Postrequisites
If you disabled LD Optimization before the calibration procedure, re-enable it.
9.5.3 Perform a D1 and D2 density calibration using the
Field Communicator
Prerequisites
• During density calibration, the sensor must be completely filled with the calibration
fluid, and flow through the sensor must be at the lowest rate allowed by your
application. This is usually accomplished by closing the shutoff valve downstream
from the sensor, then filling the sensor with the appropriate fluid.
• D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-
density) fluid. You may use air and water.
• If LD Optimization is enabled on your meter, disable it. To do this, choose Configure >
Manual Setup > Measurements > LD Optimization. LD Optimization is used only with large
sensors in hydrocarbon applications. In some installations, only Micro Motion
customer service has access to this parameter. If this is the case, contact
Micro Motion before continuing.
• The calibrations must be performed without interruption, in the order shown. Make
sure that you are prepared to complete the process without interruption.
