The Echogram view provides echo data from a horizontal beam in a common echogram
presentation. The echo data is taken from the current bearing and tilt. The beam used
to provide data is identified in the top left corner of the view. Horizontal dotted lines
show the depth intervals.
• You can change the bearing on the
Main
menu. You can also select the bearing line
in a Horizontal view and drag it sideways.
• You can change the tilt angle by means of the
Tilt
function on the
Main
menu. You
can also click on the tilt line in a Vertical view and drag it up and down.
Left-click in the Echogram view to open the tooltip. The tooltip provides the cursor
location in the echogram (slant range, true range and depth) as well as the current
pulse duration and time.
The
Horizontal Scroll
function controls how fast the echo presentation shall move from
right towards left in the Echogram and Inspection views. The speed is controlled by
adjusting the number of pixels used to present each ping. A higher speed will update
the view faster, but will also reduce the resolution.
6 At the bottom of the display presentation, select a suitable presentation mode, and
activate the
Plane view.
The Plane view presents the echo data in a horizontal sector ("fan"). The sector
direction can be changed in both vertical and horizontal directions. The tilt is drawn
in the
Vertical and Horizontal views as two dotted lines. The same dotted lines are
shown in the Horizontal view as a dedicated bearing line to visualize the direction
of the plane beam.
• You can change the bearing on the
Main
menu. You can also click on the dedicated
dotted bearing line in a Horizontal view and drag it.
• You can change the tilt angle by means of the
Tilt
function on the
Main
menu.
The
Horizontal Tx Sector
function defines the opening angle of the sector.
• The selected range is divided into identical distances.
• The distance and depth of the cursor location is shown in the lower right corner of
the view.
• The current settings for range, gain and tilt are show in the lower left corner of
the view.
