Abstract
A testing device () is configured for testing a gas guide element (). A control unit () carries out a sequence of steps with two operating states. A test gas () is delivered by a pumping device () through the gas guide element () to a remotely located measuring location () and is subsequently delivered from the remotely located measuring location () to the gas sensor system (). Measured values () are detected and analyzed during the delivery from the remotely located measuring location () to the gas sensor system () by a sensor (), which indicates a state of flow in the gas guide element () or an operating state of the pumping device (). Changes occurring in the measured values () during the delivery from the remotely located measuring location () to the gas sensor system () indicate the operational capability of the gas guide element ().
