Abstract:
A stand comprising:an automatic balancing device including an effective lever arm (h), a counterweight (AG) displaceable on said effective lever arm (h), an electric motor (5) operable to displace said counterweight (AG) on said lever arm (h), a sensor (8) arranged to detect an imbalance in said stand, and a microprocessor (12) in communication with said sensor (8) and said electric motor (5) for activating said electric motor (5) according to a software program in response to said imbalance; wherein said software program comprises program steps in which, while said counterweight (AG) is being displaced on said lever arm (h), the detected imbalance at said sensor (8) is ascertained and a signal value thus dynamically detected is used for activation of said electric motor (5), a continuing displacement of said counterweight (AG) by said electric motor (5) being influenced by said activation.
