  The Metrology Light Source (MLS), the new electron storage ring of the Physikalisch-Technische Bundesanstalt (PTB) located next to BESSY II in Berlin - Adlershof is dedicated to metrology and technology development in the UV and EUV spectral range as well as in the IR and THz region. The MLS can be operated at various electron beam energies up to approx. 600 MeV and at electron beam currents varying from 1 pA (one stored electron) up to 200 mA and is optimized for the generation of coherent synchrotron radiation. Of special interest for PTB is the operation of the MLS as a primary radiation source standard from the visible up to the X-ray region. Therefore the MLS is equipped with all the instrumentation necessary to measure the storage ring parameters needed for the calculation of the spectral photon flux according to the Schwinger theory with low uncertainty. The instrumentation and measurement results for the determination of the storage ring parameters are presented.
