3. MAIN APPLICATIONS – LOCATING BREAKERS
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
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.
