Test description
The sample is placed below the measuring head. On pushing the start button, the 10 kg weight lowers onto the sample, which helps to hold it tight to the glass plate.

The built-in vacuum pump evacuates the selected tank to a vacuum of -50.7 kPa. Depending on the surface roughness of the sample, atmospheric air is drawn in between the glass plate and the sample.

The time taken for the vacuum to reach -48.0 kPa (res. 29.3 kPa) is displayed in Bekk seconds.
Ten seconds after the test has started a preview is displayed to give an advanced estimate of the result.
