Previous studies of the D[O] calorimeter with electron and hadron beams above 10 GeV/c have shown excellent linearity of response and e/[pi] ratio close to one. Here we report on our measurements of the response of the DO central calorimeter modules down to 2 GeV/c. The measured low energy response for electrons and pions are fragmentation from the PYTHIA Monte Carlo to obtain the corrections for jet energy
