Locating Loads (Signal Clamp); Tracing Breakers On Systems With Light Dimmers - Beha-Amprobe AT-7020-EUR Manual De Usuario

4. SPECIAL APPLICATIONS

4.11 Locating Loads (Signal Clamp)

The clamp accessory can be used to map loads to specific breakers on both energized and
de-energized systems. There is no need to disconnect power.
1. Clamp the SC-7000-EUR around the wire at the breaker panel.
2. Set up the transmitter and receiver as described in the previous section 4.10 "No Access
to Bare Conductors (Signal Clamp)".
3. Scan face plates of receptacles and wires connecting loads with the Tip Sensor of the
AT-7000-RE. If using on a de-energized system you must set the receiver to de-energized
TIP SENSOR mode.
4. All the wires, receptacles and loads that have a strong signal as indicated by the AT-
70000-RE are connected to the breaker.

4.12 Tracing breakers on systems with Light Dimmers

The light dimmers can produce significant amount of electrical "noise", that consists of
multi frequency signal. In some situations the receiver can miss-read this noise, often
called a "ghost" signal, as a transmitter generated signal. In such situation, the receiver will
provide wrong readings.
When locating breakers or fuses on systems with light dimmers, make sure the dimmer is off
(the light switch is off). This will prevent the receiver to indicate a wrong breaker/fuse.
