Argon arc tester precautions

When using an argon arc tester, please pay attention to the following points:

1. It must be ensured that all circuits of the argon arc tester are well connected and the shell of the tester is grounded.

2. When testing, avoid high-voltage current from entering the tester to avoid danger.

3. The tester should avoid severe vibration and collision to avoid damage to internal components.

4. When the tester is not used for a long time, the battery should be removed to prevent battery fluid from leaking and corroding the tester.

5. When testing, ensure that the surface of the sample is clean, otherwise the test results will be affected.

6. During testing, the sample temperature should be avoided from being too high to avoid affecting the test results.

7. During testing, contamination on the surface of the sample should be avoided to avoid affecting the test results.

8. During testing, water droplets or other liquids should be avoided on the surface of the sample to avoid affecting the test results.
