4.3.3 Determining the direction of a line
Step Action
1
If the direction of the conductor will be determined with the aid of the
TX5000 transmitter, couple the transmitter's signal onto the metallic
conductor in such a way that there is as little signal loss as possible
(see paragraph 4.2.2 and paragraph 4.3.1)
2
Press to switch on the receiver
3
Select the desired mode of operation by pressing the key (see
paragraph 4.3.1). The symbol for the currently selected mode of
operation 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 (see paragraph 4.3.2)
Rotate the receiver (through its own axis) over this location until the
maximum signal strength is indicated (see paragraph 4.3.1.2)
5
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.
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
Adjust the sensitivity of the receiver as needed if the signal level is
too strong / weak. It is advisable to manually adjust the sensitivity
level (see paragraph 4.3.1.1)
