Sensor calibration
Once the display is setup and before you proceed with calibration ensure all network sources
are selected and confi gured as shown in section 6.
Calibration example:
Depth
A typical transducer installation is through the hull in front of the keel. A datum (off set value)
can be set, such that the depth display refers to either the water line or the base of the keel.
+VE: Positive Datum for Waterline
- VE: Negative Datum for Keel
(0.0)
Setting the depth off set displays depth readings from directly below the keel or propellers of
the boat, or from the waterline to the seabed. This makes it easier to see the available depth,
taking into account the draught of the boat.
The off set value to be entered should represent the distance between the face of the depth
transducer, and the lowest part of the boat below the waterline, or the distance between the
face of the depth transducer and the water surface.
Depth off set value
1 Enter the Settings menu.
2 Select depth via the calibration menu.
3 Select Off set.
4 A dialog box will appear showing the current depth off set value.
¼ Note:
The default value is zero
