4.2.4 Determining the direction of a line
How to proceed Follow the steps below to determine the orientation of a metallic conductor:
Step Action
1 If the direction of the conductor will be determined with the aid of the
Easyloc Tx transmitter, couple the transmitter's signal onto the metallic
conductor in such a way that there is as little signal loss as possible (see
section 4.1.2 Options for direct and inductive signal coupling ) and switch
on the transmitter (see section
4.1.3 Initial use of the transmitter
).
2
Press
to switch on the receiver.
3
Select the desired mode of operation (see section 4.2.2.1 Modes of
operation for the receiver ) by pressing the
button.
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 section 4.2.3 General site surveying ).
5 Rotate the receiver (through its own axis) over this location until the
maximum signal strength is indicated (see section 4.2.2.3 Handling the
receiver
).
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 (see section 4.2.2.2 Regulating the sensitivity level to match
the reception signal strength
). It is advisable to manually adjust the
sensitivity level.
