Parameters
2.2.3.1.2. Echo Threshold
Sets the minimum echo confidence that the echo must meet in order
to prevent a Loss of Echo condition and the expiration of the LOE
timer. When Echo Confidence (2.2.3.6.1.) exceeds the Echo Threshold
(2.2.3.1.2.), the echo is accepted as a valid echo and evaluated.
Use this feature when an incorrect material level is reported.
2.2.3.1.3. Position
Defines where on the echo the distance measurement is determined.
(See Echo Position Detection on page 104 for more detail.)
2.2.3.1.4. Echo Marker
The point on the selected echo from which the measured value is
taken.
When SITRANS LR260 is using Rising Edge, higher values will cause
lower level readings and lower values will cause higher level
readings.
