Conductive Locating - Pipehorn Series 800-H User Manual

Conductive Locating

Conductive locating is done when there is an access point avail-
able for direct connection to the target conductor. This technique
applies maximum signal to the target conductor with minimal
signal applied to adjacent conductors.
The 800-H puts out the High-frequency during Conductive Locat-
ing. Conductors, such as deep high-pressure gas mains, com-
munication cables, and other insulated continuous pipes and
cables, tracer wire and tape which may have breaks, as well as
poor conductors like cast iron with partially insulating couplings
are all candidates for HF locating.
Only licensed or authorized persons should make direct connec-
tions. DO NOT HOOK DIRECT TO LIVE POWER CABLES.
Make certain that the owner of the conductor has authorized di-
rect hook-up for purposes of locating.
Appling Signal to the Conductor
Remove any rust, paint, or other insulating substances from the
point of contact with the conductor.
Position the supplied Ground Rod as far away from and 90° from
the conductor as possible. Try to avoid grounding over an adja-
cent conductor. Connect to the Conductor, then to Ground, then
insert the phono plug into the jack, and last, turn the Transmitter
ON.
