Popis:	We describe two methods of fast condition diagnostics of the reflecting surface of the RATAN-600 radio telescope. The first one is based on a radio holography, and the second one relies on measurements of the random scattered background in the observations of the extended radio sources. Both methods were used in the antenna measurements, which proved the reflecting surface of the of the radio telescope main mirror to be in acceptable condition even after 20 years since the last resurfacing.
