D1 and D2 density calibration using ProLink II
9.3.2
Perform a D1 and D2 density calibration using
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.
• The calibrations must be performed without interruption, in the order shown. Make sure that you
are prepared to complete the process without interruption.
• Before performing the calibration, record your current calibration parameters. If the calibration
fails, restore the known values.
Restriction
For T-Series sensors, the D1 calibration must be performed on air and the D2 calibration must be
performed on water.
