Depth calibration

This adjustment only applies to “smart” depth transducers

that outputs depth on NMEA2000 format.

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:

- A negative offset equal to the vertical distance

from the transducer to the keel will display the

depth as measured from the keel (a)

- A positive offset equal to the vertical distance

from the transducer to the water line will

display the depth as measured from the water

line (c)
