2.3.5.3.
A constant offset (negative or positive) that can be added to sensor value
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.).
Values
Related parameters
2.3.5.4.
The level when the material is at Low Calibration Point. The unit is defined
in Level Unit (2.3.2.).
Values
2.3.5.5.
The level when the material is at High Calibration Point. The unit is defined
in Level Unit (2.3.2.).
Values
2.3.5.6.
A constant offset that can be added to Level. The unit is defined in Level
Unit (2.3.2.).
Values
2.3.6. Rate
Note: Default settings in the parameter tables are indicated with an asterisk
(*) unless explicitly stated.
2.3.6.1.
Notes:
• Changing Response Rate resets Fill Rate/Min (2.3.6.2.), Empty rate/
• Selecting SLOW changes setting for Average amount (2.8.3.) to 0.9.
Sets the reaction speed of the device to measurement changes.
Response Rate
(2.3.6.1.)
*
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
