Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Level measurement (via local operation and FieldCare)
Endress+Hauser 127
9.6.2 Dry calibration and manual entry of the linearization table
Example:
In this example, the height and the volume should be measured at the same time.
Prerequisite:
• This is a theoretical calibration, i.e. the points for the linearization table are known.
!
Note!
• See also Operating Instructions for Deltabar S (BA00301P), Cerabar S (BA00302P), "Level
measurement" section or Deltapilot (BA00372P), "Level measurement" section.
• Due to the orientation of the device, there may be a shift in the measured value, i.e. when the
container is empty, the MEASURED VALUE parameter does not display zero. → For information

Description
Perform calibration for the 1st measured variable:
P01-PMP75xxx-19-xx-xx-xx-005
1 Perform calibration as per Section 9.6.1, Steps 1 to 12.
2 Select the "Dry" option via the CALIBRATION MODE
parameter (calibration mode for the 1st measured
variable).
3 Select a density unit via the DENSITY UNIT parameter,
here kg/dm
3
for example.
4 Enter the density of the fluid via the ADJUST DENSITY
parameter, here 1.0 for example.
5 If necessary, enter a level offset via the ZERO POSITION
parameter, here 0 m for example.
6Result:
The calibration for the 1st measured variable is carried
out.
Perform linearization (calibration for the 2nd
measured variable)
7 Change the function group.
