I.5.2.1.2 Miscellaneous Fields in ‘More Options'
At the bottom of the expanded dialog box are three fields: Triggers, Beams to
Display
, and Pings per second. Each is explained next.
•
Triggers: This field keeps a running total of the number of triggers received
from the sonar.
•
Beams to Display: The Klein 5000 sonar adjusts this number automatically
depending on a number of variables, including speed, range scale and
resolution. The first number indicates the number of beams currently being
displayed and saved. The second number (in brackets) is the number of
available beams. The maximum number for both is 5. If a combination of the
above variables calls for more than 5 beams, the following message appears:
5+ Too fast! (5)
At this point, side scan data coverage along track is not optimal. Generally, it will be
necessary to slow down the vessel until the message disappears. See the Klein 5000
manual for more detail on this subject.
•
Pings per second: This field displays the current sonar ping rate. This number
will increase with speed, shorter ranges, and higher resolution.
I.5.2.2 Some Guidelines for Speed, Range and Resolution
The Klein 5000 is an advanced sidescan sonar that can maintain a constant along-track
resolution for a range of different vessel speeds. At the normal resolution (20 cm) setting
the maximum speed is around 10 knots before along track resolution becomes less than
20 cm. At the high resolution (10 cm) setting the maximum speed is around 5 knots
before the along-track resolution becomes less than 10 cm. See the Klein 5000 manual
for more details.
I.5.2.3 ‘Advanced Setup and Diagnostics’ in Server for Klein 5000
The Isis Server for Klein 5000 dialog box also has an Advanced Setup and
Diagnostics
button. Clicking it opens the Klein 5000 Advanced Settings dialog box
