2.1 AT-7000-RE Receiver

The AT-7000-RE Receiver detects the signal generated by the AT-7000-TE transmitter along wires

using either the TIP SENSOR or SMART SENSOR and displays this information on the full color TFT

LCD display.

Active tracing using a signal generated by the AT-7000-TE Transmitter

The SMART SENSOR works with a 6 kHz signal generated along energized wires (above 30V

AC/DC) and provides an indication of the wire position and direction relative to the receiver.

The SMART SENSOR is not designed to work on de-energized systems; for that application

the TIP SENSOR should be used in de-energized mode.

The TIP SENSOR may be used on either energized or de-energized wires and can be used for

general tracing, tracing in tight spaces, locating breakers, pinpointing wires in bundles or in

junction boxes. The TIP SENSOR mode will pinpoint the wire location with both an audible

and visual indication of detected signal strength, but unlike SMART SENSOR mode it will not

provide wire direction or orientation.

Note: The receiver will NOT detect signals from the 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-7000-TE Transmitter

The AT-7000-TE Transmitter works on energized and de-energized circuits up to 300V AC/DC

in Category I-IV electrical environments.

The transmitter will measure the line voltage and display it on the transmitter’s color

TFT LCD display screen. Based on detected voltage it will automatically switch to either

energized mode (30 to 300V AC/DC) or de-energized mode (0 to 30V AC/DC). The energized

mode uses a lower transmission frequency (6kHz) than de-energized mode (33 kHz) to

reduce signal coupling with nearby metallic objects and improve results. If the circuit is

energized the red LED in the upper left corner of the AT-7000-TE transmitter will light.

IMPORTANT! Note that the red LED light will turn on when connected to an energized

circuit. Select the correct energized or de-energized mode on the AT-7000-RE receiver when

choosing your tracing mode.

Energized mode: In energized mode the transmitter draws very low current from the

energized circuit and generates a 6.25 kHz signal. This is very important feature of the

AT-7000-TE, 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 32.8 kHz signal onto the

circuit. In this mode, since the signal is injected, it will travel through all the circuit branches.

It is a high frequency, very low energy signal that will not harm any sensitive equipment

when there is no access to the bare

conductors. The clamp attachment enables

the AT-7000-TE Transmitter to induce a

signal through the insulation into either

energized or de-energized wires. The

signal will travel through the wire in both

directions and into all the branches. This

transmission method will not damage any

sensitive electronic equipment connected to

the circuit.

• �IMPORTANT NOTICE, PLEASE READ BEFORE YOU START 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, Line

and Neutral wires), the signal travels in one directions through the first wire and then

returns (with opposite direction) through the second one. This causes 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 Neutral connection method should be used.

The red test lead of the transmitter should be connected to the Line wire of the circuit

you wish to trace and the green test lead to a Neutral wire either directly at the RDC

or at the closest connection point to the RCD as it is possible. Please make sure that Line

wire and separate Neutral are connected to the same RCD, otherwise the RCD will trip.

Proper connection will be indicated by the red LED on a transmitter to light up. If the LED

is OFF, make sure the circuit is energized and the red test lead is connected to Line wire,

and green to the Neutral. The separate Neutral connection creates the maximum signal

strength, because the electromagnetic field created around the Live wire is not being

canceled by a signal on the return path flowing along an adjacent wire (Line and Neutral)

in the opposite direction, but rather through the separate Neutral circuit. Please note

that connecting a test lead to Ground instead of Neutral, will trip the RCD. The ground

connection can be used for circuits that are not protected by the RCD.

3. MAIN APPLICATIONS

12

3.1 Tracing Energized Wires

SMART SENSOR

The SMART SENSOR enables easier wire tracing by

showing the direction and position of the wire and

is the recommended method for tracing energized

wires (does not work on de-energized circuits, use

de-energized TIP SENSOR for that application).

Connecting transmitter test leads

1. Connect green and red test leads to the

transmitter (polarity does not matter)

2. Connect red lead to energized Line 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 (see Figure 3.1a).

(refer to section 2.2 for further explanation).

3. Connect green lead to a separate Neutral wire

at the RCD or at a connection point as close to

the RCD as it is possible.*

*Note: Please make sure that Line wire and

separate Neutral are connected to the same RCD, otherwise the RCD will trip.

Set up the AT-7000-TE 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

indicator should be on, indicating that the

circuit is energized.

3. Select HIGH signal mode for most

applications. Screen will appear as shown

in Figure 3.1b.

Note: The LOW signal 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 a large area. The LOW signal

mode function is rarely used, only for most

demanding precise wire tracing applications.

ATTENTION: The transmitter voltage indication by LED or measurement on the LCD is not

sufficient to assure safety. Always verify the voltage presence/absence with approved

voltage tester.

Using AT-7000-RE Receiver

1. Press ‘ON/OFF’ push button to turn on the receiver and wait for the home screen (boot

up time is around 30 seconds).

2. Select SMART SENSOR mode by using the directional arrows to highlight this operating

mode and pressing the yellow ENTER button.

3. Hold the receiver with the Smart Sensor on the rear of the unit facing the target area.

If the screen flashes a “?” in a red target then no signal is detected. Move the Smart

Sensor closer to the target area until the signal is detected and you see a directional

arrow. If no signal is detected increase the sensitivity using the “+” button on the

receiver. (see Figure 3.1c)*

4. Move the Receiver in direction indicated by the arrow on the screen (see Figure 3.1d)

5. Green target symbol indicates that the Receiver is directly over the wire (see Figure

3.1e). If Receiver will not lock on the wire, decrease sensitivity using the “-“ on the

keypad or set the transmitter to transmit at LOW signal mode.

6. Press ENTER when complete to return to Home screen.

*Note: For best results, keep the receiver at least 1 m (3 feet) from the transmitter and

its test leads to minimize signal interference and improve wire tracing results. Select the

“Long” Smart Sensor Range in the Settings Menu if working with wires that are located

behind walls, floors or ceilings deeper than 1m (3 feet).

3.2 Tracing Energized Wires

TIP SENSOR

TIP SENSOR mode is used for the following

applications: pinpointing a wire in a bundle,

tracing in corners and confined spaces such as

junction boxes or inside enclosures.

Connecting transmitter test leads

1. Connect green and red test leads to the

transmitter (polarity does not matter)

2. Connect red lead to energized Line 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 (see

Figure 3.2a).

3. Connect green lead to a separate Neutral wire

at the RCD or at a connection point as close to

the RCD as it is possible.

*Note: Please make sure that Line wire and separate Neutral are connected to the same

RCD, otherwise the RCD will trip.

Set up the AT-7000-TE 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

indicator should be on, indicating that the

circuit is energized.

3. Select HIGH signal mode for most

applications. Screen will appear as shown in

Figure 3.2b.

Note: The LOW signal 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 a large

area. The LOW signal mode function is rarely

used, only for most demanding precise wire

tracing applications.

The transmitter voltage indication by LED or measurement on the LCD is not sufficient to

assure safety. Always verify the voltage presence/absence with approved voltage tester.

Using AT-7000-RE Receiver

1. Press ‘ON/OFF’ push button to turn on the receiver and wait for the home screen (boot

up time is around 30 seconds).

2. Select Energized TIP SENSOR mode by using the directional arrows to highlight this

operating mode and pressing the yellow “ENTER” button. Screen as shown in 3.2e will

appear.

3. Hold the receiver with the Tip Sensor facing the target area.

4. Scan target area with Tip Sensor to find highest signal level. While tracing, periodically

adjust sensitivity to keep signal strength near 75. Increase or decrease sensitivity

by pressing + or – on the keypad. If signal is too strong for precise locating, change

transmitter to LOW mode.

5. Receiver Positioning: For best results, align groove on tip sensor with wire direction as

shown. Signal may be lost if not properly aligned. (see Figure 3.2c)

6. To verify wire direction, periodically rotate receiver 90 degrees. Signal strength will be

highest when wire is aligned with Tip Sensor groove. (see Figure 3.2d)

7. Press ENTER when complete to return to Home screen.

Note: For best results, keep the receiver at least 1 m (3 feet) from the transmitter and its

test leads to minimize signal interference and improve wire tracing results.

3.3 Tracing De-energized Wires

TIP SENSOR

De-energized TIP SENSOR mode is used for general

wire tracing, pinpointing wires in bundles, tracing

in tight corners and confined spaces such as

junction boxes or inside enclosures.

Connecting transmitter test leads

1. Connect green and red test leads to the

transmitter (polarity does not matter)

2. Connect red lead to de-energized Line wire

(on the load side of the system).

In de-energized mode the signal will be

injected to ALL branches of the circuit, not

just between the outlet and the breaker as in

energized modes.

3. Connect green lead to a separate ground

(metal building structure, metal water pipe,

or ground wire / Protective Ground (PE) on a

separate circuit).

ATTENTION: Due to safety reasons this is only

allowed in de-energized circuits. (see figure

3.3a) Do not use a ground wire that runs in

parallel to the wire you are going to trace, as

it will reduce or cancel tracing signal.

NOTE:If circuit is energized you will trip RCD.

Set up the AT-7000-TE Transmitter:

1. Press ON/OFF key to turn on the transmitter.

2. The red LED voltage status indicator should be off, indicating that the circuit is de-

energized. If LED is on, disconnect power to the circuit.

3. Select HIGH signal mode for most applications. Screen will appear as shown in Figure 3.3b

Note: The LOW signal 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 a large area. The LOW signal mode function is rarely used, only for

most demanding precise wire tracing applications.
