BREAKERS

Connecting transmitter test leads

1. Use test leads with standard plug

connection for receptacles and black and

red test leads with alligator clips when

connecting to wires.

2. Plug test leads into Transmitter. Polarity

is not important.

3. Connect plug to outlet, or if using test

leads connect them to hot and neutral

wires.*

* The separate ground connection as shown

in De-Energized TIP SENSOR should be used

for superior results specifically if wires

need to be traced in addition to breaker

identification.

Set up the AT-7000-T Transmitter:

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

2. The red LED voltage status should 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 breaker tracing.

Receiver Process Overview

Tracing breakers is a two-step process:

SCAN - Scan each breaker for one second. The receiver will record tracing signal levels.

LOCATE - The receiver will indicate the single breaker with the strongest recorded signal.

Using AT-7000-R 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 De-Energized BREAKERS mode by using the directional arrows to highlight this

operating mode and pressing the yellow “ENTER” button.

3. Step 1 -

SCAN

a) Select SCAN mode by using the directional arrows to highlight this operating mode

and pressing the yellow “ENTER” button.

b) Scan each breaker for a half second by touching it with the Tip Sensor. Make sure the

groove on the Tip Sensor is parallel to the breaker lengthwise

c) To assure sufficient time between the scans, wait for active green arrow and audible

alert (2-beeps) before moving to the next breaker.

d) Scan all breakers – the order of scanning does not matter. You can scan breakers

multiple times. The receiver is recording the highest detected signal.
