Precautions for friction voltage test
With the development of technology and industry, the awareness of static electricity in all walks of life is gradually becoming stricter. Anti-static products can effectively discharge human body static electricity or neutralize static charges, effectively preventing the harm caused by static discharge. Before purchasing general anti-static products, customers will require anti-static product manufacturers to issue a third-party (national testing center) test report. Friction voltage test method: A. Ensure that the two tested objects and the surrounding environment are not charged before the test; B. The friction process will not be affected by other external objects; C. Take tools (tweezers, gloves, etc.) and the workbench will not affect the test The static electricity level; D, static electricity can be maintained for a certain period of time, so that the data can be read. The precautions for the friction voltage test are as follows:
1. The instrument must be correctly calibrated and reset to zero;
2. The correct distance between the electrode and the measuring surface;
3. Correct grounding;
4. The human body is grounded and discharged when the operator uses it;
5. The surrounding environment of the measured object, the measurement activity will affect the measurement result
