The invention provides a method for operating a controlled stress rheometer in a controlled strain mode to follow a demand strain Xd in a sample having applied thereto a variable demand force Td, inducing an actual strain X including the steps of:monitoring the actual strain X;continuously comparing the actual strain X with the demand strain Xd and calculating the difference;calculating in real time, using an appropriate algorithm, the value of Td necessary to adjust the strain from X to Xd, andadjusting Td to the calculated value so as to effect this strain adjustment. The method may be performed by a computer software algorithm installed in a digital signal processor forming part of the controller system of the rheometer.
