4. SPECIAL APPLICATIONS

4.10 Mapping a Circuit using Test Leads Connection

Mapping a circuit can be only performed on a De-energized circuit when using test leads
connection.
1. Switch the breaker to the OFF position.
2. Set up the Transmitter and Receiver as described in the Precision Tracing section 3.1.
3. Scan face plates of receptacles and wires connecting loads with the Tip Sensor of the
Receiver
4. All the wires, receptacles and loads that have a strong signal as indicated by the Receiver
are connected to the breaker.

4.11 Tracing Breakers on Systems with Light Dimmers

Light dimmers can produce a significant amount of electrical "noise" that consists of
multi-frequency signals. In some rare situations, the Receiver can misread this noise, often
called a "ghost" signal, as a Transmitter - generated signal. Therefore, the Receiver may
provide wrong readings.
When locating breakers or fuses on systems with light dimmers, the dimmer should be off
(the light switch is off). This prevents the Receiver from indicating a wrong breaker/fuse.

4.12 Signal Clamp - Closed Loop Circuits

Closed loop, De-energized and low impedance circuits
The clamp accessory is used for applications where there is no access to a bare conductor
to connect the test leads. When the clamp is connected to the Transmitter, it enables the
Transmitter to induce a signal to the Energized or De-energized wire through the insulation.
Typical applications of the Signal Clamp include tracing conduits or shields grounded on
both ends. For signal cables and De-energized wires or loads, temporarily ground the circuit
on both ends to perform tracing.
