1. Safety information
◆The cable tester is intended to use in compliance with the local rules of the electrical usage and avoid to apply
at the places which are inapplicable for the use of electrics such as hospital, gas station etc.
◆To prevent the functional decline or failure, the product should not be sprinkled or damped.
◆The exposed part of the cable tester should not be touched by the dust and liquid.
◆During transportation and use, it is highly recommended to avoid the violent collision and vibration of the
tester, lest damaging components and causing failure.
◆Don't leave the tester alone while charging and recharging. If the battery is found severely hot, the tester should
be powered off from the electric source at once. The tester should not be charged over 10 hours.
◆Don't use the tester where the humidity is high. Once the tester is damp, power off immediately and move
away other connected cables.
◆The cable tester should not be used in the environment with the flammable gas.
◆Do not disassemble the instrument since no component inside can be repaired by the user. If the disassembly is
necessary indeed, please contact with the technician of our company.
◆The instrument should not be used under the environment with strong electromagnetic interference
◆Don't touch the tester with wet hands or waterish things.
◆Don't use the detergent to clean and the dry cloth is suggested to use. If the dirt is not easy to remove, the soft
cloth with water or neutral detergent can be used. But the cloth should be tweaked sufficiently.

3. Operation
3.1 Installing the Battery
The tester has built-in lithium ion polymer rechargeable battery. The battery cable inside battery cabin should be
disconnected for safety during transportation!
Prior to the use of the instrument, the battery cables inside the battery cabin should be well connected.
When the battery icon is full or the charge indicator turns off automatically, indicate the battery charging is
completed.
Notice: Please use the original adaptor and connected cable of the device!
3.2 Auto power off function
The meter can set 10-120 minutes auto power off, or close the auto power off function. Can set power off time in
Setting function.
If you don’t press key, the meter will start the auto power off. If you press the key, the meter will retime. TheAuto
power off is off by default.
3.3 OSD Menu
Press key to choose the function, the Icon of screen means has menu interfaces. Select the

4. Cable tester
4.1 UTPcable test
Connect the network cable into the cable tester’s RJ45 port, the BNC cable or RJ11 telephone line connect to the
cable tester’s BNC or RJ11 port. If no connector cable, can use alligator clips to clip the bare copper wire.
Press key to select the “SCAN UTP”function, press the key to enter cable tracer interface.
4.1.1 Cable tracer
The UTPmode and STPmode can be optional. The UTP mode is for searching the normal cable or other cable.
The STPmode is for searching shielded cable.
Turn on the wire receiver, can search cable. Rotating the knob of receiver to adjust the sensitivity. When the cables
are very close, can adjust to the small sensitivity to find the cable.
Long press the “MUTE” key for silent mode. In this mode, the signal strength indicator light is used to trace the wi
re. When received the strongest signal, the eight indicator lights are on. Press “MUTE” again to exit MUTE
mode.
(1) Quickly verify the tracking result (only for RJ45 port).
After found the cable, connect the network cable to wire receiver “UTP” port for pair line detection. For example,
When the "Straight/Cross/Other" lights up, indicates the verification of the matching cable. The indicator also
shows the type of the cable. The 1-8 and G indicators show the detection of line sequence by default, and the order
in which the indicator lights up is the sequence of the line.
(2) Port continuity detection:
Connect the network cable into the cable tester’s RJ45 port, the other end of network cable to cable tester’s RJ45
port. Press “MUTE” button, when the indicator light of port is on, the 1-8 and G indicator lights will show the
