If Something Seems Wrong With The Tester - Fluke Networks TS 100 Guia Del Usuario

TS100 Cable Fault Finder
Users Guide
A: If the cable has more than two conductors, and a
short exists at the far end between one of the
conductors you are connected to and a conductor you
are not connected to, the displayed length will be the
SUM of the lengths of the conductors joined by the
short. TS100 can only correctly test the two conductors
you are connected to. See "Applications" on page 7 for
multi-conductor cables.
Q: When testing a set of wires that go into a conduit, I
sometimes get a reading of 0 or 1. Why?
A: If there is more than a foot or so of wires that are
physically separated before they enter the close
confinement of the conduit, this will look to the tester
like an open at the start of the cable. Remember that
TS100 reports the FIRST failure that it finds. Try
bringing the two wires of the pair closer together for
the path from TS100 to the entry to the conduit.
Q: When connecting to a 6 foot (2 meter) piece of 50
Coax with the alligator clips, the tester reads 8 feet (3
meters). What's up?
A: When measuring a low impedance small cable (less
than 15 feet [5 meters]), the clip leads can add up to 2
feet (1 meter) of length. For longer or high impedance
cables, the clip leads have no effect.
Q: How does the tester react to a speaker or a
transformer at the end of a cable?
A: A speaker or a transformer is actually a large coil of
wire. This will usually cause the length reading to be
larger than that of the cable alone. A moderate power
speaker will add 500 feet (150 meters) to the length
reading. Some combinations of speakers and
transformers connected to the cable may prevent the
tester from making a valid reading.

If Something Seems Wrong
with the Tester
The display remains at 8.8.8.8. after power on.
The self test has failed. The batteries may be weak or
the tester has water inside. Try changing the batteries
or drying the tester.
The tester reads less than 10 feet (3 meters)
regardless of the length of the cable.
The connection to the cable is broken. Check your
connection to the cable for dirt or insulation. Also, test
the clip leads by shorting them and listening for the
beeper. You can also visually check the center
connection of the BNC for damage.
The tester does not respond to any button presses.
The batteries could be dead or inserted incorrectly, or
the contacts are dirty or broken. Please ensure that
nothing is connected to the input connector before
opening the battery door, and then check the battery
installation. Remove the batteries and check the
contacts for dirt or damage. Please observe correct
polarity when inserting the batteries.
