水平是為避免天平不水平而產(chǎn)生稱量誤差。制動裝置主要由開關(guān)旋鈕、開關(guān)軸和偏心凸輪（或連桿）組成。轉(zhuǎn)動旋鈕使凸輪（或偏心連桿）偏轉(zhuǎn)一定角度，即可使立柱中的升降桿上下，通過中刀承將橫梁托起或落下，以開啟或關(guān)閉天平。托盤天平原理——羅伯威爾（Roberval）機構(gòu)秤盤安橫梁兩邊刀上方的盤架上，秤盤和托盤架重心高于橫梁支點。砝碼或被稱物在處于秤盤前后位置時會引起秤盤盤架和橫梁前后傾側(cè)，在處于秤盤左右位置時會引起秤盤盤架的左右傾倒。為克服此缺點，架盤天平采取了中刀、邊刀和加寬刀架的措施，并在結(jié)構(gòu)設(shè)計上采用了羅伯威爾（Roberval）機構(gòu)。在羅伯威爾機構(gòu)中，桿桿AB、A′B′與縱桿AA′、BB′、支柱EE′鉸鏈連接。山一SKC-18MSP,SKC-18MP,
