The determination of the mechanical properties of polymer-surfaces is a widespread task in the AFM community. The most important step in measuring is the thorough calibration of the measurement setup. Here, we address that problem for the case of Digital Pulsed Force Mode measurements. We show that following our suggestions, one can get reliable and consistent quantitative data on the mechanical properties of polymers such as PMMA or SBR rubber. The influence of the individual cantilevers and their properties, as well as the variations due to the settings of the AFM are widely eliminated.
