| 1 | First turn the speed knob (clockwise) to the minimum; |
| 2 | Place the object to be tested on the workbench and use a fixture to clamp it firmly; |
| 3 | Adjust the height of the upper and lower bars to make the distance between the fixtures appropriate. |
| 4 | Adjust the "speed knob" to make the speed meet the requirements |
| 5 | Use the lower clamp to clamp the lower end of the test piece, and raise the lower cross bar to an appropriate distance, then stop the machine, and then use the upper clamp to clamp the top of the test piece. |
| 6 | Turn on the power, start the operation, adjust the experimental schedule, and stop after adjustment; |
| 7 | When everything is ready, press the rising or falling push-pull test to start the test. |
| 8 | Repeat the above operations when repeating the experiment, press the stop switch when you need to stop in the middle, and continue after pressing the start button; |
| 9 | After the test, adjust the displacement to the minimum and the speed to the minimum, and then turn off the power. |
1. When adjusting the displacement, adjust slowly, and the maximum displacement shall not exceed 5CM to prevent impact;
2. Slowly speed up the speed adjustment. If you find that there is an impact sound, you need to reduce the displacement or speed;
