MEASUREMENT VERIFICATION PARAMETERS (P710 to P713)
P710 FUZZ FILTER
Use this feature to stabilize the reported level, due to level fluctuations (such
as a rippling or splashing liquid surface), within the Echo Lock Window (P713).
This value (in % of Span, P007) is automatically altered when Measurement
Response (P003) is altered.
The higher the value entered, the greater the fluctuation stabilized.
values: 0 to 100 (0 = off)
P711 ECHO LOCK
Use this feature to select the measurement verification process.
If a
material agitator
(mixer) is used in the vessel monitored, set Echo Lock
for "maximum verification" or "material agitator", to avoid agitator blade
detection. Ensure the agitator is always "on" while the HYDRO+ is monitoring
the vessel, to avoid stationary blade detection.
When set for "max verification 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 HYDRO+
continuously searches for the best echo according to the algorithm chosen
(P820). If the selected echo is within the window, the window is then centered
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 "off", the HYDRO+ 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 = maximum verification
2 = material agitator
3 = total lock
