HARMONIC LOCATOR PROBE: LINE TRACING AND TAP DETECTION
The Harmonic Locator Probe provides two basic capabilities:
1.
An RF Line Tracer that operates at 225 kHz,
2.
A harmonic detector to locate the existence of an electronic tap.
This system consists of a Non-Linear Junction Detector in which the main TALAN unit provides
the transmit function, and the hand-held locator probe provides the receive function.
Basic procedure is the following:
1.
Connect the main TALAN unit to an isolated dry line without the phone or the switch
connected to the line.
2.
Then select Line tracing from the Manual menu and adjust the transmit power level
using the stylus.
3.
Using the Connections dashboard: select a wire pair that includes the conductor under
test and an unbalanced partner wire. The figure below shows a test of wire #4 with wire
#8 selected instead of the balanced partner (wire #5).
The best result is achieved when a single conductor is traced rather than a balanced pair
(this is because in a balanced pair, there is very little leakage, and the coupling between
the pair minimizes the ability to trace the wire.)
4.
Turn on the Harmonic Locator Probe (HLP).
5.
Test the locator probe by passing it over the wire to be traced.
