Parameters
P712 Echo Lock Sampling
Sets the number of consecutive echoes appearing above or below the echo currently
locked onto. Sampling ratio must occur before the measurements are validated as the
new reading (for Echo Lock P711 values:
1 or 2 ).
Example Settings:
• P711 = 2: material agitator
• P712 = 5:2
Example Results:
• A new reading will not be validated unless 5 consecutive measurements higher or 2
consecutive measurements lower than the current reading occur.
P713 Echo Lock Window (F = 0.0000)
Adjusts the new measurement changes permitted before the Echo Lock is applied.
The Echo Lock Window is a “distance window” (Units, P005) centered on the echo and
used to derive the reading. When a new measurement is in the window, the window is
re-centered and the new reading calculated. Otherwise, the new measurement is verified
by Echo Lock (P711) before the reading is updated.
Values
Range: 1:1 to 99:99
