Before dropping the caster, set up the drop surface on top of your work bench. Make sure that the area is clear. Warn others in the room that you are about to drop the caster. This test will be loud.
You may drop the caster multiple times in each configuration. After you click "Continue", the computer will prompt you with the next drop. Follow the pictures shown on this screen when dropping the caster.
Keep your hands and other body parts away from the caster while it is dropping.
If at any time you see scratches, burrs or dents in the caster, stop the test immediately by clicking cancel. The computer will automatically fail the test if the caster looses power or drops packets.
