Universal testing machine is a commonly used material testing instrument, which can be used for tensile, bending, compression, shearing and other tests of metal materials and non-metal materials. So, is the universal testing machine easy to operate and is it very complicated? Let's understand the operation steps of the universal testing machine together.

1. Turn on the main switch.
2. Select the measurement range according to the sample, hang or remove the swing pin on the swing bar and adjust the handle of the buffer valve to align with the marking line.
3. Put the corresponding chuck into the upper and lower jaw seat according to the shape and size of the sample.
4. Roll the recording paper on the drum of the tracer.
5. Start the oil pump motor, unscrew the oil delivery valve to raise the test table by 10 mm, and then close the oil valve. If the test stand is already in the raised position, you do not need to open the oil pump to send oil first, and only close the oil delivery valve.
6. Clamp one end of the sample into the upper jaw.
7. Rotate the oil pump to adjust the pointer to the zero point of the dial.
8. Turn on the lower jaw motor, lift the lower jaw to an appropriate height, and clamp the other end of the sample in the lower jaw. Care must be taken to make the sample vertical.
9. Lower the drawing pen on the putter into drawing preparation state.
10. According to the loading speed required by the test, slowly unscrew the oil delivery valve for loading test.
11. After the sample breaks, close the oil valve and stop the oil pump motor.
12. Record the measured value.
13. Open the oil return valve and set the passive needle to zero after unloading.
14. Remove the fractured specimen.
15. Clean up the instrument.
