Abstract

PURPOSE:To remove influence by a difference of gravity, to make calibration of gravity unnecessary, and to exactly execute measurement of mass, by deleting a factor of gravity acceleration from a load measuring output, in an operation part. CONSTITUTION:A load detecting part 1 weighs a sample S on a scale 2, V/F converts 3 voltage corresponding to weight W of the sample S, and supplies it to an operation part 4. Also, a gravity acceleration measuring part 5 is operated, a period T of a pendulum 51 in a place where a balance is installed, and is supplied to the operation part 4. In the operation part 4, the gravity acceleration in the place where the balance is installed is deleted, and mass M is derived. Accordingly, an error due to a difference of gravity is not generated at all, and weighing is executed exactly.
