ABSTRACT:
A weighing apparatus is disclosed of the type including a horizontal scale pan carrier connected at one end with a vertical load receiving member that is guided for vertical movement relative to the housing, characterized by the provision of a calibration weight removably mounted on the other end of the pan carrier beneath the scale pan, and a device for raising the calibration weight to an inoperable position relative to the pan carrier arm. In the preferred embodiment, the calibration weight comprises a horizontally arranged U-shaped member the center of gravity of which is arranged below the scale pan. In this manner, a compact and simple arrangement of the calibration weight is provided that furthermore facilitates ease of handling and operation.
