The first protons were accelerated at the ESS site during the commissioning of the ion source and low energy beam transport (LEBT), that started in September 2018 and ran until July 2019. Misalignments of the elements in the LEBT can have a strong impact on the final current transmission of the low energy part. In this paper, we present a way to isolate and measure tilts of the elements and the initial centroid divergence of the source. We also present initial test measurements for the ESS LEBT and discuss how to extend the method to other facilities.
