Functions :
»
Can test correspondingly double-twisted cables1, 2, 3, 4, 5, 6, 7, 8 and G, meanwhile, can judge wrong connection, short circuit and open circuit. NS-468B tests BNC, RJH and RJ45; NS-468 tests RJ11 and RJ45; NS-468N tests RJ45 and BNC; ST-248 tests RJ45 and BNC
Test of double-twisted cables :
»
Switch on the power. (S is slow automatic grade, M is manual.) Put cables into both main tester and remote tester. The lights of the main tester will turn on sequentially from 1 to G.
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
»
-2-3-4-5------------ RJ11
Following are erroneous connections :
»
If one cable, for example, cable No. 3 is open circuited, the two No. 3 lights of the main tester and remote tester will not turn on.
»
If several cables are not connected, several lights will not turn on respectively. If less than two cables are connected, none of the lights is on.
»
If two ends of the cable is disordered, for example No. 2 and No. 4, then displays on:Main Tester : 1-2-3-4-5-6-7-8-GRemote Tester : 1-2-3-4-5-6-7-8-G
»
If two cables are short circuited neither of the corresponding lights is on of the remote tester while main tester remains unchanged. If three cables, including three, are short circuited, none of the corresponding lights is on.
If test patch panels or wall plate outlets, two cables which can match each other (eg 110P4 and RJ45) will be connected to the tester. If test cables of the same axes, BNC turns on when the cable works.
