9 Measurement support
Topics covered in this chapter:
• Perform the Known Density Verification procedure
• Adjust density measurement with Density Offset or Density Meter Factor
• Perform density offset calibration
• Adjust temperature measurement with Temperature Offset
• Adjust concentration measurement with Trim Offset
• Adjust concentration measurement with Trim Offset and Trim Slope
• Set up user‐defined calculations
9.1 Perform the Known Density Verification
procedure
The Known Density Verification procedure is used to verify that the meter's current
operation matches the factory baseline. If the meter passes the test, the meter does not
have any physical problems such as denting, bending, twisting, erosion, or corrosion.
• Perform the Known Density Verification procedure using the display (Section 9.1.1)
• Perform the Known Density Verification procedure using ProLink III (Section 9.1.2)
• Perform the Known Density Verification procedure using the Field Communicator
(Section 9.1.3)
9.1.1 Perform the Known Density Verification procedure using
the display
The Known Density Verification procedure is used to verify that the meter's current
operation matches the factory baseline. If the meter passes the test, the meter does not
have any physical problems such as denting, bending, twisting, erosion, or corrosion.
Prerequisites
Power down the meter, remove the meter from the process, and place it in a protected
stable environment.
Ensure that the sensor tubes are clean and dry.
Minimize variation in ambient temperature.
Eliminate or minimize vibration.
Power up the meter.
