Parameters
Enter a value slightly greater than the vessel’s maximum emptying rate, in Units (P005) or
percent of Span (P007) per minute.
Measurement Verification (P709 to P713)
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.
The value is automatically altered when Measurement Response Speed (P003) changes.
The higher the value entered, the greater the range of stabilized fluctuation.
