2.1 AT-6000-R Receiver
The AT-6000-R Receiver detects the signal in wires and cables using the following methods:
Active (using Transmitter)
The AT-6000-T Transmitter generates a signal capable of tracing either Energized or De-energized wires.
The main advantage 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.
The active tracing method is used when the Receiver is set to Quick Scan, Precision Tracing
or Breaker Locating.
Passive (without Transmitter)
The passive method utilizes the Receiver by tracing Energized wires between 90-600 V AC
through electromagnetic fields.
This method is both easy and convenient because it does not require the Transmitter.
However, the Receiver is not selective to a particular wire and will indicate any Energized
wire between 90-600 V AC.
This method is best for simple tracing applications where the wire is Energized and no other
wires are located nearby.
Passive tracing method is used when the Receiver is set to Non-contact voltage (NCV) detection mode.
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.

TACTILE BARRIER

The AT-6000-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 the majority of the time.
Low Signal (Lo) – The LOW mode function is only appropriate for the most demanding and
precise wire tracing applications, as it limits the signal level generated by the Transmitter
in order to pinpoint the wire location more precisely. A lower signal level reduces coupling
to neighboring wires and metal objects, which avoids misreadings due to ghost signals. A
lower signal also prevents oversaturating the Receiver with a strong signal that covers too
large of an area.
Loop mode – This mode is initiated by pressing and holding this Hi button for two seconds.
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 or Lo settings when using test leads?
Both HIGH and LOW modes generate a signal in all open branches of the De-energized
circuit. This is useful when tracing open wires. Hi/Lo modes will NOT work on wires that are
grounded on the far-end because the signal cannot be generated.
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 grand connection).
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.
If the High (Hi) or Low (Lo) Signal button is pressed momentarily, the Transmitter starts
generating a tracing signal. 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.
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.

3.1 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. Plug the socket adapter onto the receptacle and
connect the red lead to the Energized hot wire
(on the load side of the system). 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.
Setting up the AT-6000-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. Select HIGH signal mode by pressing HI for
most applications. Screen will appear as
shown in Figure 3.1b. The LED display will
quickly begin to blink.
Note: The LOW signal precision mode can be
used to limit the signal level generated by the
Transmitter in order to more precisely pinpoint
wire location. A lower signal level reduces coupling
to neighboring wires and metal objects and helps
to avoid misreading due to ghost signals. A lower
signal also helps to prevent oversaturating the
Receiver with a strong signal that covers too large
an area. The LOW mode function is only used
for the most demanding and precise wire tracing
applications.

Using the AT-6000-R Receiver in Quick Scan Mode
Quick Scan mode detects wires at a longer distance (between a wire and the Receiver) but
with less precision than Precision Tracing or Breaker modes. This feature is used to verify that
the tracing signal is present and to quickly follow the path of the wire. Switch to Precision
Tracing mode to precisely pinpoint the wire, or to Breaker mode to locate a breaker.
1. Press ON/OFF push button to turn on the Receiver. It will automatically start in Quick
Scan mode, which is the default.
2. Scan a target area with the Tip Sensor to find a signal, then begin tracing the detected
wire. Increase or decrease sensitivity of the Receiver by pressing + or - on the keypad as
necessary.
3. For best results while tracing Energized wires, align groove on the Tip Sensor with wire
direction as shown in Figure 3.1c and 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 away from the Transmitter and test
leads to minimize signal interference.

Using the AT-6000-R Receiver in Precision Tracing Mode
Use Precision Tracing mode 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. Press the MODE button until the Precision Tracing function is selected.
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. If the signal is too strong for precise
locating, change the Transmitter to LOW mode.
3. For best results while tracing Energized wires, align groove on the Tip Sensor with wire
direction as shown in Figure 3.1e. 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

3.2 Identifying Breakers and Fuses (Energized and De-energized)
Breaker mode automatically adjusts the sensitivity of the Receiver. As a result, the Receiver
will pinpoint and indicate just one correct breaker. This enhancement helps to remove signal
strength analysis from the breaker identification process that is typical for less advanced
wire tracers.
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 (see pg. 11) 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.
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, first connect the red lead to the Energized hot wire
on the load side of the system. The signal will ONLY be transmitted between the outlet
to which the Transmitter is connected and the source of power.
4. Connect the green lead to a separate ground, such as a metal building structure, metal
water pipe, or ground wire on a separate circuit.
Setting up the AT-6000-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. Select the HIGH signal mode for Breaker Locating.

Using the AT-6000-R Receiver
1. Press the ON/OFF push button to turn on the Receiver and continue pressing the MODE
button until Breaker Locating mode is selected.
2. Align the groove on the Tip Sensor with the breaker lengthwise (See Figure 3.2c).
3. Scan all breakers in any order. Breakers can be scanned multiple times. The Receiver
records the highest signal level and will automatically adjust sensitivity. The Receiver
may beep and the green arrow may light up several times during this step.
4. Locate the breaker by scanning all breakers again; the Receiver should indicate only
one breaker.
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.
If more than one breaker is indicated during the last step, continue scanning the indicated
breakers until only one is positively identified.
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. The automatic sensitivity adjustment can be reset or adjusted using the +/- buttons.
Usage Tip: The accuracy of breaker
identification results can be verified by
switching the Receiver to Precision Tracing
mode and checking that the signal level of
the breaker identified by the Receiver is
the highest among all the breakers.
Before starting the next locating process
for new circuit or a branch, connect the
Transmitter and reset the Receiver by
either pressing + button to select high
sensitivity or switching the Receiver off
and then on.
