Various cheating methods are constantly emerging in the market, and these methods are hidden and difficult to prevent. Trade fairness and measurement security are seriously threatened, and "ensuring after-sales safety" has become increasingly important to customers. The DS9 digital instrument kit developed has become a major highlight at the 2016 China Weighing Instrument Exhibition held in Shanghai due to its outstanding safety performance in ensuring after-sales safety.

The DS9 digital instrument kit comprehensively strengthens the security performance of the system from both hardware and software aspects. It installs and uses active and passive detection, monitors product operation status, records events, and then handles them according to customer preset methods (such as deactivation, alarm, etc.). In addition, the DS8 digital instrument kit utilizes independent data transmission dynamic encryption technology to enhance the security of the data transmission process and increase the difficulty of cracking and decompiling protocols. In order to ensure the after-sales safety of customers, a new electronic seal encryption method is adopted to achieve product specificity by meeting customers' personalized customization needs.

At the exhibition site, there was always a constant stream of people in front of the DS9 digital system demonstration area. Technical personnel gave detailed explanations to customers who came to visit about the various features of DS9, and with the support of handheld encryption devices, conducted multiple demonstrations such as secure encryption, cheating alarm, and scale testing. Many customers expressed that this product has made breakthrough improvements in security performance, representing the current level of anti cheating security performance of digital car scales on the market. Being able to continuously promote and apply *'s technology and products to practice, adhering to the business philosophy of "specializing in instruments, doing well in instruments", meeting customer needs, continuously strengthening research and development investment in the field of instruments, and promoting the more standardized and healthy development of China's weighing industry.
