About this Manual
Introduction
The FaultChaser is a self-contained, hand-held, battery powered test unit operated by
contractors, repair technicians, and other authorized users. This device is used to
accurately test voice, data, and video cables. The FaultChaser determines cable length,
identifies cable faults, and quickly discovers the Nominal Velocity of Propagation (NVP)
for a cable using Spread Spectrum Time Domain Reflectometry (SSTDR).
Symbols and Icons
The following symbols are used throughout the manual or in the display screen of the
FaultChaser to help you avoid personal injury and potential damage to the test
equipment (Table 1).
Table 1. Symbols and Icons
Symbol
Definition
Warning: Potential for personal injury.
Caution: Potential for damage or destruction to equipment.
Voltage! Voltage detection symbol. Appears when the voltage on the cable is unsafe
and exceeds 60 Volts peak AC or DC.
Conformité Européenne. Conforms with European Economic Area
directives.

Terms and Descriptions
Table 2 defines the terms used throughout the document and provides information to
assist you with proper operation and understanding of the unit and its functions.
Table 2. Terms and Descriptions
Terms
Description and Uses
Nominal Velocity of
Propagation (NVP)
Also known as the Velocity of Propagation (VOP), NVP is
the speed of an electrical signal traveling through a cable,
measured as a percentage of the speed of light.
Safety Extra Low
Voltage (SELV)
•A rating determined by the International Electrotechnical
Commission that defines safe voltage standards when
using electronic devices.
•SELV is 60 Volts for DC systems or 42.5 volts RMS for
AC systems.
F-Connector Connector for a coax cable.
Spread Spectrum Time
Domain Reflectometry
(SSTDR)
•Spread spectrum is the technological foundation of cell
phone communications and is used to transmit a small,
but nevertheless recognizable, signal in a high noise
environment.
•By combining spread spectrum with TDR technology,
SSTDR allows for a length test on cables without
interference from voltage.
5
Safety Information
To ensure safe operation of the FaultChaser, follow the instructions carefully and
observe the warning and caution messages listed in Table 3. Failure to observe
warnings can result in severe injury or death and can damage the unit.
Table 3. Safety Information
Notification Definition
The FaultChaser is designed for use on cabling systems with or without
voltage.
•The Voltage! Icon turns on when the voltage exceeds Safety Extra
Low Voltage (SELV) rating of 60 Volts peak AC or DC.
•Internal components are protected up to 400 Volts peak AC or DC.
•Operating the FaultChaser when a voltage source exceeds 60 volts
peak AC or DC may pose a safety hazard for the user.
Do not place equipment and its accessories in the trash. Items must be
properly disposed of in accordance with local regulations.
It is not recommended to use the FaultChaser when the Voltage! Icon is
present.

FaultChaser Description
The FaultChaser, illustrated in Figure 1, has 3 main parts: the F-Connector, LCD display
screen, and the keypad.
Figure 1. FaultChaser
F-Connector
One F-Connector is located at the top of the FaultChaser. The connector enables you
to test and measure single cables.
Note: Additional accessories are provided with your purchase of the FaultChaser for
use with twisted pair, coaxial, and two wire cables. Refer to the Cable Testing
General Guidelines section of the manual for more details.

LCD Display Screen
The FaultChaser has a high contrast LCD display screen, shown in Figure 2 below. The
LCD display screen shows the following: modes and related icons, cable length,
memory storage and related icons, NVP value, cable faults, error message, voltage
detection warning, and battery life indicator.
Figure 2.LCD Display Screen
Test Mode
When the TEST button is pressed, the measured cable length (in units of feet or meters)
appears at the top of the LCD display screen. The following values and icons display in
the screen when a single test is run:
•Storage Location – The selected storage location (M1 or M2) appears in the lower
left corner of the display screen above the NVP value.
•NVP Value – The value saved in the selected storage location appears in the lower
left corner of the screen. This value is used to calculate the displayed cable length.
