อุปกรณ์ test สาย network line

Tester usage:

Taken with 8 twisted by the root (p) automatic scanning mode, twisted pair and coaxial cable quick test. Just push the power switch to test. And there are two speed test speeds, suitable for different people. The structure is novel, and the handheld end and the remote end can be separated and closed. The use of PVC panels, hidden light-emitting tubes, even if people accidentally step on it will not be damaged, especially suitable for construction site testing. 
Note that this instrument uses a dedicated DC 9V laminated battery, and the battery needs to be equipped separately. 
The dual-purpose multi-function cable tester 
uses automatic scanning, fast test, streamlined shape and ergonomic design. The lines are smooth and simple, anti-drop, and light-proof design, which is more in line with on-site construction. 
Technical indicator 
test cable: RJ11, RJ45 
power supply: DC 9V laminated battery 
power consumption: 25MA 
volume: 10.5*10.5*2.6 mm 
Weight: 200G 

one, function: 

1. Paired twisted pair 1, 2, 3, 4, 5 , 6, 7, 8, G line pairs are tested on a root (pair) basis, and can distinguish which one (pair) is wrong, short circuit and open circuit. 
2. Switch ON is the normal test speed, "S" is the slow test speed, and M is the manual speed. 

Second, twisted pair test: turn on the power, plug the network cable plug into the main tester and remote tester, the host lights flash from 1 to G one by one, the following example: 

main 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, display as follows: 
1. When there is a network cable such as the 3rd line disconnected, the main tester And the remote test terminal No. 3 lighting is not bright.
2. When there are several lines that are not connected, several lines are not bright. When the network line is less than 2 lines, the lights are not bright. 
3. When the two network cables are out of order, the example 2, 4 lines are out of order, the following is displayed: The 

main tester is unchanged: 1-2-3-4-5-6-7-8-G The 
remote test end is: 1- 4-3-2-5-6-7-8-G 

4. When the network cable has 2 short circuits, the main tester display is not bright, and the remote test terminal shows that the two short-circuit lights are slightly bright, if any When more than 3 (including 3) are 
short-circuited, all the short-circuited numbered lights are not lit. 

3. If the patch panel and wall mount module are tested, two matching jumpers (such as 110P4-RJ45) are required to be led to the tester. 

Fourth, coaxial cable test: If the cable is good, the two-end BNC light flashes green at the same time.
