Commissioning
7.2 Local commissioning
Note
Dynamic decimal places
Each setting for parameter "Units" has a default number of decimal places used to show the
process value on the local display. However, if the value is too large to show on the segment
display, the decimal places will be automatically adjusted to show the process value.
Lower calibration point
Sets distance from sensor reference point to lower calibration point: usually process empty
level.
Setting
Default
Defined in parameter "Units".
Upper calibration point
Sets distance from sensor reference point to upper calibration point: usually process full level.
Setting
Default
Defined in parameter "Units".
Response rate
Sets reaction speed of device to measurement changes in target range.
Use a setting just faster than the maximum filling or emptying rate (whichever is faster).
Note
Response rate
The parameter "Response rate" can only be set through the "Quick commissioning" wizard
and any changes made to parameters "Fill rate", "Empty rate" or "Damping value" following
the completion of the wizard will supersede the response rate setting.
