3. MAIN APPLICATIONS – LOCATING BREAKERS/FUSES
Using AT-6000-RE Receiver
1. Press 'ON/OFF' push button to turn on the receiver and continue pressing MODE button
until Breaker/Fuse mode is selected.
2. Align the groove on the Tip Sensor with the breaker/fuse lengthwise (See figure 3.2b).
3. Scan all breakers/fuses. The order of scanning does not matter. You can scan breakers/
fuses multiple times. The receiver is recording the highest signal level and automatically
adjusts sensitivity. The receiver may beep and the green arrow may light up several
times during this step.
4. Locate the breaker/fuse - scan all breakers/fuses again; the receiver should indicate
only one breaker/fuse.
Important note: Differentiation in breaker/fuse designs, height, internal contact structure
may affect precision of breaker/fuse identification. For most reliable results, remove the
breaker/fuse panel cover and perform scan on the wires instead of breakers/fuses.
Scan the breakers/fuses always at the same position and alignment of the tip sensor.
A variation may affect improper results.
If more than one breaker/fuse is indicated during the last step,
continue scanning the indicated breakers/fuses until only one is
positively identified.
Depending on the detected signal, the receiver automatically
switches to either Energized
displays this information on the LCD. No manual setup is necessary.
The automatic sensitivity adjustment can be reset or adjusted using
-/+ 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/fuse identified by the
receiver is the highest among all breakers/fuses.
Before you start the next locating process for new circuit or a branch,
connect the transmitter and reset the receiver by either pressing +
button to select higher sensitivity or switching receiver off and then on.
