Abstract: A method and a device measure tribological values of samples with a rheometer. Wherein measuring parts of the rheometer are replaced by the 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 supporting the samples in frictional connection or frictional contact and forming the rheometer power circuit, including a spring unit pressing the samples against each other, are regarded as an oscillatory circuit. Oscillation properties of the spring unit are relevant to oscillation properties of the oscillatory circuit. The oscillation properties of the spring unit are adjusted taking into consideration resonance oscillations or effects produced by changing or different measurement conditions expected with the respective measurement.
