	Two quadrupoles and one screen are used for beam transverse emittance measurements at HZDR ELBE. In this paper, the emittance calculated with two different methods, one with thin-lens approximation and the other one without this approximation, are compared and analized. To analyze the measurement error, quadrupole calibration is need. Two aspects about quadrupole analysis are made. The first one is quadrupole¿s effective length and strength and the second one is quadrupole¿s converged or diverged ability in reality.

To analyze the measurement error, quadrupole calibration is need. Two aspects about quadrupole analysis are made.
