In Case Of Unstable Or Unusual Readings; Applications - Fluke Networks TS100 Mode D'emploi

To determine the VOP of a known length of cable:
Connect a known length of cable to the tester. The
1
cable must be 200 feet (60 meters) or longer (such
as an unopened box of wire).
Turn the tester on while holding down the UP or
2
DOWN button. In this mode, the display
alternately shows the VOP setting (-VV-) and the
calculated length (LLLL).
When the length setting is displayed, press the UP
3
or DOWN button. This keeps the length value on
the display for adjustment.
Use the UP and DOWN buttons to adjust the
4
length to the length of the cable.
To exit the VOP adjustment mode, turn the tester
5
off.
While the tester is in VOP adjustment mode,
tone is not injected into the cable.
The VOP value reverts to the default of 66 when
you change the tester's batteries.

In Case of Unstable or Unusual Readings

Sometimes, devices connected to the cable you are
testing can prevent the TS100 from making a valid
reading. Such devices include telephones, fax
machines, modems, speakers, transformers, light bulbs,
televisions, and DC loads. The software makes the best
decisions it can when faced with unusual conditions,
but may not always be able to ignore connected
devices. If you get a highly unstable or clearly invalid
reading, check for devices connected to the cable.
Notes

Applications

See Figure 3.
The tester locates opens, short circuits, and crosses in
any two metallic conductors (twisted, untwisted, coax,
copper, aluminum, and steel).
It identifies conductors using the PowerTone feature
and an inductive probe (not included) (see Figure 2).
Tone can be sent between two technicians to ID
multiple pairs. Because the tester beeps when it detects
a short circuit, it also serves as a circuit (for example,
continuity) tester.
