6.1.2 Methods of Applying Signal to a Utility
- The three methods of applying the signal to the
utility are - Direct Connect, Inductive Coupling, and Inductive. Following is a description of each
method and instruction of use.
A
Direct (Conductive) Connection
- This is the preferred mode of operation because the
transmitter is connected directly to a metallic part of the utility (hydrant, meter, riser, valves,
sheath, and tracer wire), allowing maximum signal to reach the utility. In this operating mode the
Receiver can be closer to the Transmitter, and adjacent buried utility interference is reduced.
1
Insert the Conductive Attachment -
Turn the
Transmitter off. Insert the Direct Connect
Cable into the OUTPUT JACK on the Transmitter.
2
Set up and connect to a ground
- Extend the
BLACK lead of the Direct Connect Cable
at a right angle as far as possible from the utility. Press the ground spike into the ground
as far as possible, then attach the black clip. If the ground spike cannot be used,
connect to appropriate ground using an extension reel. Look for a convenient existing
ground, such as a metal street sign. Be careful not to get close to or cross any adjacent
buried utility. If no existing ground is available, use the ground spike. Drive the ground
spike as far into the ground as possible, and attach the BLACK lead. See Figure 6-1.
3 Connect to your utility
- Connect the RED
lead of the Direct Connect Cable to the
targeted utility. Make sure of good metal to metal contact.
