We present results of extensive calibration program performed with ART-XC telescope during the first months of SRG operation. Performance of the ART-XC detectors was calibrated with use of onboard radioactive source while effective area and
point spread function were verified during observations of bright X-ray sources. The derived detector energy resolution of 9% at 14 keV is in good agreement with ground-based measurements.
