2.1 AT-6010-R Receiver
The AT-6010-R Receiver detects the signal in wires and cables. The signal is generated by the AT-
6010-T Transmitter, which is connected to the wire.
The main advantage of this method is the ability to trace the path of the particular wire using
the Receiver. Since the signal is not present in any neighboring wires, the Receiver will
detect only the wire that is connected to the Transmitter.
Note: The Receiver will NOT detect signals from a wire through metal conduit or shielded cable. Refer
to Special Applications, section 4.4 “Tracing Wires In Metal Conduit” for alternative tracing methods.

2.2 AT-6010-T Transmitter
The AT-6010-T Transmitter works on Energized and De-energized circuits up to 600 V AC/DC in
Category I through Category III electrical environments.
Transmitter signal modes:
High Signal (Hi) – The HIGH mode function is recommended for most wire tracing applications
on Energized and De-energized circuits including breaker location. This function will be used
majority of the time.
Loop mode – This mode is initiated by short pressing On/Off button. Loop LED is On when this
mode is activated. It should be used when working with closed loop De-energized circuits, such
as shorted wires, shielded cables or De-energized wires that are grounded on the far-end.
How is the Loop function different from the Hi setting when using test leads?
HIGH mode (Hi) generates a signal in all open branches of the De-energized circuit. This is useful
when tracing open wires. Hi mode will NOT work on wires that are grounded on the far-end
because the signal cannot be generated.
Figure 2.2a: Generating a signal with HIGH mode
Loop mode generates a signal (current flow) in closed loop De-energized circuits only. Loop
mode is used to pinpoint the location of a short (because the current will not be able to flow in
open branches) and to trace wires that are grounded on the far end (because the loop is closed
via ground connection).
2. KIT COMPONENTS
7
Figure 2.2b: Generating a signal in Loop mode
Note: Loop mode only works on De-energized circuits. It is automatically disabled when the
Transmitter is connected to an Energized line with test leads.
Working with the Transmitter:
When the Transmitter is on and connected to the circuit with test leads, it checks for voltage.
A red Voltage Warning Indicator will light up if the Transmitter detects dangerous voltage levels
above 30 V AC/DC.
IMPORTANT!
The Voltage Warning Indicator light will blink when overvoltage (> 650 V AC/DC) is detected. In
case of overvoltage immediately disconnect the Transmitter from the circuit.
This Voltage Waning Indicator is not designed to check for absence of voltage. Please use a
voltage tester instead.
The Transmitter starts generating a tracing signal as soon as it is turned on. Based on the detected
voltage, the Transmitter automatically switches to either:
Energized mode (30 to 600 V AC/DC) generating 6 kHz frequency
De-energized mode (0 to 30 V AC/DC) generating 33 kHz frequency
Energized mode uses a lower transmission frequency (6 kHz) than De-energized mode (33 kHz)
to reduce signal coupling between wires. De-energized mode requires a higher frequency in
order to generate a reliable signal.
2. KIT COMPONENTS
8
Energized mode: In Energized mode, the Transmitter draws a very low current from the Energized
circuit and generates a 6 kHz signal. This is a very important feature of the Transmitter, since drawing
current does not inject any signal that would harm sensitive equipment connected to the circuit. The
signal is also generated in a direct path between the Transmitter and the power source, thus NOT
placing a signal onto any branches enabling wiring tracing directly back to the breaker panel. Please
note that due to this feature, the Transmitter has to be connected on the load side of the circuit.
De-energized mode: In De-energized mode, the Transmitter injects a 33 kHz signal onto the
circuit. In this mode, the signal will travel though all the circuit branches because it is injected.
The high frequency/low energy signal will not harm any sensitive equipment.

X� IMPORTANT NOTICE, PLEASE READ BEFORE STARTING TRACING
Avoiding signal cancellation problems with a separate ground connection
The signal generated by the Transmitter creates an electromagnetic field around the wire. This
field is what is detectable by the Receiver. The clearer this signal, the easier it is to trace the wire.
If Transmitter is connected to two adjacent wires on the same circuit (for example, hot and neutral
wires on a Romax cable), the signal travels in one direction through the first wire and then returns
(in opposite direction) through the second. This causes the creation of two electromagnetic fields
around each wire with opposite direction. These opposing fields will partially or completely cancel
each other out, making wire tracing difficult if not impossible.
To avoid the cancellation effect, a separate ground connection method should be used. The red
test lead of the Transmitter should be connected to the hot wire of the circuit you wish to trace,
and the green lead to a separate ground, such as water pipe, ground stake, metal grounded
structure of the building, or outlet ground connection of an outlet on a different circuit. It is
important to understand that an acceptable separate ground is NOT the grounding terminal
of any receptacle on the same circuit as the wire you wish to trace. If hot wire is Energized and
the Transmitter is properly connected to a separate ground, the red LED on the Transmitter
will light up. The separate ground connection creates maximum signal strength because the
electromagnetic field created around the hot wire is not being cancelled by a signal on the
return path flowing along an adjacent wire (hot or neutral) in the opposite direction, but
rather through the separate ground circuit.
3. MAIN APPLICATIONS
11
3.1 Tracing – Energized and De-energized Wires
Connecting test leads to the Transmitter
1. Connect the green and red test leads to the
Transmitter (polarity does not matter).
2. Using provided test leads accessories, connect the
red test lead to the wire being traced, Energized or
De-energized. For receptacles, make sure to connect
the test lead to the line (hot) wire. For Energized
systems the signal will ONLY be transmitted between
the load-side to which the Transmitter is connected
and the source of power (see Figure 3.1a).
3. Connect the green wire to a separate ground
(metal building structure, metal water pipe, or
ground wire on a separate circuit).
*Note: Please note that if working with GFCI protected
circuits, this method will trip the GFCI protection. Refer
to Special Applications, section 4.1 “GFCI-Protected
Circuit Wire Tracing” for alternative tracing methods.
TIP: The Transmitter, with the red test lead, can be directly connected to the live wire of the
working electrical equipment under load (motor, electronics, etc). Tracing can be performed
without needing to turn off the equipment or switching power off.
Figure 3.1b: Connecting Transmitter to Energized working system
Setting up the AT-6010-T Transmitter
1. Press ON/OFF key to turn on the Transmitter.
2. Verify that the test leads are properly connected;
the red LED voltage status light should be on for
circuits with voltage above 30 V AC/DC, and it should
be off for De-energized circuits below 30 V AC/DC.
Note: Make sure to use the separate ground
connection as described above.
3. HIGH signal mode is automatically activated when the
Transmitter is turned on. The LED on the Transmitter
should appear as in Figure 3.1c.

Using the AT-6010-R Receiver in Tracing Mode
Use Receiver to precisely pinpoint the wire location or the place of the fault. The Receiver will
indicate detected signal strength using a two digit readout, bar graph and sound.
1. Turn the Receiver on. Tracing mode is automatically activated.
2. Scan target area with the Tip Sensor to find the highest signal level. While tracing,
periodically adjust sensitivity to keep the signal strength near 50. Increase or decrease
sensitivity by pressing + or - on the keypad.
3. For best results while tracing Energized wires, align groove on the Tip Sensor with wire
direction as shown in Figure 3.1d. Signal may be not detected if not properly aligned. To
verify wire direction, periodically rotate the Receiver 90 degrees. Signal strength will be the
highest when wire is aligned with the Tip Sensor groove.
Depending on the detected signal, the Receiver automatically switches to either Energized
or
De-energized mode, and displays this information on the LCD. No manual setup is necessary.

Note: For best results, keep the Receiver at least 3 feet from the Transmitter and test leads to
minimize signal interference.
3. MAIN APPLICATIONS - TRACING ENERGIZED AND DE-ENERGIZED WIRES

3.2 Identifying Breakers and Fuses (Energized and De-energized)
Note: For breaker locating, a simplified direct connection to hot and neutral wires can be used
because these wires are separated at the breaker panel. There is no risk of signal cancellation
effect if wires are at least a few inches away from each other. However, the separate ground
connection (section 3.1) should be used for superior results specifically if wires need to be
traced in addition to breaker identification.
The simplified direct connection to hot and neutral wire will NOT trip the GFCI circuit.
Figure 3.2b: Separate ground connection
(Preferred)
Figure 3.2a: Simplified direct connection
Connecting the test leads
1. Connect the Transmitter using either simplified direct connection or separate ground connection.
2. If the simplified direct connection method is used, connect the test leads directly to the hot and
neutral wires. While locating a breaker, wires will not be traceable as the signals will cancel each
other out.
3. For separate ground connection, connect the red lead to the line (hot) wire on the load side of the
system. The wire can be energized or de-energized. Connect the green lead to a separate ground,
such as a metal building structure, metal water pipe, or ground wire on a separate circuit.
TIP: The Transmitter, with the red test lead, can be directly connected to the live wire of the
working electrical equipment under load (motor, electronics, etc). Tracing can be performed
without needing to turn off the equipment or switching power off.

Figure 3.2c: Connecting Transmitter to Energized working system
Setting up the AT-6010-T Transmitter
1. Press the ON/OFF key to turn on the Transmitter.
2. Verify that the test leads are properly connected. The red LED voltage status light will
illuminate for Energized circuits with a voltage above 30 V AC/DC. If the voltage is
De-energized, the light will be off.
3. HIGH signal mode is automatically activated when Transmitter is turned on.
Using the AT-6010-R Receiver
1. Turn the Receiver on. Tracing mode is automatically activated.
2. Align the groove on the Tip Sensor with the breaker lengthwise (See Figure 3.2d).
3. Scan all breakers in any order to find a breaker with the highest signal. Adjust sensitivity by
pressing + or - on the keypad to show the signal strength near 50 for the breaker with the
highest signal. After any sensitivity adjustment rescan all breakers to find the one with the
highest signal level.
Important note: Differentiation in breaker designs, height and internal contact structure may
affect the precision of breaker identification. For most reliable results, remove the breaker panel
cover and perform a scan on the wires instead of the breakers.
Depending on the detected signal, the Receiver automatically switches to either Energized
or
De-energized mode, and displays this information on the LCD
.

4.1 GFCI-Protected Circuit Wire Tracing: Connecting the AT-6010-T Transmitter to GFCI
Protected Circuits
Connecting the Transmitter to an Energized GFCI protected circuit using a separate ground
method will trip the GFCI protection. Use the following methods to work with GFCI protected
circuits. For a De-energized GFCI-protected outlet that is not tripped, you can connect test leads
directly to the outlet contacts using the De-energized Tip Sensor mode.
Method 1 – Bypass the GFCI circuitry to avoid tripping GFCI:
(for Energized GFCI-protected outlets only)
Remove the protective receptacle wall plate.
Using the alligator clip, attach the red test lead to the screw to connect the Energized hot
wire to the receptacle.
Connect the green test lead using a separate ground method.
Perform tracing as described in sections 3.1 or 3.2.
Method 2 – Do NOT use separate ground to avoid tripping GFCI:
(for GFCI-protected outlets and breakers)
Connect the Transmitter with the test leads to the Neutral and Hot wires.
Perform tracing as described in sections 3.1 or 3.2.
Note: This type of connection causes signal coupling and reduces signal strength. If the signal is
too weak or untraceable, use Method 3.
Method 3 - De-energize the circuit:
(for GFCI-protected breakers)
Connect the Transmitter directly to the wire as described in section 3.1.
Perform tracing as described in sections 3.1 or 3.2.
4.2 Finding Breaks/Opens
It is possible to pinpoint the exact location where a wire is broken, even if the wire is located
behind walls, floors or ceilings.
1. Make sure that wire is De-energized.
2. Use the steps described in section 3.1 to connect the Transmitter and perform tracing.
3. For best results, ground all De-energized wires that run in parallel with the black test lead.
Figure 4.2: Locating a break or open
4. SPECIAL APPLICATIONS
16
4. SPECIAL APPLICATIONS
The tracing signal generated by the Transmitter is conducted along the wire as long as there is
continuity in the metal conductor. To find a fault, trace the wire until the signal stops. To verify the
fault’s location, move the Transmitter to the other end of the wire and repeat, tracing from the
opposite end. If signal stops at the exact same location, the fault has been located.
Note: If the place of the fault is not found, the result may be a high resistance break (partially
open circuit). Such a break would stop higher currents from flowing but will conduct the tracing
signal through the break. Such faults will not be detected until the wire is completely open.
4.3 Finding Shorts
Shorted wires will cause a breaker to trip. To correct this, disconnect the wires and make sure the
ends of the wires on both sides of the cable are isolated from each other and other wires or loads.
1. Connect the Transmitter with the test leads to the circuit as shown in Figure 4.3.
2. Switch the Transmitter to Loop mode by short press of On/Off button. Verify that the Loop LED is ON.
3. Turn on the Receiver. Tracing mode is automatically activated.
Start tracing the cable until the signal stops. To verify the place of the fault, move the Transmitter
to the other end of the wire and repeat tracing from the opposite end. If the signal stops at the
exact same location the fault has been located.
Figure 4.3: Tracing a cable to find shorts
Note: This method will be affected by signal cancellation effect. Expect a relatively weak signal.
4.4 Tracing Wires in Metal Conduit
The Receiver is unable to pick up the signal from a wire through a metal conduit. The metal
conduit will completely shield the tracing signal.
Note: The Receiver will be able to detect wires in a non-metallic conduit. For these applications
follow general tracing guidelines.
To trace wires in a metal conduit:
1. Turn on the Receiver. Tracing mode is automatically activated.
2. Open junction boxes and use the Receiver Tip Sensor to detect which wire in the junction

Note: Applying a signal directly to the conduit will send the signal through all the conduit
branches, making tracing a particular conduit path impossible.
