70%
5 to 95%
The point on the selected echo from which the measured value is taken.
Use this feature if the reported material level fluctuates slightly due to a
variable rise in the leading edge of the true echo on the Echo Profile.
Enter the value (in percent of echo height) to ensure the Echo Lock window
intersects the Echo Profile at the sharpest rising portion of the Echo Profile
representing the true echo. This value is preset to 70%.
