Defines the range of 2.11.3.2. Auto False Echo Suppression to use for
ignoring false echoes. (See also 2.1.1. Units on page 122.)
Range: 0.000 to 15 m (50 ft)
Values
Preset: 1.000 m (3.28 ft)
Determine the actual distance from the transducer face to the
material surface. Subtract 0.5 m from this distance, and enter the
result.
Set up (perform this function when vessel is empty or nearly
empty):
Step 1. Determine actual distance from transducer face to
material level.
Step 2. Enter the distance to material surface minus 0.5 m in to

Distance (meters)
Defines (in percent) how high the TVT curve is placed above the
profile, relative to the largest echo. When the HydroRanger is located
in the center of the vessel, lower this parameter to prevent multiple
echo detections.
