台严雷4318弹簧测力计的使用以及注意事项(不要打乱操作顺序) -
戎钧骅13668108685 ______ 1.观察它的量程,认清它的分度值,选择合适的弹簧测力计(物重不可以超过量程) 2.使用前要检查弹簧测力计的指针是否指到零位置.如果没有指在零位置就需要调零,调零一般方法是通过移动指针来调零;再用手轻轻抖动挂钩,确保与外壳无摩擦;并用标准砝码来检查示数是否准确. 3.被测力的方向应与弹簧测力计轴线方向一致. 4.读数时,视线要与弹簧测力计示数向平(主意物体不要挂太长时间,否则测力计会损坏 5.尽量避免弹簧、指针、拉杆与刻度板间的摩擦. 注意事项:所测物体受到重力(拉力)不能超过量程(弹性限度内).
