Environment
Environmental parameters such as salinity, sound speed and water temperature all
play an important part to present accurate echo data. Use the
Environment
parameters
to define these values. Depending on the current sea and weather conditions, you may
need to change these values frequently.
•
Language
You may prefer to use the SN90 with a user interface in your own language. A
selection of languages is provided. The
Language
function allows you to select the
language to be used in the SN90 presentations, menus and dialog boxes.
•
Fish Select
The Size Distribution information pane shows a histogram of the echoes detected
from single fishes. The calculations are based on the fact that different fish species
have different echo strength. The echo strength also depends on the operating
frequency you use. For various reasons, the fish size presented in the
Size Distribution
information pane may be inaccurate. The
Fish Select
dialog box allows you to select
the fish species you expect to catch, and manually adjust the size distribution.
•
Stabilization
A hull unit may be provided as an optional method to lower and hoist the transducer.
A motion sensor for electronic stabilization of the sonar beams is provided as a part of
the hull unit. In case of a faulty motion reference unit this functionality can be turned
Off . A suitable external sensor must then be used.
•
Screen Captures
While using the SN90 you may wish to make a screen capture to save an instantaneous
copy of the current presentation. You can choose either a single screen capture or a
sequence with multiple screen captures.
•
Beam Visualization
With the various beams provided by the SN90, it may be difficult to understand
the concept. How do these beams "behave" in the water? By means of a graphic
presentation, the
Beam Visualization
dialog box attempts to give you a better
understanding of how the acoustic beams are transmitted into the water.
•
BITE (Built-In Test Equipment)
The
BITE
(Built-In Test Equipment) dialog box controls the test and diagnose
program that checks the performance of the SN90.
