Parameters
2.3.4. Loss of Echo (LOE) Timer
Sets the time to elapse since the last valid reading, before a fault code is
reported.
2.3.5. Calibration
2.3.5.1. Low Calibration Point
Distance from sensor reference point
1)
to Low Calibration Point
(corresponding to Low Level Point). Unit is defined in Unit (2.3.1.)
2.3.5.2. High Calibration Point
Distance from sensor reference point
1)
to High Calibration Point
(corresponding to High Level Point). Unit is defined in Unit (2.3.1.).
2.3.5.3. Sensor Offset
A constant offset (negative or positive) that can be added to the sensor
value
2)
to compensate if the sensor reference point has shifted. (For
example, this could result from adding a thicker gasket or reducing the
standoff/nozzle height.) The units are defined in Unit (2.3.1.).
