Calibrating the Transmitter
C.1 Overview
This section describes transmitter calibration procedures. Using these procedures, you will be able to:
• Calibrate for density
• Calibrate for temperature
Note: All ProLink II procedures provided in this section assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 3 for more
information.
Note: All HART Communicator key sequences in this section assume that you are starting from the
“Online” menu. See Chapter 4 for more information.
C.2 About calibration
The flowmeter measures process variables based on fixed points of reference. Calibration adjusts
those points of reference.
The transmitter is factory calibrated and does not normally need to be calibrated in the field. Calibrate
the transmitter only if you must do so to meet regulatory requirements.
Note: Micro Motion recommends using meter factors, rather than calibration, to prove the meter
against a regulatory standard or to correct measurement error. Contact Micro Motion before
calibrating your flowmeter. For information on meter factors, see Section 8.13.
C.3 Density calibration
Density calibration includes the following calibration points:
• All sensors:
- D1 calibration (low-density)
- D2 calibration (high-density)
• T-Series sensors only:
- D3 calibration (optional)
- D4 calibration (optional)
For T-Series sensors, the optional D3 and D4 calibrations could improve the accuracy of the density
measurement. If you choose to perform the D3 and D4 calibration:
• Do not perform the D1 or D2 calibration.
• Perform D3 calibration if you have one calibrated fluid.
• Perform both D3 and D4 calibrations if you have two calibrated fluids (other than air and
water).
