Proof 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 proof mass that deforms a spring in an accelerometer is sometimes called the seismic mass.[2]
A mass used to calibrate a weighing scale is sometimes called a calibration mass or calibration weight.
