Range Setting
The [Range Setting] is used to limit the algorithm area and does not refer to the distal
measurement limit of the instrument. Please refer to the technical specifications section for the
measurement limits of the instrument. The algorithm will ignore echoes outside the range, so a
reasonable range setting will avoid multiple reflections and possible out-of-range interference.
The range should be 1-2m greater than the actual tank height, especially for tanks with a conical
bottom, to obtain a full echo.

[False Echo Learning]
[False Echo Learning] learns false echoes from containers containing known obstacles and
forms a screening curve for background noise (threshold curve TVT). This option contains two
levels of guidance menus, [False Echo Mode] and [False Echo Region]. The [False echo mode]
can be selected in three ways: (1) Full means that the false echo learning is performed within the
default full range of the instrument (2) Select area means that the false echo learning is only
done within the set area (3) Exclude area means that the false echo learning is only done outside
the set area. After selecting "Select Area" or "Exclude Area", you need to further enter the area
"Start" and "End" points. The menu is displayed as shown below:
