Hydrostatic buoyancy correction and calibration points interpolation using tare weights

Abstract Some weighing results requires high accuracy. Users frequently perform manual procedures to make these corrections. Two of these corrections are the hydrostatic buoyancy force and the balance calibration certificate corrections, the last one can be influenced by the tare weights use, and the tare function, in the weighing procedure. To provide an easy way to consider both simultaneously a spreadsheet was developed to identify and interpolate the right values obtained in the calibration certificate data and to use these data to correct the buoyancy force. In a first step, it will be distributed to the Inmetro´s laboratories.
