10本计算机是专门用于试验机控制和数据处理的，请勿在计算机内安装其它应用软件，以免试验机应用软件不能正常运行。

11计算机要严格按照系统要求一步一步退出，正常关机，否则会损坏部分程序，导致软件无法正常使用。

12不要使用来历不明或与本机无关的软盘在试验机控制用计算机上写盘或读盘，以免病毒感染。

Precautions for switching on/off:

1. The startup sequence of the host and the computer will affect the communication initialization settings of the computer, so the user must strictly follow the above startup sequence.

2 Warm-up for 5 minutes after each startup, and the test can only be carried out after the system is stable.

3 If the machine is just started and needs to be restarted, at least 1 minute interval shall be guaranteed.

4 After replacing the fixture, first pay attention to adjusting the adjustable retaining ring (upper and lower limit switch).

5 Especially when using small force sensor for test, the position of adjustable retaining ring must be adjusted to avoid damage to small force sensor due to operation error. Do not exceed the rated range of the sensor.

6. Do not plug and unplug the power cord with power at any time, otherwise it is easy to damage the electrical control part.

7 During the test, do not stay away from the testing machine.

8 During the test, do not press other keys on the control box except the stop button and emergency stop switch, otherwise the test will be affected.

9 After the test, be sure to turn off all power supplies.

10 This computer is specially used for the control and data processing of the testing machine. Do not install other application software in the computer to prevent the application software of the testing machine from operating normally.

11 The computer should exit step by step in strict accordance with the system requirements and shut down normally, otherwise it will damage some programs and cause the software to not work properly.

12 Do not use the floppy disk with unknown origin or unrelated to this machine to write or read the disk on the computer used for the control of the test machine, so as to avoid virus infection.

Test steps

1. Tensile test

First, select the measuring range according to the sample, hang the thallium and align the scale line, and adjust the buffer valve to adapt to the measuring range. The second is to turn on the power supply, start the oil pump, open the oil delivery valve, and let the piston rise and fall by 200 mm, twice to three times. Third, let the piston rise by 20mm~40mm, and align the pointer with the zero position. Fourth, adjust and move the beam to the proper position. Close the oil delivery valve, press the "open" and "clamp" buttons of the collet, and clamp the sample. Pay attention to make the sample in the vertical position and in the middle position. Adjust the speed of the indicator plate according to the loading speed required by the test. Fifth, open the oil delivery valve to start loading, so that the rotation speed of the pointer is basically consistent with the speed of the tracking plate. Sixth, after the sample is damaged, close the oil delivery valve, record the test data, set the passive needle back to the zero position, and remove the broken sample. Seventh, repeat the contents of two to six to continue the next experiment.

2. Compression test

First, select the measuring range according to the test block, hang the thallium and align the scale line, and adjust the buffer valve to adapt to the measuring range. The second is to connect the power supply, start the oil pump, open the oil delivery valve to make the piston rise for a section, adjust the pointer to zero, and close the oil delivery valve. Third, start the loading speed indicator, and adjust the indicator plate to rotate at a certain speed according to the loading speed. Fourth, put the test block properly. Fifthly, quickly adjust the oil delivery valve to the corresponding position, keep the pointer and indicator plate rotating synchronously until the test block is crushed, close the oil delivery valve and open the oil return valve. Sixth, record the test data and pull back the driven needle. Seventh, remove the crushed test block. Eight is to repeat the contents from four to eight until all test blocks are completed.
