3. MAIN APPLICATIONS - BREAKERS (Energized and De-Energized)
Energized and De-energized breaker/fuse locating
&
BREAKERS
Receiver Process Overview
Tracing breakers/fuses is a two-step process:
1
SCAN - Scan each breaker/fuse for one second. The Receiver will record tracing signal levels.
2
LOCATE - The Receiver will indicate the single breaker/fuse with the strongest recorded signal.
Using AT-8000-R Receiver
1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.
2. Select either Energized BREAKERS mode or De-Energized BREAKERS mode by using the
directional arrows and pressing the yellow ENTER button.

Step 1 - SCAN
1. The unit will automatically start in
2. Scan each breaker/fuse for a second by touching it with the Tip Sensor. Make sure the
groove on the Tip Sensor is parallel to the breaker/fuse lengthwise (Figure 3.3e).
3. To assure sufficient time between the scans, wait for active green arrow and audible
alert (2 beeps) before moving to the next breaker/fuse.
4. Scan all breakers/fuses – the order of scanning does not matter. You can scan each
breakers/fuses multiple times. The Receiver records the highest detected signal.
Usage tip: For best results try to scan at the output of the 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.
