The glow-wire tester is used to simulate the ignition of insulation materials or other combustible components inside equipment that may catch fire due to a hot wire or hot element. Under certain conditions, such as fault currents flowing through wires, component overloads, and poor contacts, certain components can reach a certain temperature that causes nearby parts to ignite. This can be tested t...

SMT IP10T_AL The object o...
Introduction Digital oscilloscopes make it much easier for engineers to gather and display electrical waveforms for analysis, which is a common task for the profession. It is crucial to correctly interpret and analyze waveforms to get a knowledge of the behavior of circuits, which is necessary for solving issues and improving efficiency. This article will take you step-by-step through the process...
LED, as a new type of lighting source, has many advantages such as high efficiency, energy-saving, and long lifespan, gradually replacing traditional lighting sources. However, how can we ensure the light quality and efficiency of LED lights when purchasing them? This requires LED distribution testing and glare rating testing. This article will explore the application of LM-79 Type C Goniophotomet...
Dustproof test chamber is also known as IPX6 dustproof test chamber. With the rapid development of modern technology, electronic products are being widely used in our daily lives. However, due to the delicate circuits and components inside electronic products, they have low tolerance for dust and particles. Therefore, we need to conduct dustproof tests on them during production and use to ensure t...
PREVENTION OF CONTACT WITH LIVE PINS NOTE: Fully recessed socket-outlets that comply with Clause 3.6.4 are deemed to comply with Clauses 3.8.1 and 3.8.2. During normal insertion At any stage during normal insertion of a non-insulated pin plug into a socket-outlet, with the faces of the plug and socket-outlet in parallel planes, it shall not be possible to touch, with the standard test finger (see ...
With the development of technology, LED lighting fixtures have significant advantages in energy efficiency, lifespan, and color temperature. However, at the same time, LED fixtures also have some issues, one of which is EMI. In order to ensure that the EMI of LED fixtures meets the standard requirements, a dedicated instrument called LED fixture EMI Test Machine and EMI Compliance Test Receiver ha...
The constant temperature humidity chamber will cause different levels of damage to the machine and equipment after long-term temperature running-in. Therefore, the following points are common troubleshooting solutions for the constant temperature humidity chamber. 1. When the constant temperature humidity chamber is conducting the high temperature test, if the temperature change cannot reach the p...
