3. SYSTEM SETTINGS AFTER INSTALLATION
Compensation
1. Click Compensation in the System menu to show the Compensation dialog box is
displayed.
Ten key button
2. Set the following items. To enter numeric values, press the ten-key button at lower
left-hand side to open the ten-key panel. Click appropriate numeric keys.
Stabilization: Choose ON to activate the stabilization function.
Heaving: Choose ON to enable the heaving correction function. The satellite compass
is required to connect.
Sound velocity: Compensate the sound speed if the depth indicated on the screen is
different from the usual depth indication for the area. (Setting range: 1400 to 1600 m/s)
Draft: Set the ship's draft if you want to display the depth from sea surface to seabed
rather than from the transducer. (Setting range: -6.0 to +60.0 m)
Roll offset: Compensate the roll angle error of the motion sensor. Set positive values
when the starboard is up. (Setting range: -10.0 to +10.0 degrees)
Pitch offset: Compensate the pitch angle error of the motion sensor. Set positive values
when the bow is up. (Setting range: -10.0 to +10.0 degrees)
• Note that the satellite compass has its own roll and pitch corrections. Enter
compensations here or at the satellite compass; do not compensate at both.
Motion sensor: Choose the internal sensor or SC (Satellite Compass) for stabilization.
SC-TD in longitudinal dir: Set the longitudinal distance from satellite compass antenna
(SC) to transducer (TD). If the TD is bow side, set positive values. (Setting range: -100.0
to +100.0 m)
SC-TD in port/stbd dir: Set the transverse distance from SC to TD. If the TD is
starboard side, set positive values. (Setting range: -100.0 to +100.0 m)
SC-TD in up/down dir: Set a vertical distance from TD to SC, in positive values.
(Setting range: -100.0 to +100.0 m)
Internal sensor in bow dir: If so equipped, correct installation angle error of the internal
motion sensor, i.e., the transceiver unit. If the transceiver unit is installed with its front
panel facing to the port side exactly, the motion sensor faces the bow at zero degrees. If
installed panel facing to the bow, enter 90. (Setting range: 0 to 360 degrees)
• Inscribe this setting value on the NOTE label on the front panel of the transceiver
unit.
