当在电脑上使用拉力机时，如果遇到：点击“测试”按钮后，机台刚运行一会儿，试样才刚受力就停机了这种情况，请将“用户参数设置”->“控制方案”->“测试方法”->“起始判断比例”的值设置得大些，在低于此值时不判断断裂，这样就不会在刚开始试验时就因误判断断裂而停机了
When using the tensile machine on the computer, if you encounter the situation that the machine just runs for a while after clicking the "test" button, and the sample just stops when it is stressed, please set the value of "user parameter setting" - > "control scheme" - > "test method" - > "initial judgment proportion" to a larger value, and do not judge the fracture when it is lower than this value, so as not to judge the fracture at the beginning of the test Shut down due to misjudgment of fracture
因为拉力机系统为一闭环系统，判断系统中哪一部分出现了故障，先要断开系统中的回路，使系统成为一开环系统。如判断传感器信号时候正常，须断开位移传感器的反馈信号，使系统成为开环。这时，从工作站发出一个控制作动器移动信号，然后测量传感器反馈值，重复几次后，当测量到传感器的反馈数据为一个线性变化的直线，判定传感器正常。
Because the tension machine system is a closed-loop system, to judge which part of the system has a fault, first disconnect the loop in the system, so that the system becomes an open-loop system. If the sensor signal is normal, the feedback signal of displacement sensor must be disconnected to make the system open-loop. At this time, a control actuator movement signal is sent out from the workstation, and then the feedback value of the sensor is measured. After repeated several times, when the feedback data of the sensor is measured as a linear change line, it is determined that the sensor is normal.
