2. KIT COMPONENTS
2.1 AT-6010-R Receiver
The AT-6010-R Receiver detects the signal in wires and cables. The signal is generated by the AT­6010-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. KIT COMPONENTS
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).
6
2. KIT COMPONENTS
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.
7
2. KIT COMPONENTS
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.

3. MAIN APPLICATIONS
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 - TRACING ENERGIZED AND DE-ENERGIZED WIRES
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 3.1a: Proper connection with
separate ground
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.

3. MAIN APPLICATIONS - TRACING ENERGIZED AND DE-ENERGIZED WIRES
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 De-energized mode, and displays this information on the LCD. No manual setup is necessary.

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 3.2a: 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 De-energized mode, and displays this information on the LCD

4. SPECIAL APPLICATIONS
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
15
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 box is carrying the signal.
3. Move from junction box to junction box to follow the path of the wire.
Note: Applying a signal directly to the conduit will send the signal through all the conduit branches, making tracing a particular conduit path impossible.
16
4. SPECIAL APPLICATIONS
4.5 Tracing Non-Metallic Pipes and Conduits
The Transmitter can indirectly trace plastic conduits and pipes using the following steps:
1. Insert fish tape or wire inside the conduit.
2. Connect the Transmitter with the red test lead to the fish tape and the green ground wire to a separate ground (see section 3.1 for further set-up instructions).
3. Turn on the Receiver and trace the conduit. Tracing mode is automatically activated.
4. The Receiver will pick up the signal conducted by the fish tape or wire through the conduit.
4.6 Tracing Shielded Wires
Shielded wire prevents the Receiver from detecting a tracing signal when following the standard user instructions. To effectively trace shielded wire, follow these procedures.
If shielded wire is grounded at the far-end:
1. Switch the Transmitter to Loop mode by short press of On/Off button. Verify that the Loop LED is ON.
2. Disconnect the ground on the near-end of the shielded wire and connect the shield to one of the terminals of the Transmitter (polarity does not matter) with a test lead.
3. Connect the second output of the Transmitter to a separate ground.
4. Turn on the Receiver and trace the shield. Tracing mode is automatically activated.
Figure 4.6a: Tracing a shielded wire grounded at the far-end
If shielded wire is disconnected from ground at the far-end:
1. Connect the Transmitter directly to the wire as described in section 3.1.
2. Disconnect the ground on the near-end of the shielded wire and connect the shield to one of the terminals of the Transmitter (polarity does not matter) with a test lead.
3. Connect the second output of the Transmitter to a separate ground.
4. Turn on the Receiver and trace the shield. Tracing mode is automatically activated.

4.7 Tracing Underground Wires
The AT-6010 can trace Energized and De-energized wires underground the same way it can locate wires behind walls or floors. Follow general wire tracing instructions in section 3.
Figure 4.7: Tracing underground wires
4.8 Tracing Low Voltage Wires and Data Cables
The AT-6010 can trace data, audio and thermostat cables (to trace shielded data cables, refer to section 4.6).
Trace data, audio, and thermostat cables
1. Connect the Transmitter using the separate ground method described in section 3.1.
2. Turn on the Receiver and trace the wire. Tracing mode is automatically activated.

4.9 Sorting Bundled Wires
Identify a specific wire in a bundle
1. Connect the Transmitter as described in section 3.1. If connecting to an Energized wire, make sure the Transmitter is connected on the load side.
2. Turn on the Receiver. Tracing mode is automatically activated.
3. One at a time, pull each wire away from the others and touch it with the Tip Sensor. The strongest signal indicates the proper wire in the bundle.
4. Adjust the Receiver sensitivity as required with +/- buttons.

4.10 Mapping a Circuit using Test Leads Connection
Mapping a circuit can be only performed on a De-energized circuit when using test leads connection.
1. Switch the breaker to the OFF position.
2. Set up the Transmitter and Receiver as described in the section 3.1.
3. Scan face plates of receptacles and wires connecting loads with the Tip Sensor of the Receiver
4. All the wires, receptacles and loads that have a strong signal as indicated by the Receiver are connected to the breaker.

4. SPECIAL APPLICATIONS
4.11 Tracing Breakers on Systems with Light Dimmers
Light dimmers can produce a significant amount of electrical “noise” that consists of multi-frequency signals. In some rare situations, the Receiver can misread this noise, often called a “ghost” signal, as a Transmitter - generated signal. Therefore, the Receiver may provide wrong readings.
When locating breakers or fuses on systems with light dimmers, the dimmer should be off (the light switch is off). This prevents the Receiver from indicating a wrong breaker/fuse.
4.12 Signal Clamp (optional accessory) - Closed Loop Circuits
Closed loop, De-energized and low impedance circuits
The clamp accessory is used for applications where there is no access to a bare conductor to connect the test leads. When the clamp is connected to the Transmitter, it enables the Transmitter to induce a signal to the Energized or De-energized wire through the insulation. Typical applications of the Signal Clamp include tracing conduits or shields grounded on both ends. For signal cables and De-energized wires or loads, temporarily ground the circuit on both ends to perform tracing.
Connecting the Signal Clamp
1. Connect the CT-400 test leads to the terminals of the Transmitter (polarity does not matter).
2. Clamp the CT-400 Signal Clamp around the conductor. To increase the signal strength, wind a few turns of the conductor wire around the clamp if possible.
Figure 4.12a: Connecting the clamp
Setting up the AT-6010-T Transmitter
1. Press the ON/OFF key to turn on the Transmitter. The red LED voltage status indicator should be OFF when the clamp is connected and when working with either Energized or De-energized systems.
2. Short press ON/OFF button to select the Loop mode on the Transmitter (LOOP red LED will be ON). The clamp mode generates a boosted 6 kHz signal in order to provide superior tracing results. The LED on the Transmitter should appear as in Figure 4.12b.

4. SPECIAL APPLICATIONS
Using the AT-6010-R Receiver
1. Turn on the Receiver. Tracing mode is automatically activated.
2. Hold the Receiver with the Tip Sensor facing the target area.
3. Scan the target area with the Tip Sensor to find the highest signal level. While tracing, periodically adjust the sensitivity to keep the signal strength near 50. Increase or decrease the sensitivity by pressing + / - on the keypad.
4. Receiver Positioning: For best results while tracing Energized wires, align the groove on the Tip Sensor with the wire direction as shown. The signal may be lost if not properly aligned.
5. To verify the wire direction, periodically rotate the Receiver 90 degrees. Signal strength will be highest when wire is aligned with the Tip Sensor groove.
4.13 Signal Clamp (optional accessory) - Mapping Circuits
The clamp accessory can be used to map loads to the specific breakers on both Energized and De-energized circuits. There is no need to disconnect the power.
1. Connect the CT-400 test leads to the terminals of the Transmitter (polarity does not matter) and select HIGH mode.
2. Clamp the CT-400 around the hot (line) wire at the breaker panel.
3. Set Receiver sensitivity to the maximum level by pressing + button.
Scan the face plates of receptacles and wires by touching them with the Tip Sensor of the Receiver. All the wires, receptacles and loads that the Receiver indicates by reading a signal are connected to the breaker.
Note: Expect a relatively weak signal. For best performance, install new batteries to the Transmitter. Use the “Mapping a circuit using test leads connection” method if a much stronger signal is required.
