Testing double twisted cables 1,2,3,4,5,6,7,8 and G corresponding ,and tell users which exact line is on wrong circuit _x000D_ 2. Switch ON is the normal test speed, "S" is the rapid test speed, and OFF is Turn off the Tester _x000D_ 3.turn on the tester ,insert the line connector into main tester and remote control .Then the indication lights(1 to 8 and G) will flash _x000D_ Main tester: 1-2-3-4-5-6-7-8-G _x000D_ Remote control tester:1-2-3-4-5-6-7-8-GRJ45 _x000D_ 1-2-3-4-5-6------ RJ12 _x000D_ 1-2-3-4---------- RJ11) _x000D_ If the connection is not normal, it will be displayed as follows: _x000D_ 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. _x000D_ 2.When several cables are open circuit, several cables are not on. When less than two cables are connected, the lights are not on. _x000D_ 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: _x000D_ Main tester unchanged: 1-2-3-4-5-6-7-8-G _x000D_ Remote tester: 1-4-3-2-5-6-7-8-G _x000D_ 4. 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 up _x000D_ _x000D_ _x000D_ Package list: _x000D_ 1 x Network Cable Tester(Battery not included) _x000D_ _x000D_ _x000D_ Note:_x000D_ Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
