Step 1: Understanding the Concept: 
Modern large-scale manufacturing refers to the mass production of goods using advanced machinery, assembly lines, and a specialized workforce. It is defined by several key characteristics that distinguish it from traditional or small-scale production. 
Step 2: Detailed Explanation: 
Let's analyze the characteristics listed: 
1. Specialisation of Skills: This is a core feature. In large-scale manufacturing, complex tasks are broken down into smaller, simpler steps, and each worker specializes in one step, increasing efficiency. 
2. Technological Innovation: Modern manufacturing constantly incorporates new technologies, such as robotics, AI, and advanced materials, to improve products and processes. 
3. Mechanisation: This involves the use of machines to perform tasks previously done by hand. It is fundamental to mass production. 
4. Low level capital investment: This is incorrect. Modern large-scale manufacturing is characterized by high capital investment. Setting up factories, purchasing sophisticated machinery, and investing in research and development require enormous financial resources. 
Step 3: Final Answer: 
The characteristic that modern large-scale manufacturing does not have is a low level of capital investment; it requires a very high level of capital investment.
