In a convenience store or supermarket, the payment method is a decisive factor in the customer experience. Employees cannot manually enter each product code like in the old days because it is easy to make mistakes, wasting time and causing congestion at the cashier counter. Handheld barcode scanners solve this problem by allowing each item to be quickly scanned in a split second. Best of all, the data is fed directly into the sales system, eliminating the situation of entering wrong prices or missing items.

When implementing a transmitting and receiving system, the first question that engineers have to solve is: how to prevent the high-power signal from the transmitter from bouncing back and damaging the receiver, while both have to use the same antenna? At first glance, many people think that they can install two separate antennas or use a switch. In fact, the cost, latency and complexity will increase a lot. This is the reason why the signal transmitter is used, because it solves both technical and economic problems.

Light meters (lux meters) are familiar tools in many industries: photography, construction, and work environment control. However, many users encounter problems when the battery runs out quickly or suddenly runs out, causing work interruptions. This is a fairly common situation, and is also the reason why many people often look for tips to optimize battery life.

In the packaging industry, choosing the right equipment often determines the efficiency of operations. There are warehouses that have invested in large machines but after a short time, they leave them unused because the output is not enough to exploit the full capacity. On the contrary, there are also places that use cheap hand-held machines, which are convenient at first but the more they use them, the more they realize that the speed does not meet the demand.

Have you ever been shocked by a slight touch of a metal surface? That is the phenomenon of electrostatic discharge, which is not only annoying but can also damage sensitive electronic equipment. Therefore, anti-static discharge becomes a top priority to protect equipment, ensure safety and work efficiency.

In industrial hydraulic systems, high-pressure hydraulic pumps act as the “heart” of the entire machine. If you choose correctly, you will have a durable, safe and efficient operating system. But if you choose incorrectly, not only productivity is affected but repair and replacement costs also increase significantly. So how to distinguish between high-pressure hydraulic pumps and choose the most suitable product?

In the power supply systems for industrial zones or power plants, medium voltage is the most commonly used type. So what is medium voltage actually and how to measure to know if the source meets the voltage for production or not. EMIN will share more clearly below so that everyone can understand.

Plastic laminating machines are increasingly popular in offices, printing shops or photo services. With the function of preserving documents and images over time, this device becomes a useful tool in daily work. However, to ensure the machine operates stably, produces beautiful finished products and maintains a long life, users need to pay attention to how to use and preserve it right from the small operations.

As a newbie, trying to learn how to use an oscilloscope but don't know where to start? In this article, I share 6 basic, easy-to-apply tips to help you get acquainted faster and use the device more effectively.
