  • Page 58: Calibration

    8.2 Calibration After installation, certain functions in the system must be calibrated to adapt to the physical position and type of sensors installed. All calibration is initiated from the CALIBRATION sub menu. Boat speed The hull shape or the location of the speed sensor may cause incorrect speed readings, and calibration is required to ensure that correct speed and log readings are displayed.
  • Page 59 Calibrate by speed over ground With a GPS connected to the system, the speed may be automatically set identical to the speed over ground value. This adjustment should be made in calm sea with no effect from wind or tidal current. 1.
  • Page 60 Depth The default value for the depth offset is 0.0, which indicates the displayed depth from the transducer to the seabed (b). Refer to the illustration on next page. The value should be increased or decreased, depending on whether the depth reading should be from the water line or from the keel respectively: −...

  • Page 63 Compass calibration Before the compass calibration is started, make sure that there is enough open water around the vessel to make a full turn. The calibration should be done in calm sea conditions and with minimal wind to obtain good results. Use about 60- 90 seconds to make a full circle.
