9.3.3.2 Echo conguration (3.3.2)
Near range (3.3.2.1)
Sets minimum distance from sensor reference point, beyond which an echo should be
considered valid.
This is sometimes referred to as blanking or a dead zone.
Setting 0 to 126 m
Default 0m
Far range (3.3.2.2)
Se
ts 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 0 to 126m
Default 32m
9.3.3.3 Echo select (3.3.3)
Algor
ithm (3.3.3.1)
Sets algorithm (applied to the echo prole) to extract the true echo.
Setting First echo F
Largest echo L
Echo area A
Best echo of the r
st and largest echo BLF
Area largest r
st echo ALF
True r
st echo TF
Default First echo F
Echo threshold (3.3.3.2)
Se
ts minimum echo condence. Only echoes above this threshold are evaluated.
Setting -20 to 70
Default 1 to 70
Position detect (3.3.3.3)
Se
ts algorithm used to calculate the position of the echo.
