Parameters
2.4. Signal Processing
In AMS Device Manager, see the General tab under Signal Processing (LTB)
on page 53.
2.4.1. Near Range
The range in front of the device (measured from the sensor reference point
1)
)
within which any echoes will be ignored. (This is sometimes referred to as
"Blanking" or "Dead Zone".)
2.4.2. Far Range
Allows the material level to drop below Low Calibration Point without
generating a Loss of Echo (LOE) state. See CLEF Range (2.4.5.4.) for an
illustration.
Use this feature if the measured surface can drop below the Low Cal. Point in
normal operation. For more detail see Far Range (2.4.2.) on page 143.
