Parameters
2.2.1.8. Limit Sensor Value
When On, limits the sensor value to the range between Low Calibration Point
and High Calibration Point.
2.2.1.12. Near Range
The range in front of the device (measured from the sensor reference point)
within which any echoes will be ignored, defined in sensor units. This is
sometimes referred to as blanking or a dead zone. The factory setting is
50 mm past the end of the horn and the range is dependent on the horn type
and any extensions.
2.2.1.13. Far Range
Allows the material level to drop below Low Calibration Point without
generating a Loss of Echo (LOE) state. Unit is defined in Sensor units. See
2.2.1.5. Operation for an illustration.
Use this feature if the measured surface can drop below the Low Cal. Point
in normal operation.
2.2.1.25. Sensor Offset
A constant offset that can be added to Sensor value
1)
to compensate if the
sensor has been changed. Units are defined in Sensor Units.
Options
ON, OFF. Default: On
