METHOD FOR TESTING A GAS SENSOR IN A GAS-MEASURING SYSTEM

A method for testing a gas sensor (5) is based on a gas-measuring system (1) with a test gas source (8) and with a pumping device (9). A predefined quantity of a gas or of a gas mixture is fed in, from the test gas source (8), to the gas sensor (5) over a predefined time and metered. The response of...

Zusammenfassung:	A method for testing a gas sensor (5) is based on a gas-measuring system (1) with a test gas source (8) and with a pumping device (9). A predefined quantity of a gas or of a gas mixture is fed in, from the test gas source (8), to the gas sensor (5) over a predefined time and metered. The response of a measured signal (51) of the gas sensor is determined as a sensor response. Characteristic variables, from which an indicator of the ability of the gas sensor (5) to operate is determined, are determined from the sensor response.
