Direct Connect; Hard Coupler Connection - SubSurface Instruments PL-TT Series User Manual

Direct Connection is the most reliable method of signal application. This method is relatively free of
interference. The greatest amount of signal strength can be achieved by this method. Low, mid, and
high frequency may be used. The far end of the utility must be grounded.
Connect the r
point or an exposed metallic section of the utility.
Place the G
from this point, at an angle of 90º to the buried
cable or pipe. Push the G

The Hard Coupler is very easy to use, and services do not have to be interrupted. The operation range
is shorter than for Direct Connection methods. The tracing signal can be affected by neighboring cables
and pipes. The Red/Black Test Cord or the Ground Rod Prove (GPR) are not needed for this method.
Successful coupler operation requires an insulated conductor that is grounded on both near and far
ends.

It is important to connect the coupler around
the cable needing to be traced. Connect the
coupler around the wire closer to the outgoing
cable not near the system ground. The result
will be a stronger signal. By connecting near
the grounding, the range will also be shorter,
and difficulty may arise determining one cable
from another.

Some couplers are frequency specific, others can operate on medium and high frequencies.
