2007 POWER FINDER™ Circuit Tracer
HOW THE POWERFINDER™ OPERATES
The PowerFinder is composed of two primary components:
the receiver and the transmitter. When the transmitter is
plugged into any 9-300 Volt AC or DC source (680 VAC or
1000 VDC when using the 38583 High Voltage Adapter), it
draws a very small current (8-100 mA) in a very unique
manner: the current drawn is a crystal-controlled, precision
combination of four separate frequencies. This composite
signal gives it a specialized Signature.
To be received, the signal must have this exact combination
of frequencies.
This feature greatly reduces the possibility of interference
from electrical noise, which is often caused by lamps,
appliances, fluorescent fixtures, or machinery that is sup-
plied by the same power source as the circuit being traced.
The current drawn by the transmitter generates a magnetic
field signature around the conductor being traced which
matches the current itself. This magnetic signature is
present the entire length of the current path, including
through breakers, fuses, switchgear, and transformers.
The PowerFinder™ receiver is tuned to pick up only that
magnetic signature produced by the transmitter.
