1.26 Electronic Plotting (E-plot)
10 operator-selected targets can be plotted elec-
tronically to assess their motion trends. Five past
positions are marked for each plotted target.
A vector appears as you enter a second plot for a
target and is updated each time a new plot is en-
tered for the target. The vector shows the target
motion trend based on its latest two plots.
Alphanumeric readouts for last-plotted or selected
target appear at the bottom of the display.
It should be noted that the vector and alphanu-
meric target data are not updated in real time, but
only when you enter a new plot.
E-plot requires ship's speed input (automatic or
manual) and a compass signal.
When speed is input by a navigator, own ship
moves in accordance with course; not heading.
Plotting a target
Before plotting a target, select PLOT or ALL on
the MARK & DATA DSP menu.
1) Place the cursor on the target you want to plot,
and press the PLOT SYMBOL key.
2) Watching the E-plot timer on the PLOT mode,
wait at least 30 seconds. Place the cursor on
the plot symbol and press the ENTER/SE-
LECT key. The plot symbol of the target
flashes.
3) While the plot symbol of the target is flash-
ing, place the cursor on the target again and
press the PLOT SYMBOL key. The plot sym-
bol shifts to the new target position and the
previous position is marked by a small dot.
