The static electricity generated by the human body to an object or between two objects may cause the circuit of electrical and electronic equipment to malfunction or even be damaged. Therefore, ESD test widely used all over the world. The electrostatic discharge generator is also known as electrostatic discharge gun is an important equipment in the electrostatic discharge immunity test in the elec...
Introduction Print circuit board (PCB) and electronic component dependability and longevity is of utmost importance in today’s fast-paced, technologically sophisticated electronics sector. Environmental variables such as moisture, humidity, and corrosive substances are common enemies of these parts, and may cause deterioration in performance and early failures. The reliability and resistance...
Gloss meter, also called digital glossmeter, is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials. According to the angle, the precision gloss meter is divided into three types: gloss, medium gloss and low gloss. Gloss is a surface property that can provide important information about surface quality. From building m...
Introduction The need for a robust charging infrastructure is of critical importance as the number of people driving electric cars (EVs) increases. Charging stations for EVs need reliable power supply systems that can keep up with the growing demand and keep the charging process simple and streamlined for EV drivers. Surge testers are an essential component of a secure and reliable power grid and ...
The colorimeter is also called the Handheld Colorimeter. The Handheld Colorimeter is a simple color deviation test instrument, that is, to make a filter that simulates the spectral characteristics equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample. The key is to design the spectral sensitivity characteristics of this photoreceptor, and to measure a...
Introduction Goniophotometry is a very effective measuring method that is crucial to the LED characterisation process. It allows for the accurate assessment of a wide range of photometric and radiometric characteristics, shedding information on the efficacy, output, and spatial distribution of light from LEDs. The importance of goniophotometry in LED characterisation is discussed, with an emphasis...
Introduction When it comes to correctly and dependably measuring color, a wide variety of companies rely on spectroradiometer integrating sphere systems of the greatest quality. The constant illumination and comprehensive spectrum information provided by these devices make it feasible to conduct accurate colorimetry analyses. Nevertheless, the outcomes of the measurements might be influenced by va...
8. Accessibility of Live Parts 8.1 An electrical part of a heater shall be so located or enclosed that protection against unintentional contact with uninsulated live parts will be provided, except that this requirement does not apply to a visibly glowing open-wire element and the connections immediately adjacent to the element. See 3.1, 8.2,32.7 and 32.14. Insulated motor brush caps do not require...
The burst generator is also called burst tester, is a kind of EMI filter, and its name comes from the “Electrical Fast Transient/burst” (abbreviated as EFT) experiment. The EFT experiment is an immunity test experiment, which is divided into four levels according to the IEC61000-4-4 standard. Different levels of EFT generators have different injection voltages or cargo coupling voltage...
