Sending Tone
With the test set in the TONE position, connect the modular
plug or the red/black leads to the subject wire(s). An internal
slide switch (accessible from the outside using a slender tool)
allows the selection of either a fast or slow warble tone output
(Figure 3).
With multiple signal connection methods, experiment to find the
methods that work best with your applications.
Optional connections include:
• Connect the modular plug to a six-position jack to apply signal
to the center two pins (USOC pair 1 only).
• Connect the red and black leads to the tip and ring conductors
of a twisted pair circuit.
• For high twist wires (e.g. LAN cat-5/6) connect the leads to
conductors of two different pairs. Example: red to tip of pair 1,
black to tip of pair 2.
• Connect the red lead to the subject wire and the black lead to
an independent earth ground.
• Connect the red lead to the shield and the black lead to
ground of a shielded or coaxial cable.
• Connect the red lead to the shield and black lead to center
conductor of a coaxial cable.
Trace the wire(s) with any Greenlee tone probe (Figure 4). When
pair tracing, in order to confirm that the correct pair has been
