Abstract
In an inertial mass measurement instrument, an active force compensator compensates for inertial forces transmitted by an oscillating elastic element to a primary support of the instrument. The compensator applies equal and opposite compensating forces to the primary support along an effective line of action of the oscillating element. Application of the compensating forces result in a substantially zero net acceleration of the primary support and avoids measurement inaccuracies attributable to changes in properties of secondary support elements.
