Temperature Uniformity Calibration

Temperature uniformity calibration measures the temperature difference between

a test location and a reference location. Perform this procedure for each location

within the fluid where devices will be placed for measurement. Also perform the

procedure at each setpoint at which devices will be measured.
The temperature uniformity calibration requires two reference PRTs of the type

and specifications stated in Table 12. The test also requires a modified probe

access cover that has holes at the locations of interest.
To calibrate the temperature uniformity:
1. Insert the first reference PRT into the tank at the reference location, placing

the tip of the PRT 15 mm above the bottom of the tank.

2.  Insert the second reference PRT into the tank at the test location.
3.  Set the setpoint to the required temperature.
4.  Wait for the control indicator to show stable.
5.  Wait at least another 15 minutes for complete settling.
6.  Measure the average temperature of both PRTs with at least 20 samples

over 5 minutes.

7. Calculate the temperature uniformity error as the difference between the

average temperatures of the two PRTs.
