Introduction Haze and turbidity are critical parameters in evaluating the optical clarity and quality of various materials, including glass, plastic, and liquids. These parameters are particularly significant in industries like automotive, construction, packaging, and pharmaceuticals, where transparency and consistency are vital for functionality and aesthetics. This article explores the concepts ...
Abstract: This paper focuses on the electromagnetic compatibility (EMC) testing of power cords and internal connectors in the context of high energy transient interference caused by natural lightning surge induction and large capacity load switching. The LISUN SG61000-5 Surge Generator is introduced as a key tool for conducting such tests. The working principle, specifications, and application sce...
Uncertainty and Errors When measuring physical quantities like length, weight, or time, mistakes can occur during the measuring process, affecting the results. These mistakes are called errors. Errors can be caused by various factors, such as faulty measuring tools, human error in reading measurements, or issues with the measurement system. For example, if a thermometer is malfunctioning and shows...
Abstract: XRF fluorescence, or X-ray fluorescence, is a non-destructive analytical technique used to determine the elemental composition of materials. By analyzing the characteristic wavelengths emitted by different elements when exposed to X-rays, instruments like the LISUN EDX-2A RoHS Testing Equipment provide precise and reliable results. This paper delves into the principles, applications, and...
Due to the various types and appearances of large luminaires, such as LED street lights, floodlights, panel lights, etc., it is difficult to fix the luminaires in a traditional integrating sphere when doing 4π testing. Because there is no test base (platform) to hold so heavy LED outdoor lighting fixtures. LISUN IS-*MA Optical 4π Geometry Integrating Sphere With Holder Base is designed for th...
Abstract Electrostatic Discharge (ESD) is a critical concern for the reliability and durability of electrical and electronic equipment. The ESD testing gun is an essential tool to assess the immunity of devices against static electricity. This paper explores the principles, applications, and benefits of ESD testing guns, with a specific focus on the LISUN ESD61000-2 ESD Simulator Guns. Key paramet...
