Test conditions
To avoid test errors:
• Do not test near strong magnetic fields (magnets, loudspeakers,
transformers, motors, coils, relays, contactors, electromagnets,
etc.).
• Do not test near strong electrostatic fields (high voltage power
lines, televisions, computer monitors, etc.).
• Do not test near strong RF fields (radio or television transmitters,
walkie-talkies, cellular phones etc.).
5.2 Test ing an RJ45 cable
Never use the tester on live wires; this may cause shocks
or damage the meter.
Notes
•
Only one cable can be tested at a time. For example, a coaxial
cable and an RJ45 cable cannot be tested simultaneously.
• The tester is intended to test complete cables. It may no find
faults in cables that are intentionally incomplete. For example, the
standard EIA/TIA 568 RJ45 terminated Ethernet cable is expected
to contain 8 conductors. If only 4 conductors are used between
the RJ45 connectors, the device may not properly identify the
faults.
To test a cable:
1. Insert one end of the cable under test into the appropriate
socket in the master.
2. Insert the other end of the cable into the corresponding socket
in the remote.
3. Press and release the Test button [1].
The power LED will light up for at least 5 seconds, indicating the
device is testing the cable. If the power LED does not light,
replace the battery.
5.3 Test result
The tables below describe the test results (LEDs that light up and
number of beeps) for various error types.
