When the diaphragm capsule is dry an cold, the diaphragm must be in contact with the top
part of the wall (as shown in Fig. 10 and Fig. 12).
If the diaphragm is away from the top surface, and/or in contact with the bottom part of the
wall (as shown in Fig. 11 and Fig. 13), the capsule is defective and should be replaced.
