the ground over the cable you wish to trace and turn it on. A
vertical position of the case increases the power induced into the
ground. Do not tightly shut the transmitter case as it will turn the
transmitter
off.
The
transmitter
is
now
inducing
signal
approximately up to 20 feet from it, and energizing any conductors
in that field. You may now trace any conductor that has picked up
that signal.
The Broadcast Mode automatically tracks in Null Mode. However,
due to weaker signal inherent in inducing signal, it may sometimes
appear as a peak signal.
Also note, when the user is within 20 feet of the transmitter, you
cannot trace a cable because the signal from the case itself will
overpower the induced cable signal. The user will always hear the
transmitter signal within 20 feet of the transmitter case.
The Broadcast mode does not have a power output adjustment on
the transmitter. To indicate this, the analog needle on the
transmitter normally should read 10 or more. In addition,
remember that ALL conductors in the ground that can pick up the
signal will. Therefore, tracking is better in non-congested areas.
It is important to understand the uses and limitations of Broadcast
Mode when compared to direct connection with the alligator clips.
How to determine depth -
Find the null over the wire path and
mark it. Then place the tip of the receiver on the ground at the
mark. Without lifting the receiver tip from the ground, lower the top
of the receiver to approximately a 45 degree angle and slowly
walk the receiver away from the wire path until you reacquire the
null. The distance between the wire path and the newly
established null is the approximate depth of the target.
Determining target accuracy -
This is a very easy to perform
method of determining target accuracy. Place the tip of the
receiver on the ground directly over your suspected target
location, switch from null to peak by pressing the mode selection
pad. The peak and null responses will agree if the locate is
accurate. If the peak and null are off by more than a few inches
