Cable Tester For RJ45, RJ12, RJ11& BNC
1. Functions:
1. Can test correspondingly double-twisted cables 1, 2, 3, 4, 5, 6, 7, 8andG, meanwhile can judge wrong connection, short circuit and open circuit.
2. NS-4688tests BNC, RJH and RJ45; NS-468 tests RJ 11and RJ45; NS-468N tests RJ45 and BNC, ST-248 tests RJ45 and BNC, ST-248 tests RJ45 and BNC.
Ii. Test of double-twisted cables; Switch on the power. (s is slow and remote tester. The lights of the main tester will turn on.
Sequently from 1 to G.
Main tester: 1-2-3-4-5-6-7-8-G
Remote tester: 1-4-3-2-5-6-7-8-G
Following are abnormal connections:
1. If one cable, for example cable NO. 3is open circuited, the two NO. 3lights of the main tseter and remote tester will not turn on.
2. If several cables are not connected, several lights will not turn on respectively. If less than two cables are conntected, none of the lights is on.
3. If two ends of a cable is disordered, for example NO. 2andNO. 4, then displays on:
Main tester: 1-2-3-4-5-6-7-8-G
Remote tester: 1-4-3-2-5-6-7-8-G
4. If two cables are short circuited, neither of the corresponding lights ison of the remote tester while main tester remains unchanged. If three cables, including three, are short circuited, none of the corresponding liaghts is on.
Iii. If test patch panels or wall plate outlels, two cables which can match each other(eg110 P4 and RJ45)will be connected to the tester.
Iv. If test cables of the same axes, BNC turns on when the cable works.
BNC RJ45 RJ11 RJ12 multi network cable tester
Test by cables of the Same BNC Axes:
1.Put one end of the cable into both main tester and BNC socket,and put the other into the
remote tester.
2.Switchin the power,which works if the light is on.
3.BNC light will not be on when the cable is connected.Any flash of the light means an
improper cable is connected.
4.Press the button on the left of the main tester.If the light is green,the cable works;if
not(means red or any othercolor of light),the cable is out of work.
Test by Twin-twisted Cables:
1.Put one end of the cable into the main tester.
2.Switch on the power,which works if the light flashed.
3.Once switched on,LEDS of the remote tester will scan the cable accordingly.If the cables
are good,the corresponding LEDS will turn green sequently.If the cables are outof work,the
LEDS will first turn green then red or other others,or the LEDS will not be on or be on
disorderly.
4.If the cables are shielded,shieldingis tested when GND is turned on.If shielding is
normal,the corresponding LEDS and GND will turn green.If not ,the LEDS will first become
green then ted or will not be on at all.
Attention:
1.Twin-end:can test cables of the same BNC axes and double-twisted cables.
2.Single-end:the two ends of one cable can be connected to the main tester for test for test if remote tester is not applied.
3.when test is done by both main tester,only connectin or open circuit can be seen from the main tester while opposite connection or short circuit is displayed by the remote tester.Red light means opposite connection and non-light means open circuit.Whentest is done by main tester exclusively,only connectin of the cables can be seen while opposite connection cannot.
