Features:Designed for test the wire circuit state of network cable, telephone cable, such as open, short, cross, etcHigh quality network cable tester suitable for testing both RJ45 Ethernet cables and RJ11 cables.This model adopt automatic scan model, which can rapidly get a test resultThe tester has a detachable section making it perfect for testing cable runs in different locations.RJ45 network cable tester tests double-twisted cables 1, 2, 3, 4, 5, 6, 7, 8 and GroundWith this network cable tester, you can judge wrong connection, short circuit and open circuit.Compact and light weight network cable tester, useful for home and outside use.Specification:Model: WZ-468Detected Cable type: RJ11,RJ45Power supply: 9V laminated battery(Not included)Size: 9.7*10.3*2.8cm/3.8*4.1*1.1inWeight: Approx.116g/4.1ozInstructions:1. Testing double twisted cables 1,2,3,4,5,6,7,8 and G corresponding ,and tell users which exact line is on wrong circuit2. Switch ON is the normal test speed, "S" is the rapid test speed, and OFF is Turn off the Tester3.turn on the tester ,insert the line connector into main tester and remote control .Then the indication lights(1 to 8 and G) will flashMain tester: 1-2-3-4-5-6-7-8-GRemote control tester:1-2-3-4-5-6-7-8-GRJ45 1-2-3-4-5-6------ RJ12 1-2-3-4---------- RJ11)If the connection is not normal, it will be displayed as follows:1.When there is a network cable such as NO. 3 cable is open circuit, the main tester and remote test end NO.3 lights is not on.2.When several cables are open circuit, several cables are not on. When less than two cables are connected, the lights are not on.3.When the two ends of network cables are in disorder, for example, cable 2 and 4 are in disorder, it is shown as follows:Main tester unchanged: 1-2-3-4-5-6-7-8-GRemote tester: 1-4-3-2-5-6-7-8-G4. When there are two wires short circuits , the main tester does not light up, while the remote test end shows that both of the two line lights of short circuit are dim. If there are more than 3 (including 3) short circuits, all the lights of several wires Numbers of short circuit will not light upPackage list:1 x Network Cable Tester (battery not included).
