DISTANCE AND DIRECTION MEASUREMENTS
■
Advanced measurements
1. Move the cursor onto the desired target.
2. Push [EBL1 (VRM1)]/[ ] to display
the EBL1 and VRM1.
L
Push [
t
] or [
u
] to rotate the Electronic Bearing Line.
L
Push [
p
] or [
q
] to increase or decrease the Variable
Range Marker ring size.
3. Push [ENTER]/[ ] to set the VRM/EBL1
setting.
4. Push [EBL2 (VRM2)]/[ ] to display
the EBL2 and VRM2.
•The intersection of the EBL1 and VRM1 becomes the
center of the EBL2 and VRM2.
5. Push [
p
], [
q
], [
t
], or [
u
] to move the cursor onto
the other target.
L
Push [
t
] or [
u
] to rotate the Electronic Bearing Line.
L
Push [
p
] or [
q
] to increase or decrease the Variable
Range Marker ring size.
6. The VRM2 readout displays the distance
between the two targets. The EBL2 readout
displays the direction from one target to the other.
1. Push [TRAILS]/[ ] to turn ON the Trail
function, and then the trail extends until it reaches
to the preset trail time. (p. 12)
•The trail icon and trail interval are displayed in the
upper left of the screen.
2. Push [EBL1 (VRM1)]/[ ] to display
the EBL1 and VRM1, and then set the VRM1 and
EBL1 to a previously plotted target.
L
Push [
t
] or [
u
] to rotate the Electronic Bearing Line.
L
Push [
p
] or [
q
] to increase or decrease the Variable
Range Marker ring size.
3. Push [ENTER]/[ ] to set the VRM/EBL1
setting.
4. Push [EBL2 (VRM2)]/[ ] to display
the EBL2 and VRM2, and then set the VRM2 and
EBL2 to the current plotted position of the same
target.
•The intersection of the EBL1 and VRM1 becomes the
center of the EBL2 and VRM2.
5. The VRM2 is a measure of target movement that
can be converted into relative target speed.
L
For example, when a 6 minute trail time is selected,
multiplying the distance by ten gives the relative
average speed of the target.
L
If your vessel is stationary during the plotting time,
the converted speed and direction become absolute.
L
The converted speed unit is knots, kilometers or
miles, depending on the Distance Unit in the Initial
menu.
6. The EBL2 displays the course direction of the
target.
