cable. The connectors can also be damaged by excessive
insertion and removal or flexing of the cable close to
connector body.
While the WireMaster XR-5 can identify a bad cable, it
cannot 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.
7.3
Which end is bad? The XR-5, like many cable testers,
cannot 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.
7.4
Cables with Molded on ends: Many cables have molded
on ends that cannot 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.
7.5
Cables with Crimped on RJ connectors: Crimped on
RJ connectors cannot be reused or repaired. New
connectors must be installed on the cable. If the cable
being tested has just been "made up" or put in service,
and it tests as Open or Crossed, the RJ connectors have
probably been installed incorrectly. Shorts very seldom
occur as the result of a badly crimped RJ connector, so
the user should suspect a problem with the wire (possibly
a staple or nail through the wire, or a crushed or pinched
wire) if the XR-5 indicates a Short. A visual examination
of the RJ connectors may reveal the fault...... but keep in
mind that whatever the cause of a connector problem
(i.e., miswiring, improper stripping of the wire, bad
crimp, etc.), the only solution is to replace the connector.
Consequently, it is not necessary for the user to know
the exact cause of the problem, simply to make sure that
he installs the new connector correctly!
7.6
Conflicting Results: Sometimes, the tests results of the
XR-5 seem to conflict with the performance of the
cable........ i.e., the cable tests bad but works OK, or vice
versa. The following items list some of the reasons why.
7.6.1 The WireMaster XR-5 says my cable is bad, but my
LAN works OK: Installed LAN cables with RJ-45
connectors that have been in service and working OK
may test as Open, Shorted, or Crossed. Here's why.........
