Abstract: According to the new verification regulation JJG 98—2019 Mechanical Balance, the stable mechanical balance of the laboratory is selected as the measurement object, the measurement model of mechanical balance is established, the source of the uncertainty of the mechanical balance is calculated and analyzed, and the uncertainty of the measurement result of the weighing point is finally obtained.

Keywords: mechanical balance; measuring equipment; uncertainty

目前,機械天平仍然作為計量技術(shù)機構(gòu)和企業(yè)的計量標(biāo)準(zhǔn)器具被使用,特別是在一些安全程度要求較高、需要精密稱量的生產(chǎn)加工領(lǐng)域。(剩余1818字)
