occurs, and the signal gets stronger quite rapidly on either
side of the null. By waving the HOUND 3 back and forth while
slowly moving along the length of the wire, the path of the
null point can be followed between the wires. These wires
can be thought of as being on either side of the open fault .
. . so by using this technique, it will be possible to localize
the area in which the fault occurs.

Reposition the test wires so that they are inline with each
other, with a small gap between them (1/16" to 1/8"). See
Figure 7. Again, trace along the length of the wire and note
how a null point occurs at the gap. This technique can be
used to find the open fairly precisely, if the spacing of the
wires and the location of the open lends its to this approach.
