Physical Base of Experiments

By the experiments we used the designed device PoPoLab. We plugged in all necessary cables, set the port, which is used by the system to communicate with the computer, and we set the directory, which stores the measured data for the further examination and analysis. After the program started we had to wait for a moment when the liquid in the measuring cylinder was steady and after that we started the experiment. We are able to stop the experiment at any time and save the measured data. Otherwise it will stop automatically after eight minutes. This is enough time for any of the frequently used liquids to warm up. We can load and simulate previously measured data from saved file and show its graph at any time.
