For RJ45,RJ12,RJ11&BNC1.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-GRemote tester:1-4-3-2-5-6-7-8-GFollowing 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-GRemote tester:1-4-3-2-5-6-7-8-G4.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.
