The invention relates to a calibrating unit for performing greatly differing calibrating procedures with greatly differing gases on a mobile exhaust-gas measuring device in the simplest manner possible. Said calibrating unit comprises a number of inlet connections (11, 19), which lead into at least one inlet line (21), to which an overflow line (28) is connected, wherein the overflow line (28) is connected to an overflow outlet connection (13) of the calibrating unit (1) and wherein a response-time line (39) connected to a response-time outlet connection (14) of the calibrating unit (1) is provided, which response-time line is connected either to the overflow line (28) or to an inlet connection (11, 16) of the calibrating unit (1). |
