described.
7.22.1
P709 Damping filter
Stabilizes the reported level within the Echo Lock Window (P713) in the event of level
fluctuations (for example, a rippling or splashing liquid surface). The value is in seconds, and
depends on the number of seconds it takes the device to reach 63% of a step value change
in reading.

P007 Span
P713 Echo lock window
The value is automatically altered when Measurement Response Speed (P003) changes.
The higher the value entered, the greater the range of stabilized fluctuation.

P711 Echo lock
Note
Ensure the agitator is always running while SITRANS Probe LR is monitoring the vessel, to
avoid stationary blade detection.
