Graphic setup
These settings are used to set up the PI54 parameters related to
the Graphic display.
The Graphic display shows the data from the sensors in their
alphanumerical presentations, as well as historical plots
sumperimposed on the echogram. The digits in the
alphanumerical presentations are black when the data are valid,
they are grey when the values are only predicted, or they are
replaced with asterix characters (*) when the contact with the
sensor is lost. The yellow pulse lamp is lit every time
information in received back from the sensor. The positioning of
the alphanumerical presentations is controlled by the order of
which the sensors were configured in the Sensor setup
dialogue.
To access the parameters, press the ADJ button when you have
a graphic display in the active window. You can also press the
MENU button to access the Echo quick menu, and then select
Graphic setup.
Superimpose echo sounder: When activated, the presentation
from the echo sounder is added to the graphic display. Note that
this option is only valid if you have the echo sounder
transducer(s) installed, and the echo sounder is set up for normal
operation. You can only switch this function on or off.
Scroll speed: This function controls how fast the presentation
shall scroll from right to left across the display. By defining this
speed you also control the time scale. If you slow down the
scroll speed, you will also increase the time between each echo
sounder transmission (ping). If you choose FREEZE the
presentation (and also the echo sounder transmissions) will stop
altogether. Note that this parameter can also be set in the Echo
pres entation setup.
