A method and an apparatus for setting and/or testing valves, in particular injection valves of an internal combustion engine, are described. A defined activation signal is applied to a valve in order to determine a signal characterizing the flow rate of fuel. A gaseous medium is applied to the valve. A first variable which characterizes the flow rate of the gaseous medium, and/or a second variable, are detected.

[ What is claimed is:] [1.]1. A method for calibrating a valve, comprising the steps of:providing a predetermined activation signal to the valve;providing a gaseous medium to the valve;detecting at least one of a first variable and a second variable when the gaseous medium is provided to the valve,

[ What is claimed is:] [1.]1. A method for calibrating a valve, comprising the steps of:providing a predetermined activation signal to the valve;providing a gaseous medium to the valve;detecting at least one of a first variable and a second variable when the gaseous medium is provided to the valve, wherein the first variable is indicative of a flow rate of the gaseous medium, and wherein the second variable is indicative of a value of a current controlling at least one of opening and closing the valve;determining a particular signal from the at least one of the first variable and the second variable, wherein the particular signal is indicative of a flow rate of a fuel; andif a value of the particular signal is not equal to a predetermined setpoint, calibrating the valve and repeating the foregoing steps.
