How to use the vacuum test machine?

Vacuum test machines are usually used to detect the vacuum degree of closed systems. The following are the general steps to use the vacuum test machine: 1. Connect the power supply: Connect the vacuum test machine to the power supply to ensure the normal operation of the machine. 2. Select the test mode: select the test mode as needed, such as absolute stress test or relative stress test. 3. Set test parameters: set test parameters as needed, such as setting test pressure range, test accuracy, etc.4. Connect the test interface: connect the vacuum test machine to the system under test, and usually use the vacuum pipeline connection. 5. Start the test: start the vacuum test machine and start the test. During the test, the machine will record the test data and automatically judge the test results according to the set parameters. 6. Read the test results: After the test, read the test results displayed by the vacuum test machine, such as vacuum degree, vacuum degree change, etc. It should be noted that when using the vacuum test machine, it should be ensured that the machine works normally and meets the required test accuracy requirements. At the same time, when connecting the test interface, it should be ensured that the interface is tightly connected to avoid leakage affecting the test results.
