Calibration Report
The Calibration Report details which parameters were set during calibration.
1. Select View > Calibration Report.
2. Select the Calibration Report to be viewed. The file has the extension
*.800 and is located in the default directory C:/Program
Files/Rosemount User Interface for Windows/Data directory unless
the directory location was changed when the Calibration Report was
created.
3. Click Open.
Calibration Value
Select Utilities > Calibration Value to view the calibration values for a specific
analog input point.
NOTE
Remove/restore the device from/to working pressure during calibration.
Failure to follow recommendations may cause sensor damage.
Zero Shift
To check or adjust for Zero Shift, leave the sensor by-pass valve open (to
simulate a no-flow condition), with either line pressure or a normal operating
SP from the calibrator applied to the sensor. This applies the same pressure
to both sides of the DP diaphragm to give a zero DP reading.
Perform the following steps:
1. Connect the Rosemount User Interface Software to the 3095FC and
run the calibration procedure.
2. Select Meter > Calibration > Freeze.
3. Under the Diff Press input, click Zero Shift to open the Set Zero Shift
window.
4. Verify Reading to determine if a Zero Shift correction is required.
5. If the reading is not zero, click Set Zero Shift to adjust the Zero and
click Done. If the reading is zero, click Done.
6. Click Done to close the calibration window and cancel the freeze
values to begin using live readings for the flow calculations.
