Right part of the screen
*101 "Measurement/Dummy" is selected by the menu. To confirm the device operation, the dummy displays the ship speed and
the current data of fictitious.
*102 It is necessary to connect the head up bearing sensor such as gyrocompass for the display.
*103 It is necessary to connect the head up bearing sensor such as gyrocompass for the display of the north up bearing standard.
*104The depth of the measurement layer is set with the depth key.
It sets or it is not likely to be able to measure it according to the environmental condition though the depth that can be set
is 500m or less.
*105 For example, E layer is assumed to be a standard layer of drum, and the current (relative current) in A layer seen from
E layer is shown as the AE layer.
The standard layer of drum in a relative current is selected from "Relative current standard: A layer-E layer" by the menu.
*106 The absolute current (A-E layer) is displayed each current direction and speed by the solid line using the direction
and length of the vector.
Display color [A: Green, B: Blue, C: Orange, D: Pink, E: Red]
A relative current (AE layer etc.) displays by the short dashed line using the direction and speed in the vector.
For example, E layer standard, the AE layer is a short dashed line of "Green/red" for the display color , and the BE layer
is displayed in the short dashed line of "Blue/Red".
It is necessary to connect the bearing sensor to display the ship speed/course in the vector. When the bearing sensor
is non-connection, it is fixed in the head up bearing.
*107 Trip/timer is selected by the menu. The numerical value is reset with [RESET] key.
*108 It is necessary to connect the water temperature sensor for the display of the water temperature and the water temperature
graph. The water temperature graph is set by the menu. Refer to 4.1.8.
*109 The depth value is a mean value of depth measured by four each beam.
*110 Ship speed: True ship speed is displayed. Refer to 4.3.1.
Ship speed display: Component /Deflection angle
Course: Due north is assumed to be N and north, south, east, and west (or, 360°) is displayed at the north up bearing setting.
The direction of the prow is assumed to be 0°, and the direction of the course is displayed in the deflection angle at the head up
bearing setting.
*
111 It is necessary to connect the wind direction/speed sensor for the display. It synchronizes with wind direction arrow (
⇒
) in the
current circle graph. Refer to 4.2.1
*112 The depth range is selected from the menu. Gain and STC cannot be adjusted. Refer to 4.2.2
*113 Even if the Reset key of Trip/Timer is operated, the Total Distance cannot be reset. Refer to 7.1.10
