Green Circle Talks about Cross-border] Test Principles of Safety Testers

A safety tester is a common test instrument used to test whether an electronic product complies with relevant safety standards and regulations. Its testing principle mainly includes the following aspects.

First of all, safety testers usually test the insulation performance of electronic products. This is very important because good insulation can effectively prevent electronic products from leaking or short-circuiting during use. By applying high voltage, the tester observes whether the insulation of the electronic product can effectively withstand the high voltage to ensure its safety performance.

Secondly, the safety tester will also test the voltage resistance of electronic products. Voltage resistance refers to the ability of an electronic product to function normally under a certain voltage without being damaged. The tester will apply a certain voltage and observe the response of the electronic product to assess whether its voltage resistance meets the safety standards.

In addition, the safety tester will also test the grounding performance of electronic products. Good grounding performance can effectively prevent electronic products from being damaged by natural disasters such as lightning, and at the same time protect users from the risk of electric shock. The tester will apply different currents and voltages to test whether the grounding system of the electronic products is stable and reliable.

Finally, the safety tester will also test the fire resistance of the electronic products. Fire resistance refers to the ability of an electronic product not to cause fire or explosion in the event of a malfunction. By simulating various failure scenarios, the tester tests the fire resistance of electronic products to ensure their safety in case of accidents.

Overall, the testing principle of the safety tester involves insulation, voltage resistance, grounding and fire resistance, etc. Through rigorous testing, it can ensure that the electronic products comply with the relevant safety standards and regulations, thus safeguarding the safety of users.
