Packaging and accessories: carton, leather bag, host, accessory, manual Test cable: RJ45 twisted pair, telephone line Power supply: DC 9V laminated battery Power consumption: 25 MA Volume: 10*9.5*2.7mm Weight: 200G 2. Function: 1. Test twisted pair wire pairs 1, 2, 3, 4, 5, 6, 7, 8 and G one by one (pairs) and can distinguish which one (pair) is wrong, shorted or open. -circuited. 2. The ON switch is the normal test speed, "S" is the slow test speed, and M is the manual speed. , Twisted pair test: turn on the power, insert the network cable plugs in the main tester and remote tester respectively, the main unit LEDs will flash one by one from 1 to G as shown in the following illustration: Master tester: 1-2-3-4-5-6-7-8-G Remote tester: 1-2-3-4-5-6-7-8-G (RJ45) 1-2-3-4-5-6------(RJ12) 1-2-3-4---------- (RJ11) If the wiring is not normal, it will be displayed according to the following conditions: 1. When a network cable such as #3 is disconnected, the #3 LEDs on the main tester and the remote test end will not light up. 2. When multiple wires are disconnected, multiple wires will not light up. When network wires are connected to less than 2 wires, the lights will not light up. 3. When both network cables are out of service, for example 2, the 4th line is out of service, the display is as follows: Main tester unchanged: 1-2-3-4-5-6-7-8-G The remote test terminal is: 1-4-3-2-5-6-7-8-G 4. When two network cables are shorted, the main tester does not light up, while the remote tester shows that the lights of the two shorted lines are dimly lit. If there are more than 3 (including 3 ) When there is a short circuit, the lights of all the short circuit numbers are off. 4. If the splitter and the wall module are tested, two matching jumpers (such as 110P4-RJ45) are required to lead to the tester. 5. Coaxial cable test: if the cable is good, the BNC lights at both ends flash green at the same time Note: the data is manual measurement, please allow an error of 1- 43cm, due to differences between light and screen, there will be a certain color difference, the specific received in kind prevail.
