2.6.8 mA Output Value: Allows you to view the simulated value to test the functioning of the loop. Read Only
2.7 Signal Processing
2.7.1 Near Range: The range in front of the device (measured from the sensor reference point) within which any
echoes will be ignored. This is sometimes referred to as blanking or a dead zone.
Value Range: 0 to 105 m (0 to 344.5 ft); Default 0.278 m (0.91 ft)
2.7.2 Far Range: Allows the material level to drop below Low Calibration Point without generating a Loss of Echo
(LOE) state. Far Range can extend beyond the bottom of the vessel. Use this feature if the measured surface can
drop below the Low Cal. Point in normal operation.
Values: Range Min = Low Calibration Point
Max = 105 m (344 ft)
Default: Value for Low Calibration Point + 5 m (16.4 ft)
2.7.3 Echo Select
2 .7.3.1 Algorithm: Selects the algorithm to be applied to the echo profile to extract the true echo.
ALF Area Largest First
A Echo Area
L Largest Echo
F First Echo; Default
AL Echo Area Largest
AF Echo Area First
LF Echo Largest First
BLF Best of First and Largest Echo
BL Best Largest Echo
BF Best First Echo
LAST
TF True First Echo
2.4.3.2 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 Fail-safe (LOE) timer. When Confidence (2.7.6.1) exceeds Echo .......
Threshold (2.7.3.2) the echo is accepted as a valid echo and is evaluated. Use this feature when an incorrect
material level is reported.
Value Range: 0 to 99; Default 5
2.7.3.3 Position Detect: Selecting Steel or Concrete vessel type in the Quick Start Wizard changes the settings for
Position Detect (2.7.3.3) to Rising Edge. Defines where on the echo the distance measurement is determined. See
Shaper Mode (2.8.4) for more details. If the vessel bottom is being reported as the level instead of the actual
material level (at low conditions), we recommend setting Position to Hybrid using it in combination with CLEF
Range (2.7.3.4)
RISING (yields highest stability on sloped targets); Default
CENTER (yields higher accuracy on flat, non-sloped targets
HYBRID (CENTER and CLEF)
CLEF (Constrained Leading Edge Fit)
