Abstract
The experience gained during four years of operation of the CMD-2 drif t chamber is reported. Offline calibration of the DC parameters using a sample of Bhabha scattering events is described. Fine corrections to the Lorentz angle allow one to improve the momentum resolution. The s ystematic error in the determination of the polar angle was substantia lly decreased when information from the Z-chamber cathode was used for calibration.
