D: Technical Reference
CLEF Range (2.4.5.4.)
Determines the level below which the CLEF algorithm will be used. Above this level the
Center algorithm is used when Hybrid is selected in Position Detect (2.4.5.2.).
CLEF Range is referenced from Far Range.96
Echo Threshold (2.4.5.3.)
Confidence (2.4.7.1.) describes the quality of an echo. Higher values represent higher
quality. Echo Threshold defines the minimum confidence value required for an echo to be
accepted as valid and evaluated.
Echo Lock (2.4.6.1.)
If the echo selected by Algorithm is within the Echo Lock window, the window is centered
about the echo, which is used to derive the measurement. In radar applications, two
measurement verification options are used:
Lock Off
SITRANS LR560 responds immediately to a new selected echo (within the restrictions set
by the Maximum Fill / Empty Rate), but measurement reliability is affected.
Material Agitator
A new measurement outside the Echo Lock Window must meet the sampling criteria
before the window will move to include it.
The other available options, Maximum Verification and Total Lock are not recommended
for radar.
