The pendulum impact tester is mainly suitable for measuring the impact property of plastic film, thin film, composite film, metal foil and other materials. The concrete experimental steps are as follows:

1. The pendulum type film impact tester connects the instrument power, opens the power switch, the display screen enters the test interface, and the printer indicator lights on.

2, the display shows the test results energy, calibration angle, and state, range and other options.

3, the test range is selected, the weight is 1J without weight, the weight of 500g is 2J, and the weight of 1000g is 3J. After the weight is replaced, the relative measure range is selected according to the quantity key. This test takes 2J as an example.

4, connect the gas source, ensure that the gas pressure is about 0.6MPa, will be raised clockwise, press the cursor key, the release lever will pop up and place the pendulum on the release lever.

5. The pendulum impact test machine adjusts the balance of the instrument. The pendulum is placed once by placing the pendulum key. After stopping the calibration key, the screen shows the balance angle. If the display is zero, it does not need to be adjusted, otherwise it will be adjusted to zero.

6, a number of 100 x 150mm samples were cut.

7, raise clockwise, press the cursor key, release the lever, and put the pendulum on the release lever.

8. Press the confirmation key to talk about the lifting of the jig, place the sample in the fixture, then press the confirmation key to talk about the clamping of the sample.

9, press the test key, the pendulum falls down, breaks through the sample, the screen reveals breaks the energy, is the test result;

10. Press the print key to print the current test results and replace the sample to continue the test.

11. After the test is finished, turn off the power switch, cut off the power supply, and keep the instruments and accessories properly.
