The motion involved in the operation of an oscillating rheometer was analyzed, and revealed that the instrument measured a complex mixture of an instrument-dependent parameter, the spring constant, and two material-dependent parameters- the dynamic viscosity and the shear storage modulus. The significance of the working and setting time parameters measured by the rheometer are discussed.
