N2 - The family of four weak quadrupoles was replaced at VEPP-2000 electron-positron collider with new one. New quads with increased bore diameter made with higher field quality and equipped with fiducial points are excited by water-cooled coils fed with new 300 A power supplies. That allowed to double integrated gradient and to implement so called "warm" operation mode (with switched-off final focus solenoids) above 500 MeV energy level. Presented in the paper "warm" modes are used for beam scrubbing and for resonance depolarization technique of Comp-ton backscattering beam energy measurement system cross-calibration.
