At the bottom of the SN90 presentation, select a suitable presentation mode, and
activate the Inspection view.
The SN90 offers several
inspection beams. Each
Inspection view presents
one inspection beam. Each
inspection beam has an opening
angle of 6x6° (frequency
dependent). It allows you to
investigate certain targets in
more detail. In the SN90 we use
the phrase echogram to describe
the information provided by the
inspection beams.
Each Inspection view shows
you a selected part of the beam.
If you use several Inspection
views, you can train and tilt
them individually. You can
select the start range (the depth
from which the view starts)
and the range (the "length" of
the transmitted beam) by means
of the
Start Range
• Small labels are shown in the bottom left and right corners of the view. These
labels show you the time in order to identify the scale of the horizontal axis.
• When enabled, equidistant horizontal scale lines are drawn in the view to
indicate the range.
