Abstract
A method determines measurement data of samples by using a rotation rheometer and a linear DM(T)A analysis unit. The rotation rheometer has units for measuring and/or adjusting the normal force exerted by or on the measurement shaft and/or the speed, deflection angle and/or torque of the measurement shaft. The linear DM(T)A analysis unit has units for measuring the tensile and/or pressure force and/or the position and/or the feed movement of its adjustment rod. The sample to be examined is arranged between opposite measurement parts. Accordingly, the rotational forces or torques transmitted via the sample from the measurement shaft to the adjusting rod, when obtaining measurement data with the linear DM(T)A analysis unit, and, when obtaining measurement data by the rotation rheometer, for the tensile or pressure forces or linear adjustment forces transmitted via the sample from the adjustment rod to the measurement shaft are compensated for.
