7 DETERMINING THE DIRECTION OF A LINE
Follow the steps below to determine the orientation of a metallic conductor:
Step Action
1.
If the direction of the conductor is to be determined with the aid of the transmitter,
couple the transmitter's signal to the metallic conductor in such a way that there is as
little signal loss as possible and switch on the transmitter.
2.
Switch on the receiver.
3.
Select the desired operating mode by pressing button # 3.
The symbol for the currently selected operating mode is shown in the lower right-hand
corner of the display.
4.
Hold the receiver perpendicular to the position of a known metallic conductor, e.g.
above a location which was marked during the probing of the site.
5.
Rotate the receiver (through its own axis) over this location until the maximum signal
strength is indicated.
Result: The receiver is in line with the conductor when it is positioned where the signal
is strongest, which is prerequisite for determining the direction of the line.
6
To determine the path over an extended distance, proceed by moving forward while
maintaining the maximum signal strength. If the signal becomes weaker, check that the
conductor has not changed direction or become deeper; move and/or rotate the
receiver to the left and right until the maximum signal strength is detected again.
Adjust the sensitivity of the receiver as needed if the signal level is too strong or too
weak. It is advisable to adjust the sensitivity level manually.
The path of the metallic conductor should always be followed until it exits the site being
searched, and its path should be clearly marked along the way with paint/chalk or
marker flags.
