DISTANCE AND DIRECTION MEASUREMENTS

■

Advanced measurements

Using both Electronic Bearing Lines (EBL) and both Variable Range Markers (VRM), the following advanced mea-
surements can be made:

• Measuring the distance and direction between 2

targets

Push

[

]

to move the cross line cursor

on the desired target.

Push [EBL1 (VRM1)] to display the EBL1 and
VRM1.

Push

[

]

to move the cross line cursor

on the next target.

Push [EBL2 (VRM2)] to display the EBL2 and
VRM2.

Push [EBL2 (VRM2)] once more to display the
EBL2 and VRM2.

• The intersection of the EBL1 and VRM1 becomes the

center of the EBL2 and VRM2.

The VRM2 readout shows the distance between the
two targets. The EBL2 readout shows the direction
from one target to the other.

• Measuring the relative speed and course of a

target

Push [TRAILS] (p. 12) ON; then wait until the trail
time count up reaches to the TRAIL TIME.

Set VRM1 and EBL1 to a previously plotted target
as described above.

Set VRM2 and EBL2 to the current plotted position
of the same target as described as above.

The VRM2 readout is a measurement of target
movement which can be converted into relative tar-
get speed.

• For example, when a 6 min. trail time is selected, multi-

plying the distance by ten gives the relative average
speed of the target.

• If your ship is stationary during the plotting time, the

converted speed and direction become absolute.

• The converted speed unit is knots or kilometres/hour

when the selected unit in the “FUNCTION” menu is
nautical miles (NM) or kilometres (KM), respectively.

The EBL2 readout shows the course direction of
the target.
