OPERATION IN THE FIELDOPERATION IN THE FIELD
1. PEAK MODE
In the Peak Mode, the pipeline location is
indicated by the “rising pyramid” bar graph,
by the numerical display directly below it,
and an increase in sound output.
The “rising pyramid” bar graph increases
as the Receiver is moved closer to the
pipeline from either side. If there is no “rising
pyramid,” increase the sensitivity using the
Up Arrow key. When the “rising pyramid”
reaches a maximum, the Receiver is directly
over the pipeline.
The numerical display beneath the “rising
pyramid” and the audio sounds are also
indications of the strength of the signal.
Both are also at their maximums when the
Receiver is directly over the pipeline. Often,
small changes in the numbers displayed or
in the audio are easier to detect than small
changes in the height of the pyramid.
2. NULL MODE
a) Hold the Receiver directly over the
pipeline and facing in the direction of
the pipeline. Adjust the sensitivity with
the Sensitivity Up/Down Arrows until the
sensitivity level (upper right corner of
display) is about 30.
b) Adjust the sound level with the Sound
Volume Control Key to a level easily
heard by the user. The sound volume
cycles through 4 levels.
c) As the Receiver is moved closer to the
pipeline from either side, the sound level
decreases. Directly over the pipeline,
the sound level is at its minimum, and
the small gure jumps from one side of
the pipe to the other very quickly. This
minimum point is the “Null” location.
NOTE: There is no depth measurement
function in the Null Mode.
