Receiver Modes
Directional Peak
MODE + Directional Peak (DirPk) [SK Toggle]
In DirPk mode, four peak antennas are used to analyze the magnetic field pattern. The
bar graph indicates signal strength and the directional arrows sense the edges of the
magnetic field. The left/right arrows will indicate the direction to the nearest cable that is
in-line with the receiver handle.
As the antenna crosses the cable or pipe, the receiver speaker volume increases to a
maximum, the bar graph [1l] fills from both sides toward the middle, and the numeric
signal strength [10] increases. As the antenna moves off the target path, the speaker
volume decreases and the bar graph opens. Use the bar graph and the numeric signal
indicator to locate the exact target path.
Left of Target Path Directly Over Target Path
Right of Target Path
Once the target path has been located, the arrows at the top of the screen will indicate
the location of the target path in relationship to the receiver.
Note: When field distortion (due to congestion) is affecting the receiver the left/right
arrows may not coincide with the bar graph. Use the maximum numerical signal
strength to target the cable or pipe.
Directional Null
MODE + (DirNull) [SK Toggle]
In DirNull mode, as the operator approaches the cable or pipe, the numerical signal will
increase then fall sharply as the receiver crosses the target cable or pipe. The bar graph
fills from both sides toward the middle and the receiver speaker volume decreases. As
the antenna moves off the target path, the bar graph opens, the signal strength increases,
and the speaker volume increases. Gain adjust is automatic in DirNull mode.
The center of the DirNull screen provides a ‘compass view' of the target path. An arrow
will point toward the location of the cable/pipe in 45-degree steps. A solid line will
appear over the cable/pipe, indicating its orientation to the receiver handle.
