Abstract We measure instrumental asymmetries of kaons and pions using D0Kπ+ and DKS0π decays. We use the data collected by Belle II at the Υ(4S) energy during 2019, 2020 and the first half of 2021 which correspond to 189\,fb1 of integrated luminosity. We study the dependence of the instrumental asymmetries on the momentum and polar angle of the particle and on the number of drift-chamber hits of its track.
