The invention relates to a method for functionally testing turbomachines, preferably exhaust gas turbochargers (1, 2, 3), wherein one or more gas pressure pulses is/are applied to the test item and the test item is thereby operated. For a simple, economical, and nevertheless indicative test, the test item (1, 2, 3) is thereby integrated in a test device and at least one gas pressure pulse, preferably at least one compressed air pulse, is applied to the test item by means of said test device, wherein all types of errors are determined from the dynamic behavior of the test item (1, 2, 3) resulting therefrom. |
