Setup
in the information pane.
Description
The settings provided by the
Size
Distribution
page allow you to
shape the vertical bars in the
Size
Distribution
information pane
to meet your own requirements.
You can define the upper and
lower limits, the accuracy, and the
vertical resolution.
Note
The measurement accuracy in
the Size Distribution information
pane depends on the vertical angle
of the inspection beam. A beam
that points nearly straight down
corresponds to a traditional echo sounder. This gives the best accuracy since the fish is then
viewed from above. If you use a smaller beam angle, you may see the fish from the front or
back. This gives significantly smaller echoes, and thus low measurement accuracy.
Details
Mode

echo strength value
i dB.
•
Weight
The histogram shows the size distribution as a
weight
in metric units.
