We report on a new technique of a Multi-Cathode Counter (MCC) developed tosearch for hidden photon (HP) cold dark matter (CDM) with a mass from 5 to 500eV. The method suggested in the assumption that hidden photons of the massgreater than a work function of the metal, the cathode of the counter isfabricated induce emission of single electrons from a cathode. Threeconfigurations of the same counter are used to measure the count rates R1, R2and R3 of the single electron events during several weeks. As a measure of theeffect from HP the difference R1-(R2-D3/D2xR3) has been used. Some preliminaryresults have been obtained on a first try to search for HP with a mass from 5to 500 eV. The upper limit for mixing parameter X has been set on the level of3.3x10-10 for hidden photon mass from 9 to 100 eV. In our plans is to refinethe procedure of data treatment and to continue the measurements to collectmore data.
