3. Select [7 Density Calculations], then left-click.
4. Select the coefficient setting number ([2 Coeffi-
cient Setting1] to [5 Coefficient Setting4]), then
left-click.
The pop-up window shown to the right appears.
The X-axis indicates the echo strength (level)
and the Y-axis indicates the coefficient setting.
The information is used to estimate the volume
of schools of fish from echo strength and is ad-
justable. This allows you to compensate the es-
timated volume of schools of fish versus actual
volume. The value obtained by multiplying the
value for each echo intensity specified in the
graph by the value set in [Magnification] is the
conversion factor (unit: t/1,000,000m
3
).
