Once echo is outside the window, a specified number of consecutive
echoes must appear below the echo locked onto, before measurement is
accepted as valid.
1
(default 0)
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 (see
on page 94 for an illustration).
When the value is 0, the window is automatically calculated after each
measurement.
• For slower Measurement Response values, the window is narrow.
• For faster Measurement Response values, the window becomes
progressively wider.
Note:
The echo lock window is stored as standard sample, but
displayed in the engineering units selected to display level. Any value
entered for the echo lock window will be rounded to the nearest
sample.
