Abstract
A method is for calibrating a multiturn sensor for determining the position of a spindle of a clutch actuator, in which the multiturn sensor () is operatively connected to a magnetic field of a permanent magnet () in that the multiturn sensor () is combined with an actuator transmission () which comprises a spindle () bearing the permanent magnet (). In a calibration method which can be carried out particularly quickly and cost-effectively, during the assembly of the multiturn sensor (), arranged on a carrier element (), with the actuator transmission () bearing the spindle (), the multiturn sensor () is operated outside its specified rotational range (0, n), wherein a position, set by actuating the actuator transmission (), of the spindle () bearing the permanent magnet () provided for an operating case of the clutch actuator (), is assigned to a specified end position of the rotational range (0, n) of the multiturn sensor (), as a result of which a magnetic field of the permanent magnet () is aligned with the multiturn sensor ().
