Proof mass
From HandWiki
Short description: SAMPLE MASS
A proof mass or test mass is a known quantity of mass used in a measuring instrument as a reference for the measurement of an unknown quantity.[1]
A mass used to calibrate a weighing scale is sometimes called a calibration mass or calibration weight.
A proof mass that deforms a spring in an accelerometer is sometimes called the seismic mass.[2] In a convective accelerometer, a fluid proof mass may be employed.[3]
