Changing certain parameters such as all sensor characteristics, for example, influences numerous
functions of the entire measuring system, particularly measuring accuracy. There is no need to
change these parameters under normal circumstances and consequently, they are protected by a
special code known only to the Hauser service organization. Please contact
