Abstract: A method is described for calibrating a characteristic diagram of a working machine. The characteristic diagram includes a brake pedal characteristic of a brake system and at least one clutch characteristic of a drive input clutch which, in the calibrated condition, have a nominal relationship to one another. The method having the steps of: determining a wheel-side drive output torque; determining an actual brake pedal characteristic with reference to the drive output torque; determining an actual relationship that differs from the nominal relationship by comparing the actual brake pedal characteristic with a nominal brake pedal characteristic; and calibrating the brake pedal characteristic or the clutch characteristic in such manner that the actual relationship corresponds to the nominal relationship. In addition a working machine with a control unit for carrying out the method is described.

Abstract: In a clarification method for a beverage liquid, in particular for producing beer, the beverage liquid, after it passes through a fermentation stage, is subjected to a clarification which serves for removing active haze components from the beverage liquid, and fed to a maturation vessel in which the beverage liquid is stored for a maturation time. In a further method step, the beverage liquid is charged with at least one pectin-containing clarification agent for increasing a filtration performance. In this case it is provided that the pectin-containing clarification agent is introduced into the beverage liquid on the path from the fermentation stage to the maturation vessel and the pectin present therein, before the feed to the maturation vessel, is at least for the most part removed again from the beverage liquid.
