怎样修正拉力试验机的力值和速度?
如何修改拉伸试验机的力值和速度?
1。
进入计算机程序后,打开校准界面,按测试开始,以标准砝码重量将其挂在上部夹具连接座上,记录计算机显示的强度值,并计算与标准砝码重量的差, 误差不应超过±1%
2.拉伸试验机的速度校正:
1.首先记录机器横臂的初始位置,然后在控制面板上选择速度值(使用标准直钢尺进行测量)。
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%....
