Zusammenfassung:In a method for measuring the injection quantity of injection systems, in particular for motor vehicles and in particular in production testing, an injection system injects a testing fluid into a measuring chamber. A detection device detects a movement of a piston, which at least partially defines the measuring chamber. This detection device generates a corresponding measurement signal. In order to increase the precision of the calculation of the injected testing fluid mass, the invention proposes that the pressure of the testing fluid in the measuring chamber be detected and that the measurement signal be processed taking into account the detected pressure.
