The Echo Lock Window is a distance window [Units (2.1.1.) (Page 162) ] centered on the
echo and used to derive the Reading. When a new measurement is in the window, it is re-
centered and the new reading calculated. Otherwise, the new measurement is verified by
Echo Lock (2.11.5.4.) (Page 235) before the reading is updated.
When 0 is entered, the window is automatically calculated after each measurement. For
slower Response Rate (2.3.4.) (Page 174) values, the window is narrow; for faster Response
Rate (2.3.4.) (Page 174) values, the window becomes wider.
Fuzz filter (2.11.5.6.)
Stabilizes the reported level, due to level fluctuations (such as a rippling or splashing liquid
surface) within the Echo Lock Window (2.11.5.5.) (Page 235).

This value [in % of Span (2.2.2.) (Page 169)] is automatically altered when Response Rate
(2.3.4.) (Page 174) is changed. The higher the value entered, the greater the fluctuation
stabilized.
