For positive identification of the pair, momentarily short the
pair to active the TrueTrace feature. If this is the target pair,
the cadence of the tracer tone will change.
In the grounded method (also called Line to Ground), one
clip of the FOX 2 (either the red or green) is connected to
earth ground or a “fake ground”, and the other clip is con-
nected to the target wire. The target wire can be one wire of
a pair or a multiwire cable. (see Figure 4) This method cre-
ates the strongest tracer tone, and is often used when wires
are traced through walls or ceiling. It is also useful for iden-
tifying a specific wire within a bundle of wires. If connection
to a true ground is not available, a large metal object can be
used as a fake ground. For example, a large metal desk or a
metal file cabinet can be used. When tracing wires in a car,
trailer, or RV, etc. the metal frame or body can be used as a
ground. When tracing wires in a boat (that is in the water)
with a wood or fiberglass glass hull, any piece of metal that
comes in contact with the water can be used as a ground.
Simply connect one clip of the FOX 2 to the ground or fake
ground, and the other clip to the target wire.
TrueTrace can be used in conjunction with the grounded
method of tracing if the ground that is used at the FOX 2
location is also available at the end location of the wires.
Simply short each suspect wire to the ground while listen-
ing for a cadence change with a HOUND or HOUND 2. If
water is used as the fake ground, it usually is not conductive
enough to activate TrueTrace.
