Using the ST-305 Line Transmitter
The ST-305 line transmitter can apply an active tracing signal
to a target conductor in three ways:
Figure 4
Figure 5
Figure 6
Direct Connect – The transmitter’s leads are connected
directly to the target conductor and a suitable ground.
The ST-305 is capable of dual-frequency transmission
(sending two frequencies onto a line simultaneously) in
direct-connect mode. See page 7.
Inductive Clamp – The jaws of the inductive clamp encircle
the target conductor; there is no metal-to-metal contact.
(The inductive clamp is an optional accessory). See page 7.
Inductive Mode (internal coils) – The transmitter is placed
over, and in-line with, a conductor. Its internal antenna
generates a dipole field which energizes the target conductor
below ground, inducing a current into the target conductor.
See page 8.
DANGER! Always connect leads before turning the
transmitter on to avoid electrical shock. Ensure transmitter
is well grounded.
Direct-Connect Method
1. Attach the ST-305 line transmitter to
ground and to the target line
Insert the ground stake into the ground. Connect one of the
cable leads.
Connect the other lead to the target conductor.
