The microwave cavity experiment WISPDMX is the first direct WISP (Weakly interactive slim particles) dark matter search experiment probing the particle masses in the 08-20 eV range The first stage of WISPDMX measurements has been completed at nominal resonant frequencies of the cavity The upgrading of the data acquisition and analysing has been done to increase the sensitivity of the experiment We report preliminary result from the cavity tuning at second stage of WISPDMX
