A knife connector includes a base, a cover, a clamping device and a connecting stub. Each tube includes a plurality of indentations. The normal output generation is continued until the charge level SOC reaches a generation end value SOCend larger than the generation start value SOCsta. The value of each update increment is nominally equal to the quotient, with the remainder being distributed relatively evenly by adding one to selected updates. A snap ring is arranged in the groove of the fuel injector and is designed to fixedly couple the second plate element to the fuel injector. The method envisages reducing the electrical stress to which the reference memory cell is subjected during reading, by generating and holding a sample of the reference voltage, then deselecting the reference memory cell, and then continuing reading using the sample of the reference voltage.
