为E1等级砝码配套的20kg全自动多量程电子天平

摘要

The balance with 20 kilogram capacity is introduced. Some peculiarities and its'efficacies are b'sted such as the balances load at the same time,arm invariableness,self-centering,weights automatic exchange. The balance and the weights of class E, are used to calibrate weights of class E2. The measurement results uncertainty of the system is assessed and verified.%介绍了一款全新的20kg全自动多量程电子天平.通过同步加载、刀子刀承不脱离、自动定心、砝码自动交换及自动检定等创新技术的应用,该天平能作为E1等级砝码的配套天平.通过试验分析了利用该天平配合E1等级砝码校准E2等级砝码的校准结果的不确定度评定及验证.
