"placed directly on your ami · membrane sealed * you Also consists of your positive crystal tiles, which are seldom facing each other, "wipe them" int metallic and reads a current arrester attached plate ;. Dl · · «plate serves as a positive pole, while that directly on the negative Housing that rests on the cell rarely forms the negative connection.

The voltage emitted by the cell is fed to several measuring devices via tubes * or transistor amplifiers. One of these measuring devices is a pulse counter which, with suitable sieving, allows the engine speed to be read directly. With a voltmeter connected to the cell, the injection pressure is determined. A stroboscopic lamp is attached to the cell, χ.B. an electron "blitx lamp connected, oil" - on which the bits of a coffee-equipped flywheel are aligned. Herewith XXSt calibrate the injection start depending on the position of the swing lever and, therefore, depending on the position of the piston, the best ions.
