SeekTech ST-305 Line Transmitter
Using the ST-305 Line
Transmitter
The SeekTech ST-305 line transmitter is part of
Ridgid's Seektech cable and pipe locating system.
The ST-305 is used to energize a pipe or line with an
"active" electrical signal, so that the underground line
may be traced with a compatible receiver (such as
the Seektech SR-20). This allows the line's location
to be correctly marked so it can be exposed for repair
or avoided during excavation.
The ST-305 line transmitter can apply an active
tracing signal to a target conductor in three ways:
Direct Connect – The transmitter's leads are
connected directly to the target conductor and a
suitable ground. See page 8.
The ST-305 is capable
transmission (sending two frequencies onto a line
simultaneously) in direct-connect mode. See page
10.
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 11.
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 11.
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.
Remove the ground stake from the end of the unit
and insert it into the ground. Connect one of the
cable leads to the grounding spike. The leads are
universal, so either may be used for the ground.
