scan. The alligator clip that can be delivered for scanning metal cable connected. The method of telephone line scanning is like the Network line plug the telephone line interface RJ11. Typical Applications Telecommunication network, line engineering and routine maintenance Computer network line engineering Other metal wire wiring works and maintenance work This instrument is suitable for RJ11, RJ45, and other metal wires can be found through the transmitter. the work of the telephone line of the detection of various states, only the transmitter can be detected, such as determining TIP or PING line, to determine the work of the telephone line idle, ringing and off-hook state. the line detection is on the line of the open, shorted, wrong, reverse the physical connection detection.
