1. Regarding digital load cells At the end of the last century, digital load cells were all the rage. Almost all major foreign manufacturers launched digital load cells. Especially the column-type load cells can install integrated circuits in the casing and directly output "digital signals" to form a complete "digital load cell". However, most strain load cells cannot integrate integrated circuits...

Fraudulent practices involving electronic price-computing scales have a long history; such cheating emerged alongside the widespread adoption of these scales in China, clinging to the devices like a virus. The practice has now evolved into its most sophisticated form—software-based fraud—creating a scenario where the "devil" seems to constantly outpace the "priest." This type of software fraud is ...

I. Overview Currently, there are two different understandings of "repeatability tests". One is a more conventional understanding, which is the ability of a weighing instrument to provide consistent results when the same load is repeatedly applied under relatively constant test conditions using the same operation method. This relatively constant test condition includes: the same weighing procedure,...

I. Overview In the International Recommendation R76-1 "Non-Automatic Weighing Instruments", zero point and zero setting are regarded as very important issues. Not only are metrological requirements put forward for them, but also technical requirements are stipulated, because the stability of the zero point of any weighing instrument is the basic guarantee of its metrological performance. The follo...

An electronic balance is an instrument capable of accurately measuring the mass of an object, and is widely used in fields such as research, pharmaceuticals, chemistry, and food. During actual use, the measurement results of the balance are often affected by various factors, among which temperature and humidity are the most common and significant factors. Understanding the impact of temperature an...

Since ancient times, measurement and weighing systems have not only been symbols of fairness and impartiality, but also the cornerstone of commercial credibility. Electronic weighing scales, as indispensable measuring tools in daily transactions, the accuracy of their measurement values directly affects the livelihood of society. Currently, a large number of experts and scholars have conducted res...
