considered valid.
This is sometimes referred to as blanking or a dead zone.
Setting
Default
Far range (3.3.2.2)
Sets maximum distance from sensor reference point, within which an echo should be
considered valid.
Use this feature if the measured surface can drop below the lower calibration point in normal
operation.
Setting
Default
9.3.3.3

Echo select (3.3.3)

Algorithm (3.3.3.1)
