Test description:
Up to 16 samples (acc. to standard 4 samples), prepared with the sample punch, are laid one on top of another and placed in the sample holder. On the touch screen, the number pf samples inserted is selected, these are allocated to a test series (MD/CD) and the start button is pressed.
