      彈簧測力計的正確使用方法

       

      彈簧測力計的正確使用方法:

      (1)首先看清彈簧測力計的量程,也就是彈簧測力計上的最大刻度即彈簧測力計的測量范圍.加在彈簧測力計上的力,不能超出這個(gè)范圍.

      (2)認清彈簧測力計上最小刻度值,即每一小格表示多少N,以便用它測量時(shí)可以迅速讀出測量值.

      (3)測量前要把指針調到零點(diǎn),讀數時(shí),視線(xiàn)要與指針相平.

      (4)測量時(shí),要使測力計內的彈簧軸線(xiàn)方向跟所測力的一致,不可用力猛拉彈簧或讓彈簧測力計長(cháng)久受力,以免損壞.
