When we refer to the "purpose" of an "equipment", we're talking about what the equipment is used for, its function, or the role it plays in a particular process or system. For instance, if the equipment is a microscope, its purpose would be to magnify tiny objects so that we can examine them more closely. If the equipment is a calculator, its purpose would be to assist us in performing mathematical calculations more quickly and accurately.
If you could provide me with more specifics about Figure 1 and the equipment you're referring to, I would be more than happy to help you answer your "questions". Without knowing the exact details of the figure or equipment, it's a bit difficult to provide a clear and accurate answer.
Remember that it's always important to carefully observe the figure or equipment in question, as well as any labels or descriptions that might accompany it. This will provide valuable clues as to the purpose of the equipment.
I look forward to helping you further with your question!
