Abstract
An error compensation system and method may include applying a mechanical load to a reference sample to obtain a load measurement signal from the load sensor and a displacement measurement signal from the displacement sensor, calculating a transfer function to create a load filter and a displacement filter to be applied to the load measurement signal and the displacement measurement signal, respectively, applying the load filter to the load measurement signal to calculate a load compensation value, and applying the displacement filter to the displacement measurement signal to calculate a displacement compensation value, and determining the compensated value by comparing the load compensation value with the displacement compensation value, wherein the compensated value is determined prior to testing a specimen so that the compensated value is used to automatically correct a measured deflection of the specimen to arrive at an actual specimen deflection.
