Parameters
2.3.5.3. Sensor Offset
A constant offset (negative or positive) that can be added to sensor value
1)
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.).
2.3.5.4. Low Level Point
The level when the material is at Low Calibration Point. The unit is defined
in Level Unit (2.3.2.).
2.3.5.5. High Level Point
The level when the material is at High Calibration Point. The unit is defined
in Level Unit (2.3.2.).
2.3.5.6. Level Offset
A constant offset that can be added to Level. The unit is defined in Level
Unit (2.3.2.).
2.3.6. Rate
2.3.6.1. Response Rate
Sets the reaction speed of the device to measurement changes. .
Use a setting just faster than the maximum filling or emptying rate
(whichever is greater).
1)
The distance from sensor reference point to target (see Minimum Sensor Value 2.4.3.
on page 70 for an illustration.

Note: Default settings in the parameter tables are indicated with an asterisk
(*) unless explicitly stated.
Notes:
• Changing Response Rate resets Fill Rate/Min (2.3.6.2.), Empty rate/
Min (2.3.6.3.), and Filter Time Constant (2.5.8.1.).
• Selecting SLOW changes setting for Average amount (2.8.3.) to 0.9.
