4. Place shielding plate on object table.
5. Mount compression plate and perform compression.
6. Perform an exposure.
7. Check that the radiation signal lights up very shortly and exposure is interrupted,
tube load is below 5 mAs.
8. Check that a warning is shown.
9. Note result in Test form Test 1.
10. Deactivate examination, remove shielding plate.
