3) GRAPHIC DISPLAY
Tide vector: Tide speed and direction for each layer are presented by
length and orientation of a radial vecor bar. Color of vector
bar represents layer. (North-up presentation selectable if
external heading input is available.)
Tide differential vector: Speed and direction of tide differential are presented by
length and orientation of a radial bar. Colors of vector bar
represent the layers involved.
Echo level: Variation of echo strength with depth is presented either in
color sounder mode or in A-scope mode.
(simultaneously for the three sounding beams)
Optional graphic display (display on/off switchable)
Course track plot: Ship's course track display consisting of the last 200 sam-
pling points is presented in ship-centered format. (Display
switchable on/off)
Tide history: Tide vectors recorded at last 24 sampling points are presented
on one screen. (24 hours max.)
Tide effect: Simulated movements of tide layers along the ship's track.
(Display switchable on/off)
Optional text display (available when external data source is connected.)
Water temperature: Water temperature graph covering the 17.5 minutes is dis-
played. (External temperature data input required.)
