3.5.2.4. Narrow Echo Filter (default 0)
Filters out echoes of a specific width.
To remove a false echo from the Echo Profile, take its width in mm and
multiply it by 0.014. Enter the result.
For example, to filter out a spike with 500 mm width enter 7 (the sum of 500
x 0.014).
When a value is keyed in, the nearest acceptable value is entered.

When a value is keyed in, the nearest acceptable value is entered.
3.5.2.5. Reform Echo (default 0)
Smooths jagged peaks in the echo profile. Reforms fragmented echoes
into one echo.

3.5.3. Echo Sampling
3.5.3.1. Window.
A "distance window" centered on the echo, used to derive the reading.
When a new measurement is in the window, the window is re-centered
and the reading is calculated .
When the value is 0, the window is automatically calculated after each
measurement.
