Trawl info setup
These settings are used to set up the PI44 parameters related to
the trawl presentations on the
Graphic display
. When enabled,
marker lines providing trawl depth information will be
superimposed on the display.
The marker lines are enabled in the
Marker line setup
.
To access the parameters, press the
ADJ
(Adjust) button when
you have a
Graphic display
in the active window. Then, press
the
GAIN+
button until the parameters appear. You can also
press the
MENU
button to access the
Echo quick menu
, and
then select
Graphic setup
(8).
Headrope sensor:
This setting defines which sensor that is
placed on the headrope.
Footrope sensor:
This setting defines which sensor that is
placed on the footrope.
Trawl opening mode:
This parameter decides how the trawl
opening shall be recreated on the
Graphic Display
. If you have
sufficient sensors on the trawl you must select
Auto
, and the the
PI44 will automatically calculate the trawl opening and draw it
accordingly. If you only have one sensor on the trawl opening
(Depth or Height sensor on the headrope), the
Manual
setting
will add an artificial line on the
Graphic Display
. The distance
from the headrope to the footrope must then be defined
manually using the
Manual trawl marker
parameter (below).
Manual trawl marker:
Set the manual trawl opening height for
use with the
Trawl opening mode
parameter (above).
Clump sensor:
This setting defines which sensor that is placed
on the clump.
