Humidity and Temperature Data Logger Calibration

Data Loggers in the Chamber.

Figure 3.1

Calibration article (DUT) Humidity and Temperature Data Logger positioned in the chamber using the shelf accessory. Locate the 2500 chamber temperature sensor with the RH/Temp loggers. Close the 2500 chamber door.



From the Profile Menu Select Open Profile...

Figure 3.2

Open ControLog® software; under the Profile menu select Open Profile.



Enter the Profile Test Points.

Figure 3.3

The profile test points will be 40% & 60 %RH, the test temperature has been entered as 23.0 °C, a flow rate of 20 SLPM, you should always run the 2500 at the maximum flow rate of 20 SLPM for best uniformity of the test chamber. The ramp time entered is 0; we want the 2500 to reach the set point as fast as possible. The soak time for each test point will be 8 hours. This time can be reduced based on the response time of the DUT. We have selected NO for the assured soak conditions; the 2500 will stabilize as close as possible to the test point as selected.



From the Run Menu Select Auto Profile.

Figure 3.4

Select Auto Profile under the Run menu from the tool bar, the Auto Profile insert will be displayed with the first set point highlighted, click OK the 2500 will start at the first test point of 40.0 %RH at a test temperature of 23 °C.



Click OK to Start the First Test Point.

Figure 3.5

Click OK the 2500 will start at the first test point of 40 %RH at a test temperature of 23 °C.



The Set Point is Set at 40 %RH and Test Temp at 23 C.

Figure 3.6

Note the set point of 40.0 %RH at a test temperature of 23 °C.



The Run Sceen Displays the Set Points.

Figure 3.7

The 2500 run screen will display the set points as programmed from ControLog® Auto Profile.



The ControLog Graph Shows 40% and 60 %RH.

Figure 3.8

After 16 hours of Auto profile calibration the ControLog® graph displays the 2 point profile from 40 %RH to 60 %RH. The ControLog® graph confirms the stability and time duration of the Auto profile. The file should be saved with appropriate serial number or file name for the RH/Temp loggers.
