OPERATING INSTRUCTIONS
Before testing, verify the Receiver is functioning properly by placing
it near the powered Transmitter. With the Receiver set to Sensitivity
Level 8, a numerical reading of 99, all 10 signal strength bars lit up,
and a strong audible signal confirms the system is working. The
Receiver will produce a variable beep proportional to the sensitivity
value. The higher the signal strength, the faster it will beep.
NOTE: A continuous beep or solid-on LED indicates strongest
possible signal of 99 and the Receiver is saturated.
NOTE: If the Transmitter is powered up normally but the Receiver
detects a very low signal level, even when set to the highest
sensitivity level, the internal protection fuse in the Transmitter
should be checked, as it may be blown.
CONNECTING TEST LEADS
Connect test leads by inserting the black lead into the "COM" jack and
the red lead into the "+ 600V" jack. Do not test if leads are improperly
seated. Results could cause intermittent display readings. To ensure
proper connection, firmly press leads into the input jack completely.
NOTE: Test leads used must have a CAT III 600V safety rating.

OPERATING INSTRUCTIONS
TRANSMITTER DIRECT AND REMOTE GROUND CONNECTION METHODS
DIRECT GROUND: In a direct ground connection, a plug or clips can
be connected to the hot and neutral wires on the same circuit.
NOTE: While locating a breaker, the wires will not be as traceable due
to the cancellation effects of the wires running parallel.
F
REMOTE GROUND: Preferred for optimum signal strength. To optimize
the transmitted signal and avoid cancellation effects which occur in a
direct ground connection, a remote ground connection should be used.
Attach the Ground ProngB to the 20' (6 m) Lead AdapterE and
connect to the ground of an outlet on a different circuit. Attach the red
Blade ProngA to the red test leadD and connect to the hot wire of
the circuit you are tracing.
E D
A
B
NOTE: This Remote Ground connection method will trip GFCI receptacles.
Several workarounds are available: Use the Direct Ground method,
connect directly to wires with alligator clips

OPERATING INSTRUCTIONS
RECEIVER ORIENTATION
The orientation of the Receiver in relation to the wire being traced is very
important. The vertical Crosshair Groove
7
on the tip of the Receiver
indicates the preferred direction of the wire for the strongest signal
detection. While tracing a wire, rotate the Receiver to always ensure the
highest signal value is displayed. The signal may not be detected if the
Receiver tip is not properly aligned to the wire. If the signal drops, the wire
may have changed direction (horizontal to vertical or vertical to horizontal).
Whenever possible, keep the Receiver at least 3' (0.9 m) away from the
Transmitter and test leads to reduce signal interference.

APPLICATIONS
WIRE
Circuit Breaker Finder (energized and de-energized)
1. Connect the Transmitter to the circuit to be identified using either the direct
ground or remote ground connection and power the Transmitter on. The
direct ground and remote ground connection methods can be used on both
energized and de-energized circuits, but an energized circuit produces a higher
signal strength.
2. Verify that the Energized Indicator on the Transmitter is illuminated if
connected to a circuit with voltage above 25V AC/DC and is not illuminated for
de-energized circuits.
3. Go to the electrical panel and power on the Receiver. If there is more than one
panel, touch the tip of the Receiver to each panel cover to identify the panel
4
with the highest signal level. Use the Increase Sensitivity
and Decrease
Sensitivity 5 buttons to adjust the Receiver sensitivity level to identify the
panel with the highest reading.
4. Once the panel has been identified, open the cover.
5. Orient the Receiver facing left or right and perpendicular to the breakers (See
below). Slowly move the Receiver up and down in front of each breaker. Use
4
the Increase Sensitivity
buttons to adjust the Receiver sensitivity levels as
5
and Decrease Sensitivity
needed to locate the breaker with the highest reading.
After any sensitivity level changes, rescan all the
breakers to find the breaker with
the highest reading.
NOTE: Energized circuits typically use
sensitivity levels 1-3, and de-energized circuits may need
higher sensitivity levels 4-8.
NOTE: If two or more breakers have the same signal value,
remove the panel cover and place the tip of the Receiver on
the individual wires to help in determining the correct breaker.
NOTE: Ensure the wire is held in the proper orientation in
relation to the tip of the Receiver.

OPERATING INSTRUCTIONS
TRACING WIRES
1. Connect the Transmitter to the circuit to be traced and power on
the Transmitter.
NOTE: The direct ground and remote ground connection methods
can be used on both energized and de-energized circuits, but an
energized circuit produces a higher signal strength.
2. Power on the Receiver, and use the Increase Sensitivity button 4
to set the Sensitivity Level to 8 (highest level).
3. Starting a few feet from the Transmitter, slowly move the Receiver
around to locate the direction of the strongest signal. The wires may
be located behind the wall, in the ceiling, or underneath the floor.
NOTE: If the signal strength displays “99”, the signal is saturated.
Use the Decrease Sensitivity button 5 to reduce the sensitivity level.
NOTE: If the signal strength is too weak, use the Remote Ground
connection method (if not done already) to strengthen the signal.
4. Continue to follow the location of the highest signal strength until
the destination is reached.
NOTE: If the circuit is de-energized, the Transmitter can be
connected to the neutral and ground wires, which will create a
stronger closed loop signal, as neutral and ground are bonded
together at the panel.
TRACING LOW VOLTAGE AND DATA CABLES
Follow the same steps outlined for Tracing wire above, with the wires
de-energized and utlizing a remote ground connection method.
NOTE: For shielded cables, connect the red test lead to the shield
of the cable being traced. Ground the far end of the cable shield if
possible.
FINDING OPENS/BREAKS
Follow the same steps outlined for Tracing wire above, except make
sure to ground any other wires running in parallel with the wire being
traced. Follow the signal strength until you observe it starting to drop
off. Use the sensitivity arrow keys to lower the sensitity level to pin
point the location of the open/break.

ENGLISH
OPERATING INSTRUCTIONS
TRACING WIRES INSIDE METAL CONDUIT
Due to metal conduit shielding the wire being traced, the Receiver
will be prevented from picking up the signal from the Transmitter. To
trace wire inside of metal conduit:
1. Connect the Transmitter to the circuit to be traced and power on
the Transmitter.
2. Power on the Receiver, and use the Increase Sensitivity button
4
to set the Sensitivity Level to 8 (highest level).
3. Hold the Receiver in front of junction boxes to check for the signal
being transmitted from the Transmitter.
4. If there is no signal detected, the junction box may need to be opened
so that the tip of the Receiver can be held in front of each wire.
5. Continue along each junction box until the destination is reached
or until the end of the circuit.
NOTE: If the conduit is non-metallic, the standard wire tracing
steps can be followed.
MAPPING A CIRCUIT
1. Turn off the breaker of the circuit being traced.
2. Remove the hot wire from the circuit breaker and connect the red
test lead of the Transmitter to the wire.
3. Connect the black test lead of the Transmitter to a remote ground
(see the Direct and Remote Ground connection methods sections)
and then power on the Transmitter.
4. Starting a few feet from the Transmitter, use the tip of the Receiver
to scan face plates of receptacles, wires, and other loads.
NOTE: If the signal strength displays “99”, the signal is saturated.
Use the Decrease Sensitivity button 5 to reduce the sensitivity level.
NOTE: If the signal strength is too weak, use the Remote Ground
connection method (if not done already) to strengthen the signal.
Any locations which indicate a signal are connected to the specific
breaker.

OPERATING INSTRUCTIONS
TRACING UNDERGROUND
1. Connect the Transmitter to the circuit to be traced and power on
the Transmitter.
NOTE: The Receiver may not detect and trace easily through metal
conduit/pipe or shielded cables. If the conduit is metal, or the wire
is shielded, connect to the shield or conduit instead.
NOTE: For the strongest signal, the remote ground connection
method should be used.
NOTE: Leaving the circuit energized provides a stronger signal and
assists in tracing.
2. Power on the Receiver, and use the Increase Sensitivity button
to set the Sensitivity Level to 8 (highest level).
3. Starting a few feet from the Transmitter, hold the Receiver
perpendicular to the ground and slowly move it around using a
sweeping motion to locate the highest signal value. Pay close
attention to the orientation of the Receiver in relation to the wire
being traced. The signal may not be detected if the Receiver tip is
not properly aligned to the wire. If the signal drops, the wire may
have changed direction.
4
NOTE: If the signal strength displays “99”, the signal is saturated.
