Instructions for productTurn on the tester. Meanwhile, the default of system is wire map testing, LCD display is as follows if the cable is not connected. Wire map testing (Take RJ45 as an example)Test Result1: Short circuit (SHORT)If there is short circuit of cable or terminal, three “tick, tick and tick” will come out from emitter. Meanwhile, LCD display the picture below: (take 3,4-short circuit as example)At this moment, press “TEST” key to restart again. If the short circuit still occurs, please solve “short” circuit problem before measuring.
Turn on the tester, connect one end of the cable to emitter, and the other end is connected to RJ45 port of remote identifier.Press “test” to start , if the cable is shielded (or earthing wire), LCD will display “STP”; if the cable is unshielde (or earthing wire), LCD will display “UTP”; press “light” key in dim environment.

Test Result 2: If the cable is not connect to the emitter or remote identifier, the launcher will produce “tick” one time and LCD displays the picture below in the meanwhile:Test Result 3: Normal wiring map (WIREMAP)If the cable is normal, the launcher will produce a long “tick” and LCD displays the picture below in the meanwhile. RJ45 cable without shielding wire RJ45 cable with shielding wireYour excellent helper in cable test!05

Test Result 4: When there is open circuit of cableThe emitter produces a long “tick” sound and LCD displays the picture below in the meanwhile: The result indicates that “3” “6” line of RJ45 cable is open.Test Result 5: When the cable is crossed /disorderThe emitter produces two short “tick, tick” and LCD displays the picture below in the meanwhile: The result indicates that “3” “6” line of RJ45 cable is cross. Test Result 6:When the cable is cross/disorder, as well as open circuit. The emitter produces two short “tick, tick” sound and LCD screen displays picture below in the meanwhile:The picture indicates that “3” “6” line of RJ 45 cable is cross and “2” “7” lines are in open circuit.Your excellent helper in cable test!06

Hunting test
Press “ON/OFF” , the equipment is started up with a long sound. Slightly touch “SCAN” key and enter hunting mode, LCD screen displays the following in flashing: Press “ON/OFF” , then the emitter will start working. Connect testing cable to corresponding port of the emitter (RJ45, RJ11, USB, BNC, 1394 and others),slightly touch “SCAN” key,and select the preferred tone (there are 9 kinds of frequency to be selected, press “SCAN” for your desired one,then take the receiver to hunt target wire (the usage of receiver is shown in the following) . Press “backlight” key when in dim environment.
Usage of the receiver
Dismount the battery cover, install battery of 9V, press “PUSH” key, then approach the cable with probe and find target wire required among lots of cables. When the probe is near target wire, the “beep, beep and beep” sound may occur and the signal indicator light “POWER” will be on.Compare volume of “beep,beep and beep” and luminance of signal indicator, the wire which makes sound is the loudest and the signal indicator is the brightest is target one.
