A phase locked loop device includes a phase detector that measures a difference in phase between a reference clock signal and an output clock signal of the phase locked loop. According to the invention, one or more characteristic parameters are measured after excitation of the system, where these parameters are taken into consideration in the evaluation of the measurement. Rendering parameters are generated according to the obtained image quality aim and the one or more obtained image properties. The adjustable appendage has a bias element that exerts a force on the adjustable appendage in a direction towards the fixed appendage. an altered pH optimum, improved thermostability, increased specific activity, an altered cleavage pattern or an increased ability to reduce retrogradation of starch or staling of bread.
