2.3.1.4 Setting Up an AMH Mass Set
PG9000 AMH masses are shipped in reusable, molded shipping and storage cases.
One of the cases contains the binary masses, binary mass carrier, mass bell and
mass lifting shaft. The other cases contain the 10 kg main masses. Each mass is
packed in a plastic bag and then placed in a protective shipping insert.

Caution
The stability over time of PG9000 pressure measurements is a
function of the stability of the masses loaded on the piston.
Precautions should be taken in handling the masses to minimize
influences that may change their mass. This includes always
wearing protective gloves when handling the masses to avoid
contaminating them with body oils and perspiration. Protective
gloves are provided in the accessory kits of PG9000 Platforms.
Shown is the MS-AMH-100 mass set for the AMH-100-VAC mass handler. Smaller mass sets
may be used with AMH-100-VAC which include fewer main mass discs.
