The basic idea of the modular approach is that modules and components can be flexibly combined into a system. Modular parts are designed to be used both individually and in connection with other converters. Components can be separated and recombined, providing flexibility and diversity in usage. In modular design, customization can be done according to needs without significant effort for changes. In this way, the modular approach reduces the complexity of the system. While modularity is not a new concept, it has become increasingly prevalent in various fields such as automobiles, computers, furniture, plumbing systems, and architecture. Modularization has also been gaining traction in industrial measurement systems. Interchangeable measurement probes, converters, and software offer significant advantages for various measurement applications.
