Gain Control, Trim and Light Level Indicator
Items 2 and 8 represent the thruster gain control settings. V (2) indicates the Vertical thrust
settin
g 1=10%, 2=20%, 3=30%…0=100%. H (8) indicates the Horizontal thrust setting.
Next to the vertical gain setting is the indicator for the Trim function and light level indicator
(3). If nothing is displayed, the Trim is off and the light is off. When Trim is on, the display
will read TRM. If the light is on and trim is not on, the light level indicator will display the
intensity of the light. L1 being 10% up to L10 which is 100%. If both Trim and the light are
on, the display will alternate between the two.
2.2.3
Depth and Heading
Heading is displayed at the top middle of the Video Overlay (4). The three digits illustrate
the 360 degrees of a compass heading. To the right of heading is a + or a -, followed by a
numerical digit. This is the turns counter (5) which represents the number of turns the LBV
makes in one direction of 360º. + indicates turns in the clockwise direction.
– indicates
turns in the counter clockwise direction. This is a valuable tool which allows the operator to
keep track of the turns placed in the tether. The operator should reverse these turns (at
depth) before recovery of the LBV in order to facilitate coiling of the tether and to prevent
damage to the fiber optic line.
Below the heading information is depth (10). Depth can be displayed in meters sea water
(msw), meters fresh water (mfw), feet sea water (fsw) or feet fresh water (ffw). To change
the display and calibrate, see the Menu section 2.3. These units of measurement are
selectable by the operator in the Setup Menu (section 2.3.3).
A “*” will appear next to the heading or depth if the corresponding Auto function is on.
2.2.4
Camera Angle and Temperature
To the right of heading is the camera angle Indicator (6). 0 indicates that the camera is
facing 0º with respect to the horizon. A reading of +90 indicates that the camera is pointing
straight up and one of
–90 indicates that the camera is pointing straight down. The value
displayed always represents the camera currently being used.
