Parameters
2.4.6. Sampling
Provides a method of checking the reliability of a new echo before accepting it
as the valid reading, based on numbers of samples above or below the
currently selected echo.
2.4.6.1. Echo Lock
Selects the measurement verification process. See Position Detect
(2.4.5.2.) on page 139 for more details.
For radar applications, Material Agitator is the most often used setting, to
avoid agitator blade detection.
2.4.6.2. Sampling Up
Specifies the number of consecutive echoes that must appear above the
echo currently selected, before the measurement is accepted as valid.
2.4.6.3. Sampling Down
Specifies the number of consecutive echoes that must appear below the
