PRACTICAL OPERATION OF A 3 TONS SCALE TESTING ROBOT

W. Kühn, R. Schwartz

Abstract

The automatic deadweight machine at the Weighing Instruments Laboratory of the PTB was designed for testing weighing instruments with a maximal load of up to 3 t under varying climatic conditions. The paper reports on the practical operation of the machine for performing legally mandatory weighing tests according to OIML recommendations R76. In particular, critical interference resulting from the wide temperature range of -10°C to +40°C have to be identified and controlled.
