Two Person - Pipehorn Series 800-H User Manual

For Full Coverage
Re-locate the 800-H Transmitter at least once several steps to
the right or left in order to provide complete coverage. This is
because any conductor which is directly underneath the Trans-
mitter will not be detected.
Pinpoint and Determine Signal Source
As with normal Inductive Locating, place the 800-H Transmitter
upright on one of the marks made earlier, (in line with the sus-
pected run of the conductor). Pinpoint the conductor on the
other side of the search area in the normal manner, as described
on page 11.
After pinpointing the conductor, raise the receiver toward the
Transmitter to be sure the signal is mostly coming from the con-
ductor and not through the air, as described on page 13.
Repeat this process for each of the HIGH pitch areas found ear-
lier and mark the lines accordingly.
SEARCH AND SWEEP

Two Person

Generally, two people can perform a search over a broad area
quicker than one person.
Set Up the Search
Start over an area where there are no conductors. One person
holds the Transmitter to his/her side in line with the suspected
run of the conductor(s). The other person stands approximately
30 feet away from the Transmitter, holding the Receiver to his/
her side. (Be sure the receiver is set to receive High-frequency,
page 8.) Turn both units ON, and keep them pointed at each
other. Set the Receiver's sensitivity control so that the meter
reads 4 and you hear a LOW pitched tone. The tone will get
higher as you get closer to conductors.
