UNDERSTANDING NVP
The CableTool makes a very precise measurement of the time it takes for an
electrical signal to travel down a cable, hit a short or open and travel back to the
unit. The time is converted into length based on the speed that the electrical signal
travels along the cable being tested. Different cables have different electrical
properties and the speed that the electrical signal travels will vary based on the
NVP of the cable.
NVP (Nominal Velocity of Propagation) is the relative speed that an electrical
signal will travel through a media. A vacuum is a perfect media with an NVP of
100. All cables have an NVP less than 100 and typically in the range of 50 to 80.
Using the most accurate NVP available will provide the most accurate length
measurements.
The NVP for electrical service cables (such as Romex, BX, UF-B) varies
significantly between manufacturers and even between production lots from the
same manufacturer. Data cables have special manufacturing processes that
produce fairly consistent NVP values. The NVP of a cable can also be different if it
is wound on a spool or laying flat (installed). Data cables have the least variation
between wound and flat and some coaxial cables show significant variation. NVP
is specified for many types of cable and may be printed on the cable spool or
box. Contacting the manufacturer or checking their website can also be a good
source of accurate NVP information. Using the Custom Cable Setup to determine
the NVP of a known cable length provides accurate results. The NVP values
prestored in the CableTool provide typical values for cable types from all
manufacturers.

BATTERY
The CableTool operates on four AA alkaline
batteries. Remove the battery cover at the back of
the unit and insert the batteries with the orientation as
shown. Battery polarity is marked inside the battery
well for reference.
INTRODUCTION
The CableTool Multifunction Cable Meter electrically measures the length of a
cable using Time Domain Reflectometry technology. The CableTool measurement
begins by transmitting an electrical pulse into the connected cable. The electrical
pulse travels along the cable until it hits a discontinuity (either a short or an open)
and is then reflected back to the unit. The CableTool precisely measures the time
between launching the pulse and recieving the reflected pulse. The time
measurement is converted to distance using the cable NVP (Nominal Velocity of
Propagation).
Additionally, the CableTool provides a continuous reading of any voltages
present on the cable under test and features four different tone frequencies and
patterns for tracing cables with a tone probe.
MECHANICAL FEATURES
SAFETY
Always disconnect the test leads from any cable before opening the battery
compartment cover.

OVERVIEW
The CableTracker Model 15 Probe identifies cables and terminations by detecting a
trace tone signal transmitted by the CableTool. When the Probe is near the correct cable
pair or punchdown, it indicates detection by emitting an audible signal with the same
pattern that is selected on the CableTool.
CABLE TRACING
Connect the CableTool to a cable. Turn on the Model 15 Probe by pressing and
holding the button. Place the probe tip near the cable or termination to be identified and the
Probe will emit an audible signal. The audible signal is loudest when the Probe is near the
correct cable or termination point. The volume can be adjusted by rotating the thumbwheel
located above the button. The Power ”ON” indicator is illuminated when the unit is on and
the battery has adequate voltage.
BATTERY
The CableTracker Model 15 Probe operates on one 9 volt alkaline battery. Remove
the battery cover at the back of the unit, connect the battery to the battery snap cable, insert
the battery in the battery well and replace the battery cover.
BATTERY LIFE
The Model 15 Probe will operate for approximately 16 hours on one 9 volt alkaline
battery. When the battery is below the level required for the Model 15 to operate properly,
the Power “ON” indicator will not illuminate.
OPERATION
Attach the test leads to the CableTool by inserting the safety banana plugs
into the banana jacks at the top of the unit. Turn the CableTool on by pressing the
“PWR” button. The startup screen is shown for a few seconds and then the Mode
Screen is displayed. Clip one test lead to each of two conductors of the cable to
be tested.
MODE SCREEN
When the Mode Screen is displayed, the CableTool immediately starts
measuring voltage and updates the reading
several times per second. If more than a 6-8
volts are present on the cable, do not conduct a
Length test or apply a Tone signal until the
circuit is de-energized. The CableTool can
withstand continuous input voltages of up to 250Vrms.
LENGTH SCREEN
Pressing the Length function key in the Mode Screen presents the Length
Screen. The CableTool automatically starts
measuring the distance to the fault (open or
short) using the NVP of the Default Cable (see
Default Cable Setup). Using the Up/Down
Cursor key, any of the eight user selected cable
types, the four custom cable types or a cable type from the prestored cable list
can be selected and the length is corrected for the corresponding NVP. The length
measurement is continuously updated.
When the NVP for a cable is known to be different than the displayed NVP,
the NVP can be changed by pressing the Select
function key to move the arrow to the NVP field
and then pressing the Up/Down cursor key to
modify the NVP. The NVP can also be modified
and stored in Cable List setup.
RECOMMENDATION: Before starting a job with a new spool or box of cable
that has a known length, make a length measurement with the CableTool to
determine if the prestored NVP for that cable type provides the correct length. This
is done by selecting a cable type that matches or is similar to the type of cable to
be tested, press the Select function key to move the arrow to the NVP field and
press the Up/Down Cursor key until the displayed length matches the known
length printed on the box or spool. The modified NVP will only be used while
making this length measurement, exiting the screen or turning off the power will
reset the NVP to the original value. To store the cable type with the modified NVP
see “Cable List Setup”. The prestored NVP is a typical value and adjusting the
NVP to the actual length will provide more accurate results. See “Understanding
NVP” for more information.
