3.5.2.5.
Smooths jagged peaks in the echo profile. Reforms fragmented echoes into
one echo.

Parame-
ters
Use this feature when monitoring solids, if the reported level fluctuates
slightly even though the monitored surface is still.
Enter the amount of smoothing required. When a value is keyed in, the
nearest acceptable value is entered.
3.5.2.6.
The point on the selected echo from which the measured value is taken.
Options
Note:
the Quick Start Wizard. This provides a more reliable distance measurement
reading for Quick Start applications. (Manually changing the default back to
CENTER can cause a change in the reading.)
3.5.3. Sampling (ECHO SAMP)
3.5.3.1.
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.

Values
3.5.3.2.
Displays the size of the window used for the previous measurement.
Window used is the closest usable window size, depending on the device
measurement resolution.
For example, if window = 1 m, the window used might be 0.96 m.

Window
For slower Measurement Response values, the window is narrow.
For faster Measurement Response values, the window becomes
progressively wider.
