Explanation
Searches for the surface: the liquid
is moved upwards until the probe
"jump" is registered. The surface
position is stored.
Immerses the probe to the given
immersion depth.
Returns to the found surface
height.
Records measured values until the
required number of values has
been obtained.
The measurement is complete.
The data found are used to display
the mean value of the interfacial
tension, the standard deviation
and the temperature.
