High quality cable tester for utp/stp ri45  bnc cable tester

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.
