Additional information: The feature will display an
information bar below the numeric presentations on the Graphic
display. The bar provides key technical pararameters related to
the echo sounder operation; frequency, output power and pulse
length. It will also show you the ambient air temperature, the
vessel’s speed and the current depth. If you use the selector pad
to adjust the depth of the VRM (Variable range marker) or the
echo sounder receiver gain, it will show you the current depth
and gain settings while you do this. The default setting is ON.
Depth grid : When this function is enabled, thin horisontal depth
lines will be added to the presentation to easier identify the
depth intervals. Note that this function can also be switched on
and off in the
Echo presentation setup.
Data window sensors : When you have set up the Graphic
display on only a half screen, there is not space for more than
three sensor presentation rectangles at the top of the display.
With this parameter, you can choose if you wish to see sensors
1, 2 and 3 or 4, 5 and 6. When you have set up the Graphic
display on a full screen, this parameter is not visible.
Echo strength colour scale : This parameter allows you to
switch the echo strength colour scale on the left side of the
Graphic display presentation on or off. A turquoise colour
indicates the weakest echoes, while dark red indicates the
strongest echoes. Note that this colour scale can not be enabled
simultanously with the temperature scale.
Time scale : This parameter allows you to switch the time scale
in the Graphic display presentation on or off. When enabled, it
is positioned immediately above the echogram. Note that the
time scale relies on the chosen scroll speed: a low speed results
in a long time scale and vice versa.
Expansion window : The PI44 provides bottom expansion and
zoom functions. When one of these is enabled, you can control
the depth range in the expanded window using this parameter.
To enable the bottom expansion function, press the
B-LCK
button on the keypad. To enable the zoom function, press the
ZOOM button. To disable both, press the STND or SHIFT
buttons. You can also access this parameter in the Echo
presentation setup .
