The Dortmund Electron Accelerator (DELTA, Germany) operated as 1.5 GeV synchrotron radiation source requires a superconducting wiggler as an insertion device for three x-ray beamlines with photon energies up to more than 30 keV. The article describes all the stages of magnetic measurement procedure. During preliminary tests in a submerged cryostat the magnetic system was trained and the magnetic field integrals were evaluated. Based on the measurement results, the final correction of the geometry of the wiggler was made by adjustment of the distances between the inner and the end poles. The whole cycle of magnetic measurements was carried out in the own cryostat and the table of working currents was prepared.
