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 h ave 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.
