How to define sensor offsets

Only the Depth and Spread sensors can have their offset values
adjusted. The purpose is to allow you to compensate for known
deviations.

You may wish to insert a Depth sensor offset to line up the
depth readings from the sensor with those from your echo
sounder. If the echo sounder transducer is located X meters
below the surface, the Depth sensor should have the same offset
value.

Note:

If you have performed a Depth sensor calibration, you will see
than an offset value may already be present. This value has been
provided by the calibration routine.
