a method and a device determine tribological measured values of samples with a rheometer . wherein the measuring parts of the rheometer are replaced by samples and the surfaces of the samples are moved into frictional contact relative to each other . accordingly , it is provided that all parts of the rheometer holding the samples in frictional connection and frictional contact or forming the rheometer power circuit , including the spring unit pressing the samples against each other , are regarded as an oscillatory circuit . the oscillation properties of the spring unit are regarded as relevant to the oscillation properties of the oscillatory circuit , and that the oscillation properties of the spring unit are adjusted taking into consideration the resonance oscillations or effects produced by changing , different measurement conditions expected with the respective measurement .
