In the KASCADE-Grande experiment at the Forschungszentrum Karlsruhe, a hadron sampling calorimeter equipped with liquid ionization chambers is used. The chambers are filled with the warm liquids tetramethylpentane (TMP) and tetramethylsilane (TMS). In order to obtain calibration data, a similar calorimeter was built and tested at CERN in 2003. It consists of 15 layers (1× 1 m²) of liquid ionisation chambers filled with TMP at room temperature. Between these layers there are 13 iron absorbers of 10 cm thickness each. In addition one layer of lead absorber (5 cm thick) is installed between the first and the second layer of the ionisation chambers. The energy deposited was measured for three types of particles (hadrons, muons and electrons) with energies between 15 GeV and 350 GeV. The data taken are compared to the results of Monte Carlo simulations employing the FLUKA code. Results of the analysis will be presented.
