5 in 1 Cable Tester RTK-T05 User Manual
6
Connected LED/3 Beepers/Short LED/Numbered LEDs: If the Connected LED lights, the Beeper emits 3 beeps,
and the Short LED lights, the cable has a fault. The numbered LEDs indicate the location of a short.
Note:
In the Short mode, the Numbered LEDs only indicate the location of the shorts. The other connections in the cable are
not indicated. If more than 3 numbered LEDs light, there may be multiple shorts in the cable.
Connected LED/2 Beepers/Cross LED/Numbered LEDs: If the Connected LED lights, the Beeper emits 2 beeps,
and the Cross LED lights, the cable has a fault.
Note:
In the Cross-mode, the Numbered LEDs indicate connections but do not indicate the location of the cross. RJ-11 cables
used for telephone connections are often crossed. Even new cables are often crossed. This seldom affects the
performance of standard analog telephone lines (POTS). Digital telephone lines and old touch-tone phones may be
polarity sensitive, so a crossed cable may prevent them from working properly.
7. CABLE REPAIR
General Information
The following section provides information to the user about common cable types, common failures, and repairs. It is
not meant to be an exhaustive study of the topic, just some basic information that the uninitiated may find helpful.
Cable Damage
When a cable tests badly, either the wire or the connectors or both may be at fault. If the cable has been installed and
working, then it’s likely that the wire or connectors have been abused in some way. The wire portion of the cable can be
damaged by being crushed (under the left of a desk), stretched (pulled sharply around a corner), punctured (by a nail or
staple), over loaded (hit by lighting), etc. Similar abuses will damage the connectors on the ends of the cable. The
connectors can also be damaged by excessive insertion and the removal or flexing of the cable close to connector body.
While the 5 in 1 can identify a bad cable, it can not determine if the wire or the connectors are at fault. The user must
examine the different parts of the cable to determine the cause of failure and take the appropriate steps to correct the
problem.
Which end is bad?
The 5 in 1 like many cable testers, can not find the location of the fault, or even determine which end or connector is bad.
It simply knows that a fault exists. The user must locate the fault and take the appropriate action.
Cables with Molded on ends
Many cables have molded on ends that can not be opened up for repair. The entire cable must be replaced, or the
molded on end removed and replaced with a user serviceable connector. These types of cables usually fail from Opens
or Shorts. They seldom fail from a Crossed connection.
