Live analysis
Do live analysis: Enables real-time result analysis. Results are shown in the Live analysis-screen in the
lower part of the tab.
Analysis mode: Drop-down menu enabling to choose preferred analysis (i.e. fitting) mode.
Use Autobaseline: Enables to use automatic baseline in the live analysis.
Flip Y: Needs to be chosen if a hooked needle is used. The analysis software will then flip the image
vertically to be able to perform the analysis. Image will not be flipped on the screen.
Saving
Image recording settings: Summary of chosen image recording settings. By clicking this buttom, different
camera parameter combinations can be saved.
Mode: Basic mode is chosen as a default mode, which enables to image one phase frame per second
(FPS) measurements. In case two phase imaging (i final) is preferred, choose the Advanced
mode. Live images only mode records only live images, in which the frame rate cannot be adjusted.
Total duration [s]: Total recording time including both initial and final recoding times.
Initial pause [s]: Pause before starting recording. Typically used in contact angle experiments, when the
most stable contact angle value is recorded after certain time period.
Initial FPS: In case Advanced Image recording mode is used, the initial frame rate can be set here.
Initial duration [s]: In case Advanced Image recording mode is used, the initial recording time is set here.
Software calculates automatically the initial duration, after the total and final duration has been set on the
screen.
Final FPS: In case of Advanced mode is used, the frame rate of the final phase is set here. In Basic
mode, the frame rate is set here as well.
Final duration [s]: In case of Advanced mode is used, the final frame rate can be set here.
Start saving when: Choose from this drop down menu the preferred point of time/ action, when the
recording starts.
Stop from trigger: Enable to stop the recording by using the trigger. A trigger can be used to start the
image recording after a specific event. In this case it is when a pixel changes from either white to black
or black to white.
Materials
Solid: You can either choose a solid from the readily created solid database, or add a new sample of
your choice. This can be done the same way as the addition of the probe and the vessel. This time the
―Editor‖ window will ask you a name for your sample, surface tension or surface energy of your sample
(

), dispersive component of surface tension (

d
), acid component of surface tension (

+
), base
component of surface tension (

-
)
as well as the density (ρ).
Light phase: Can be chosen from the readily created database or be added as above. Additional
parameters are the viscosity (η), temperature, and molecular weight of the phase.
Heavy phase: Can be chosen from the readily created database or be added as above.
