Section 4 Range and Bearing Measurement Methods 4-16
4.6.3 Setting all the parallel index lines concurrently
(All mode)
When the operation mode is set to [All], all the parallel index lines are operated concurrently. All the
lines are in parallel.
1
Select [All] from the [Mode] combo box.
2
Enter a direction of the parallel index lines in [PI Bearing] (parallel index line bearing).
The setting is applied to the bearings of all the parallel index lines.
Memo
The bearing can also be adjusted by turning the [EBL] dial clockwise/counterclockwise.
When the dial is turned clockwise, the bearing is adjusted in the plus direction, and when
the dial is turned counterclockwise, the bearing is adjusted in the minus direction.
The set value is displayed in the input box.
3
Enter a display interval of the parallel index lines in 09. [Interval].
The setting is applied to all the lines.
The input range is the PPI radius when PPI is used as the centre for the lines and double the PPI
radius when the PPI is not used as the centre.
Memo
The interval can also be adjusted by turning the [VRM] dial clockwise or anti-clockwise. If
the dial is turned clockwise, the interval value increases and if the dial is turned
anti-clockwise, the interval value decreases.
The set value is displayed in the input box.
Whenever the unit display switching button on the right side of [Interval] is clicked on, the unit
(NM/km/sm) of the value displayed is switched.
Memo
NM denotes nautical mile, sm denotes statute mile, and km denotes kilometre.
4
Select the area for displaying the parallel index line from the [Operation Area] combo
box.
When [One Side] is selected, 8 parallel index lines are displayed on one side of the reference
point of own ship or the point set arbitrarily.
When [Both Side] is selected, 15 parallel index lines are displayed on both sides of the reference
point of own ship or the point set arbitrarily.
