The sample to be tested is placed in the measuring area. After pressing the start button, the clamping bell lowers and fixes the sample. Glycerine underneath the membrane is compressed and the membrane is thus pressed continuously against the sample. The sample bulges, and loses cohesion, until it eventually breaks. Then the clamping bell returns to initial position. The results are shown on the display If more than one test is carried out, the results can be compared in the statistics and outliners can be taken out of the evaluation. In the statistics view you can see min. and max. values as well as the standard deviation.
