Various embodiments in the invention relate to an elevator structure test. Loose joints and other defects, such as manufacturing, installation, wearing and other similar defects, are hard to find. Especially in case of passenger elevator it is crucial to find these defects in order to produce safe elevators. Testing can be done using a special test signal that is formed by combining an excitement signal with movement control signal. The test signal causes purposively pulsating or oscillating movement of the elevator car that deviates from the ordinary movement of the elevator. This movement causes noises from loose joints and other defects. The sources of these noises can then be located and the defects can be fixed.
