Laboratory mechanical properties test and operation procedures
一、 打开总电源 检查供电电压试验机使用范围之内后电源与试 验机线连接。
First, turn on the power. Check the connection of the power source and testing machine within the use scope of Power supply voltage tester.
二、 先打开试验机开关再打开油泵开关，后检查试验机油泵是否
正常工作。
Second, open the test machine and open the oil pump next, after then check the text machine and pump working normally or not.
三、 夹具夹持试样，先夹住试样一端再使夹具旁的指针指到5-10
亥I」度之间。
Third, clamping fixture hold the sample, first hold one side of the sample to make the pointer beside the clamping fixture point to 5-10 scale.
四、 调节试验机表盘使两指针重合指在开始刻度线上，再夹住试
样的另一端。之后再使试样纵轴与上下夹具中心连线相重合， 并且要松紧适宜，以防止试样滑脱或断在夹具内。
Forth, adjust the test machine dials, make two pointers overlap point to the began ruling, and then hold the other side of the sample. After that make the sample vertical axis and the center line coincide, and degree of tightness is suitable to prevent the sample slipping or broken in the fixture.
五、 打开进油阀使指针每秒钟走一刻度最为适宜，Fs值过后再调
大出油阀到试样断后关闭进油阀同时打开出油阀并记录下
Fs、Fb 值。
Fifth, open filling valve to make the pointer move one ma
