ENHANCED METHODS FOR CALCULATING UNCERTAINTY ENVELOPE FUNCTIONS FOR FORCE RANGES

D. Röske

Abstract

In static force and torque calibrations, the quantity is applied to the given measuring instrument in discrete steps to form a measurement series that usually consists of five to ten values. The corresponding calibration results and uncertainties are then acquired through calculation. During normal use of the instrument, the values measured are often distributed within a range and do not align with the calibrated values. A fitting function is then applied to the result that allows the mechanical quantity to be calculated from the indicated deflection value. The uncertainty associated with this calculation must likewise be calculated using a function defined over the range. This article presents enhanced methods for calculating this function.
