Method for acquiring adjustment data of a centrifugal spreader which has two centrifugal discs which are arranged spaced apart from one another, are driven so as to rotate in opposite directions, are fitted with throwing blades and to which manure particles which can be discharged in a meterable fashion via adjustable metering elements are fed and which has means for influencing the distribution accuracy of the manure particles, and in which the supplied manure particles are distributed in the form of a fan of the manure by its throwing blades, wherein in the method the manure particles are thrown by a testing device, which has a centrifugal disc with throwing blades and to which a metering element is assigned, in the direction of a relatively long measuring device which has balancing units, via the centrifugal disc of the testing device, with the result that the measuring device catches the manure particles landing on it, characterized by the following method steps: - step 1 arrangement of at least one centrifugal disc with an assigned metering element at one end of the relatively long measuring device in a spatial position which is invariable with respect to the measuring device at least when the manure particles are being thrown; - step 2 arrangement of at least two sensors which operate in a contactless fashion, at a distance from the outer ends of the throwing blades, which scatter the manure particles and are driven in rotation, of the centrifugal disc of the testing device in order to record the measurement data of the manure particles which are scattered by the throwing blades; - step 3 orientation of the metering element of the testing device with respect to the centrifugal disc of the testing device in order to adjust the feed face of the manure particles on this centrifugal disc in such a way that the manure particles are scattered in the direction of the measuring device; - step 4 application of manure particles to the centrifugal disc of the testing device in a first scattering process, sensing of the manure particles by the sensors and transmission of the measurement data, acquired by the sensors, to a data processing device; - step 5 acquiring the maximum quantity of manure particles in the fan of manure and its position on the basis of the measurement data from the first scattering process by means of the data processing device and adjusting the feed face of the manure particles onto the centrifugal disc in accordance with the maximum quantity of the manure particles and its position for a second scattering process with an intended maximum quantity of manure particles in the fan of manure, at least approximately perpendicularly above the relatively long measuring device; - step 6 carrying out a second scattering process with the setting acquired according to step 5 and determining measurement data by means of the sensors and the balancing units of the relatively long measuring device and their transmission to the data processing device, from which measurement data the data processing device acquires adjustment data for the centrifugal spreader on the basis of the transmitted measurement data relating to the second scattering process. - step 1 arrangement of at least one centrifugal disc with an assigned metering element at one end of the relatively long measuring device in a spatial position which is invariable with respect to the measuring device at least when the manure particles are being thrown;
