Locating the line
If a line does not have to be traced the entire way from the connection point but instead
only a certain section of the line needs to be detected, the line must first be located in
this area and its orientation determined.
It basically does not matter whether the line that is being searched for is an actively
transmitting line or a line with a passive signal frequency (e.g. a live power cable) – the
basic locating of the line and the determining of the line direction basically function in the
same way.
Once the measurement settings have been set (see page 45) in accordance with the
signal to be located, the area of the expected line path must first be paced off and
examined for a significant level deflection. The maximum method is particularly suitable
for this general locating of the line, since this also provides a signal response at quite a
distance from the line. However, with very deep lines the super maximum method may
be the better option.
A good indication of the fact that a sufficiently strong signal level is being received from
the line being searched for is the green line that is shown on the display indicating the
supposed path of the line. If this no longer arbitrarily jumps back and forth but remains
on one orientation and reacts plausibly to the rotary movements of the receiver, the line
path has been reliably measured by the receiver.
In the first step, the receiver should now only be rotated around its own axis until the
green line runs vertically in the display, and the receiver is lateral to the expected path of
the line accordingly.
