Electrical and electronic

In many cases, the person measuring the device concludes that it is vibrating strongly because of a wrong display unit. By understanding the nature of each un

In the production environment, the lighting system not only affects work efficiency but also directly affects the life of equipment, power consumption and operator safety. Each type of lamp, from fluorescent, LED to halogen, has its own operating principle and advantages and disadvantages. Carefully analyzing the characteristics of each type will help determine which is the optimal choice for each area in the factory.

When working with electronic devices, you must have heard about connecting an oscilloscope to a computer and wondered why this operation is so popular. This connection helps to expand the ability to observe signals and increase the speed of testing and analysis during work. You will be surprised by the convenience it brings, especially when experiencing devices like Rigol MHO98, one of the newly launched models with many modern features.

Fiber loss is the cause of light signal weakening during transmission, affecting the performance of the entire network system. This article summarizes specific and easy-to-apply steps to overcome fiber loss, helping you maintain a stable network and smoother transmission.

A Handheld Spectrum Analyzer is a device designed to measure and analyze RF signals in a variety of frequency bands.

When using a multimeter to measure electrical parameters, users may sometimes encounter many problems, from small errors such as incorrect display to more serious damage to the device. In some cases, the meter can even explode during measurement. What is the cause and how to handle this situation, especially when measuring ACV voltage (alternating current voltage)? Let's find out how to protect the device and ensure your own safety when operating.

pH is the foundation of beer’s sensory profile. When maintained within the ideal range, yeast performs consistently, fermentation proceeds properly, and natural aromatic compounds such as esters and phenols are formed. These compounds give beer its distinctive aroma, make the bitterness more pleasant, and create a smooth aftertaste.

In optical transmission systems, connectors are the final contact point between devices and fiber cables, and also the most common source of errors. Even a thin layer of dust or a small trace of oil can cause signal reflection, leading to several decibels of loss. Sometimes, an entire transmission line stretching hundreds of meters can lose signal simply because a connector end is not clean. Anyone who has ever installed optical networks, pulled camera lines, or maintained telecommunications infrastructure has likely faced this situation: the OTDR trace looks perfect, yet the signal is still lost. Upon closer inspection, a speck of dust is found right at the connector’s contact core. From such small issues, many engineers have gradually developed the habit of always inspecting and cleaning connectors before performing any operation, considering it a mandatory step in their workflow.

In today's factories and production systems, precise air flow control is indispensable. Air delivered at the correct flow rate ensures efficiency while optimizing energy and operating costs.

Among the devices used for electronic measurement, the oscilloscope is one of the devices that helps us see directly how the electrical signal is happening. Each waveform displayed on the screen is the “language” of the circuit. Understanding the waveform will help us know whether the circuit is healthy or having problems.
