The output is scaled linear from minimum to maxi-

If your sensor height doesn't match your vessel height
it is possible move the minimum level and maximum
level beyond the physical sensor by adjusting the off-
set value in the HB-tool. It is also possible to make the
offset by making a calibrations to known levels also in
