Trial Construction of an Antomatical Calibration Device for Standard Weights

摘要

Establishment of national mass standard by using multiple and submultiple methods based on national prototype kilogram requires very high skilful techniques and years of time. For improving the efficiency, an automatical weight calibration device which does not need the high techniques is being developed. A prototype has been designed and constructed. A set of ring shaped standard weights(1 kg to 100 g) is contained inside and automatically calibrated by submultiple method. Preliminary measurements gave a standard deviation about 0.02 mg.
