摘要

The stand (1) has an application device for applying a load on a device under test (2), and a gear provided between the device under test and a drive. The gear includes a changing unit for changing of transmission ratio of the gear, where the changing unit is provided with a drive-effective control drive, a main connecting rod (5) and a pivot point (10). The changing unit includes an actuator (12) for manipulation of the main connecting rod. A force sensor (15) is arranged in a drive section between the main connecting rod and the device under test.
