Abstract

A method for operating a test station (10) for portable gas-measuring devices (20) is provided. The gas-measuring device (20) is arranged in fluid-communication with the test station (10) via at least one interface (13). A flow time is set, during which the test gas (30) is fed and a waiting time is set, during which no test gas (30) is fed. After an end of the feed of the at least one test gas results of the test are analyzed. The test station (10) is configured for feeding at least one test gas (30) to the interface (13). The test station (10) for portable gas-measuring devices (20) has at least one interface (13) for the fluid-communicating arrangement of the gas-measuring device (20), and wherein the test station (10) is configured for feeding at least one test gas (30) to the interface (13).
