[II] Vector Length: VECTOR TIME
The vector length of a target is proportional to its speed, and the vector time can be
changed from 1 to 60 minutes.
The figure below illustrates a vector length of a target of six minutes. The tip of the vector
represents the target’s expected position in six minutes.
Setting Vector Time
In order to display the relative vector, press the [TRUE/REL] key to select it.
1 Click the numeric section
of
“VECTOR”.
The numeric input dialogue box is
opened.
2 When changing vector constants, left-click the numbers 0 to 9
or the “+” or “−” keys to change the vectors.
3 Click ENT .
The number input will be applied as the vector time.
