Measurement Verification Parameters (P710 To P713) - Siemens interranger DPS300 Instructional Manual

P707 (V) Rate Value
View the rate of sludge level change (in Units (P005) or % of Span (P007) per
minute).
(A negative rate indicates the clarifier is emptying).
This is the value displayed when is pressed in the RUN mode.
Values:

Measurement Verification Parameters (P710 to P713)

P710 Fuzz Filter
Use this feature to stabilize the reported sludge level, due to level fluctuations
(such as a rippling surface), within the Echo Lock Window (P713).
The value is in % of Span. The higher the value entered, the greater the
fluctuation stabilized. (0 = off)
Values:
P711 Echo Lock
Use this feature to determine how quickly the DPS300 locks onto a new echo.
The value is automatically altered when Material (P002) is altered.
When set for "skimmer" or "material agitator", a new measurement outside of the
Echo Lock Window (P713) must meet the sampling criterion (P712).
For "total lock", Echo Lock Window (P713) is preset to "0". The DPS300
continuously searches for the best echo according to the algorithm chosen (P820).
If the selected echo is within the window, the window is then centred about the
echo. If not, the window widens with each successive shot until the selected echo
is within the window. The window then returns to its normal width.
When Echo Lock is turned "off" the DPS300 responds immediately to a new
measurement as restricted by the Max Fill / Empty Rate (P700/P701), however
measurement reliability is affected.
Values:
0 = off
1 = skimmer
2 = material agitator
3 = total lock
P712 Echo Lock Sampling
Use this parameter to specify the number of echos required to move the current
level value outside of the Echo Lock Window.
The two values, represented as x.y are for echos above and below the current
Echo Lock Window, respectively.
