Measurement Verification Parameters (P710 To P713) - Siemens sitrans LU10 Instruction Manual

Measurement Verification Parameters (P710 to
P713)
P710 FUZZ FILTER
Use this feature to stabilize the reported material level, due to material 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. (See
The higher the value entered, the greater the fluctuation stabilized. (0 = off)
values: 0 to 100
P711 ECHO LOCK
Use this feature to select the measurement verification process.
This value is automatically altered when Material (P002) and / or Measurement
Response (P003) is altered. (See Measurement Response).
When set for "maximum 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 SITRANS LU10
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 SITRANS LU10 responds immediately to a new
measurement as restricted by the Max Fill / Empty Rate (P700 / P701); however,
measurement reliability is affected.
