Chart/Plot View - Interphase Twinscope Operation Manual

Chart/Plot View

(split screen)
In this view, the Twinscope shows a split screen display
with a conventional down looking depth sounder picture
on the left and a track plot display on the right. Pressing
the "GO" soft key will bring up a sub-menu to allow
adjustments to the track plotter display. Adjustments to
the left side of the display are not possible in this view.
To make adjustments to the depth ranges, alarms, etc., go
to the CHART view.
From the Command Center select the PLOT/CHART
view and press the "GO" soft key to bring up the menu
showing the features and adjustments for this view.
Range
The "RANGE" soft key calls up the sub-menu which lets
you turn on and off an automatic plot ranging function by
pressing the soft key labeled "TRACK". This feature
will, for example, automatically increase the track plot
range if your position goes off the screen. You can
manually adjust the plotter range by using the Range up/
down soft keys in this sub-menu.
The Track Plot square on the display shows the current
plotter range (1/4, 1/2, 1, 2, 4, 8, 16, 32, 64, 128) in
statute (U.S.) or nautical miles depending on your units of
measure selected.
Mark
Pressing the "MARK" soft key allows you to mark your
current position on the track plot screen with one of three
graphic icons - an anchor, a fish or a flag. You may use
each icon up to ten times on a track plot for a total of up
to 30 possible marks. All Marks are lost when the unit is
turned off.
