Geometry Mass
Geometry mass (weight) is an important parameter that enables the RSA-G2 to account for the effects of
test geometry inertia at higher frequencies. The mass of the geometries are entered when configuring a
geometry in TRIOS software. Some of the geometries’ mass are listed in Table
. For special or unknown
geometries, obtain the mass through direct weighing with the RSA-G2 transducer, or perform the Upper
Fixture Mass Calibration in TRIOS software. Refer to TRIOS Help for additional information.
