How to use the network cable detector and how to use the network cable detector

1.Line Status Test:

Insert one end of the alligator clip adapter cable into the RJ-11 socket of the transmitter, and clamp the red and black wire clamp at the other end of the adapter cable to the line to be tested.

2.Line DC level detection and positive and negative polarity determination

Flip the transmitter's function selector switch to the SCAN position and clip the red and black clips to the line. If the status light is red or green, it means there is a DC level in the line. If the green light is on, the red clamp is the positive pole, and the black wire clamp is the negative pole; If the red light is on, the black clamp is the positive pole and the red clamp is the negative pole.

The level can be determined by the brightness of the status indicator: the brighter the lamp, the higher the level; The dimmer the light, the lower the level.

3.Bell Signal Detection:

Toggle the transmitter's function selector to the off position and clip the red and black clips onto the line. When a bell signal enters, the status indication flashes red and green alternately. If there is a DC level in the line at the same time, the status indicator flashes red and green on top of red or green.

4.Direct Adaptation:

When hunting, if the user line end is an RJ-11 plug, the plug can be directly inserted into the RJ-11 socket of the transmitter, and when the wire is matched, if the user line end is an RJ-11 or RJ-45 plug, the plug can be directly inserted into the transmitter or connected.

receiver on the RJ-45 socket.

Just connect one and the other hunt will make a screeching sound if it is the same.

Here's how to use it:

Plug the crystal heads at both ends of the network cable into the RJ45 ports of the main tester and the remote test end respectively, and turn the switch to "ON" (S is the slow gear), then the indicator heads of the main tester and the remote test end should be flashed one by one.

1. Straight-through connection test: When testing the straight-through connection, the indicator light of the main tester should flash in order from 1 to 8, and the indicator light of the remote test end should also flash in order from 1 to 8. If this is the case, it means that the connectivity of the through line is fine, otherwise it will have to be redone.

2. Staggered line test: When testing staggered wire, the indicator light of the main tester should also flash in order from 1 to 8, and the indicator light of the remote test end should be flashed one by one in the order. If so, the staggered connectivity is fine, otherwise it will have to be redone.

3. If the line sequence of the land car at both ends of the network cable is incorrect, the indicator light of the main tester will still flash one by one from 1 to 8, but the indicator light of the remote test end will flash one by one according to the order of the line number connected with the main test end. That is, the remote test side cannot be shiny in the order of (1) and (2).

4. The phenomenon of wire open circuit test.

When 1 to 6 wires are broken, the indicators of the corresponding wire number of the main tester and the remote test end are not lit, and the other lights can still be flashed one by one.

When 7 or 8 wires are broken, the indicators on both the main tester and the remote test end are not illuminated.

5. The phenomenon of wire short circuit test is stupid.

When there is a short circuit of two wires, the indicators of the main tester will still flash one by one in order from 1 to 8, while the indicators corresponding to the two short circuits at the remote test end will be lit at the same time, and the other indicators will still flash one by one in the normal order.

Obimori When there are three or more wires shorted, the main tester's indicator lights still flash in order from 1 to 8, while the corresponding indicators for all short lines at the remote test end are not illuminated.

When using the network cable detector, follow the steps below.

Operation steps: 1: First turn on the power of the network cable detector and check whether there is power.

2: When the network cable detector is measuring, the power switch is turned off first, and the two ends of a network cable need to be connected to the network cable interface of the tester host at one end, and the other end is connected to the network cable interface of the tester auxiliary machine. Then turn on the power on the main unit and test the display condition of the light.

The access method is as follows: 3: Carefully observe the numbers on the two rows of display lights of the host and the auxiliary machine, whether they are symmetrically displayed at the same time, if the symmetrical display, it means that the network cable is good, if the asymmetrical display or individual lights are not on, it means that the network cable is disconnected or the wire core is arranged incorrectly when making the network cable head.

Note: When the network cable is inserted into the detector, the dirt and rust stains on the metal contacts of the crystal head should be cleaned first, and then inserted into the access port.

The network cable tester, that is, the network cable tester, can test the twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G line one by one (pair), and can distinguish which one (right) is wrong, short circuit and open circuit.

1. There is a device such as a switch or router at the other end of the network cable plugged in at the female end, and the indicator light of the female end should be lit from 1 to 8 in turn, which means that the network cable is fine, and the connection between the network cable and the device at the other end is normal.

2. The other end of the network cable plugged in by the female end is not connected to any equipment and the child end, at this time, the indicator light of the female end should not have any response, and there is no device on the opposite side, so the connection has no meaning.

3. Another end of the network cable plugged in by the female end is connected to the sub-end, the situation is the same as 1, the normal situation is that the 8 indicators are lit in turn, but if there is a problem with the network cable, the indicator will be partially lit, indicating that there is a problem with the network cable.

1. It is necessary to insert the straight line or cross wire into these two interfaces respectively.

2. Then turn on the switch here.

3. An important step to judge whether the network cable is connected, carefully check the synchronization of the two network cable lights, and note that it is the "synchronization" lighting order.

1) If it is a straight line, the order of the two sides in turn and synchronous lighting is , virtual rock potato;

2) If it is a cross line, the order of the two sides is sequential and synchronous;

3) If there is a light that does not turn on or the order is not in the right order, the network cable is not connected and needs to be remade.

The network cable tester can test the twisted pair 1, 2, 3, 4, 5, 6, 7, 8, G line one by one (pair), and can distinguish and determine which one (to the jujube infiltration) wrong wire, short circuit poor and open circuit. The RJ45 head copper plate cannot be tested when it is not completely depressed, otherwise the port will be permanently damaged; Please use original quality crimping tools and crystal heads; Ports that do not indicate RJ11 cannot be tested** to connect to RJ11, otherwise the port pins will be permanently damaged.

Turn on the power switch of the line tester, plug in the network cable, if it is 1 2 3 6 line light, it means that the network cable is good, if not, it means that the network cable is not through, check whether the line sequence of the network cable and the metal sheet of the network cable and the crystal head are connected. The network cable sequence of T-568B is: white orange, orange, white green, blue, white blue, green, white brown, and brown T-568A's network cable sequence is to reverse the 1 3 2 6 of 568B.

Do you mean a wire finder?

The big head is connected to the A head of the network, open the scanning, the small head has a multi-line scan on the other side, and when it encounters the corresponding line of the A head, the small head will send out a beeping prompt!

Identify the target cable among the many cables.

Plug the line in and see if the lights are on one by one, and the problem is even greater.

Is it the one that has too many wires to find the wire, or the one that the test network cable can't get through?
