3. To perform the temperature slope calibration:

a. Pump a process fluid through the sensor at the highest

temperature measured during the application.

b. Wait approximately five minutes for the flow tube temperature to

stabilize.

c. Use a highly accurate thermometer, temperature sensor, or

another device to measure the temperature of the process fluid.

d. Open the Calibrate menu, then choose Temperature. At the

cascading menu, choose Slope Calibration to open the

Temperature Slope Calibration dialog box, shown in

Figure 14-12

e. Enter the temperature that was measured in step 3c into the

Enter Temp text box, then choose Do Cal. The transmitter

calculates the slope and offset of the linear representation of

temperature and enters these factors into the microprocessor.
