5. If you are using the offset to adjust temperature measurement, set Temperature Offset
to the calculated value.
• Using the display: Not available
• Using ProLink III: Device Tools > Configuration > Process Measurement > Line Temperature
> Temperature Offset
• Using the Field Communicator: Not available
The default value is 0. The range is unlimited.
6. If you are using the slope to adjust temperature measurement, set Temperature Slope
to the calculated value.
• Using the display: Not available
• Using ProLink III: Device Tools > Configuration > Process Measurement > Line Temperature
> Temperature Slope
• Using the Field Communicator: Not available
The default value is 1.0. The recommended range is 0.8 to 1.2. If your calculated
slope is outside this range, contact Micro Motion customer service.
9.7 Perform temperature calibration
Temperature calibration establishes the relationship between the temperature of the
calibration fluids and the signal produced by the sensor.
• Perform temperature calibration using the display (Section 9.7.1)
• Perform temperature calibration using ProLink III (Section 9.7.2)
• Perform temperature calibration using the Field Communicator (Section 9.7.3)
9.7.1 Perform temperature calibration using the display
Temperature calibration establishes the relationship between the temperature of the
calibration fluids and the signal produced by the sensor.
Prerequisites
The temperature calibration is a two-part procedure: temperature offset calibration and
temperature slope calibration. The two parts must be performed without interruption, in
the order shown. Ensure that you are prepared to complete the process without
interruption. You will need a low-temperature calibration fluid and a high-temperature
calibration fluid. You will not see the effect of the calibration until both the temperature
offset calibration and the temperature slope calibration are complete.
Important
Consult Micro Motion before performing a temperature calibration. Under normal circumstances,
the temperature circuit is stable and should not need an adjustment.
