In a measurement method, a plurality of magnetic field sensors (MS0-MS15) that are arranged along a circular periphery (CIR) and are each configured to emit a sensor signal (H0-H15) as a function of a magnetic field intensity is provided. A diametrically magnetized magnetic source (MAG) seated rotatably on the circular periphery (CIR) about an axis of rotation (RA) is further provided. A first set of sensor signals from the magnetic field sensors (MS0-MS15) is received and a first orientation (AL1) of an axis (AX) defined by a reference value transition (RFD) is determined as a function the first set. After a rotation of the magnetic source (MAG) about the axis of rotation (RA), a second set of sensor signals is received and a second orientation (AL2) of the axis (AX) is determined as a function of the second set of sensor signals. A position (X0, Y0) of the axis of rotation (RA) is acquired as a function of the first and the second orientation (AL1, AL2).
