Abstract
A method for testing a gas sensor is based on a gas-measuring system with a test gas source and with a pumping device. A predefined quantity of a gas or of a gas mixture is fed in, from the test gas source, to the gas sensor over a predefined time and metered. The response of a measured signal of the gas sensor is determined as a sensor response. Characteristic variables, from which an indicator of the ability of the gas sensor to operate is determined, are determined from the sensor response.
