Inductive Mode - RIDGID 20168 Operator's Manual

Clamp the inductive clamp around an accessible
portion of the line chosen to trace. The clamp will
induce a signal into the conductor when the
transmitter is powered on.
Select frequency and power as with the Direct
Connect Method. Operational frequency choices for
use with an Inductive Clamp are 1 kHz, 8 kHz, and
33 kHz.

1. Be sure that the transmitter is positioned
correctly over the line.

Note: A slight tilt to the axis of the conductor can
help reduce the probability of air-coupling:

2. Power the transmitter on. Push the Inductive
Mode switch to induce a signal onto the line
without a direct connection. (A long beep will
sound when entering Inductive Mode.) The
Inductive Mode LED will light .
3. Clips and leads are not used. Note that for a
clear signal using induction, both ends of the
utility should be grounded.
4. The transmitter will emit a series of regular
beeps as long as it is in Inductive Mode.

5. Lower frequencies couple poorly; therefore the
NaviTrack Brick transmitter in Inductive Mode
defaults to 33KHz. Higher power is usually
required for a clear signal in Inductive Mode.
Pressing the power button will cycle through
the three available power levels: 1 kHz, 8
kHz, and 33 kHz.
To avoid tangled cords, wrap the cords back around
the ends of the NaviTrack Brick when storing, lead
end last, and secure the ends under the prongs
provided on the transmitter.
NOTE: If using the Brick in Inductive Mode, be
certain to switch Inductive Mode off if you are
going to use the unit in direct connect mode. Air
coupling can create very confusing signals if you
inadvertently have the unit set to Inductive Mode
and are trying to use it in direct connect mode.
