SO/PHI is the Polarimetric Helioseismic Imager on board the Solar Orbiter; one of the 6 remote sensing instruments. It is a spectropolarimeter: it takes images of the Sun at very distinct wavelengths and different polarisations. From these images, the full vector magnetic field at the solar surface, as well as the LOS (Line Of Sight) velocity, can be inferred. To produce reliable magnetograms and dopplergrams the polarimetry of SO/PHI-HRT has to be calibrated. This poster describes the preliminary results that characterise its polarimetric properties. : {"references": ["Rodr\u00edguez, J.
