must be aware at all times of where the grounding cables run and what is used
as a ground. The cables are carrying the full signal current, and, if the operator
should ground over the top of or close to another conductor, the other conductor
may be energize and jeopardize the locate (Figure 2-6). If a foreign structure
such as a chain link fence is being used for ground, that structure will also be
energized and could confuse the operator. Always be aware of the importance
and function of the ground in the DIRECT CONNECT application.
Once the conductor is energized using the direct connect method, the operator
may use the receiver to search for the signal using the same techniques described
in the one operator sweep. Since there is now a direct connection to the conduc-
tor, the inductive antenna on the transmitter is not active. The operator can now
work closer to the transmitter and not be affected by air coupling. It should be
understood that the operator will start picking up signals near the grounding
cables as they are radiating the same signal carried by the target conductor.
Dual Jacking – (the Conductive Mode with two direct connections –
grounding kits)
As with the single Conductive (direct connect) method as illustrated in Figure
2-6, the operator may perform two direct connections as follows:
With the Sure-Lock, the operator may use two direct connections using two fre-
quencies – 8.1 and 81 kHz. The operator will need two direct connect (ground-
ing) cables to perform this function.
With a single hook-up as illustrated in Figure 2-6, the Sure-Lock direct con-
nection attachment is plugged into one of two output jacks, the 8.1 and 81 kHz
ranges. The red lead is attached to the pipe/cable and the black lead is attached
to the grounding spike.
The same procedure is followed when attaching two separate direct connection
Therefore, the operator will have one set of direct connection attachments
plugged into the 81 kHz output jack and the second set plugged into the 8.1 kHz
output jack.
**NOTE**
REMEMBER THAT THE SIGNAL ON THE GROUND WIRE IS AS
STRONG AS THE SIGNAL ON THE CONDUCTOR.
