怎樣修正拉力試驗機的力值和速度?
如何修改拉伸試驗機的力值和速度?
1。
進入計算機程序后,打開校準界面,按測試開始,以標準砝碼重量將其掛在上部夾具連接座上,記錄計算機顯示的強度值,并計算與標準砝碼重量的差, 誤差不應超過±1%
2.拉伸試驗機的速度校正:
1.首先記錄機器橫臂的初始位置,然后在控制面板上選擇速度值(使用標準直鋼尺進行測量)。
2. At the same time when starting the machine, the electronic stopwatch starts timing for one minute.At the same time as the stopwatch reaches the time, press the stop button of the machine.According to the time of the stopwatch, the value of the travel of the crossarm is the rate per minute (mm / min) The difference between the shoulder travel value and the straight steel ruler, and the calculation of the travel error value of the shoulder, should not exceed ± 1%....
