Surface free energy experiments
A Surface free energy experiment uses information obtained from Contact angle experiments, and the
software only process the data in a different way (see Chapter 6.3). Right click on the contact angle
results and choose the contact angle or group of the contact angles, which you prefer to use in your
surface free energy calculations. This value will then be visible in Calculated results. Right click on the
chosen contact angle value in the Calculated results sheet and choose Send to SFE, after which the
SFE analysis tab will open. Repeat this for the contact angle measurements, which you want to use in
the SFE calculations. Typically, contact angles performed with 2-5 different probe liquids are used in
surface energy calculations. After you have the chosen contact angle values for the SFE analysis tab,
click Calculate. The SFE results will appear on the lower part of the SFE analysis tab.

3.1
Software overview
The OneAttension software that runs Theta has an easy and user-friendly interface. When starting the
OneAttension program (located by default on the desktop and in the Start menu under
Programs>OneAttension) first time, you are able to choose User Manager option (Figures 3.1
—3.5) and
frame rate of the Basler camera (Figure 3.2). In the User Manager option you are able to create different
user levels in the setup window by clicking Create new user under the user settings. In addition to
Administrator, who is able to manage all the users (i.e. create and remove users), Programmer and
Operator user levels can be created. The Programmer is able to create recipes, but cannot manage the
other users. The Operator is able to run ready-made recipes. The User Manager option allows to set
preferred level of privacy: Recipes and saved results can be chosen to be private only for the user.
