Perform Temperature Calibration Using A Fieldbus Host - Emerson Micro Motion 2700 Configuration And Use Manual

Important
Consult customer support before performing a temperature calibration. Under normal
circumstances, the temperature circuit is stable and should not need an adjustment.

When the calibration is complete, the updated temperature offset and temperature slope
values are stored in transmitter memory. To read them:

Fill the sensor with the low-temperature fluid.
Wait until the sensor achieves thermal equilibrium.
Enter the temperature of the low-temperature fluid: Calibration TB > TEMP_VALUE
(OD Index 44).
Write 1 to Calibration TB > TEMP_LOW_CAL (OD Index 42) to start the temperature
offset calibration.
Monitor the calibration using Calibration TB > SNS_ZeroInProgress (OD Index 55).
• 0=No calibration in progress

Fill the sensor with the high-temperature fluid.
Wait until the sensor achieves thermal equilibrium.
Enter the temperature of the high-temperature fluid: Calibration TB > TEMP_VALUE
