Attached with the patent specification, can the same part of the same book be marked with only one?

The drawings in the patent specification usually require the same parts in different drawings to be marked with the same reference numerals.

In the same drawing, it's best to distinguish the same parts, otherwise the manual can't describe them accurately, such as ammeter 1 and ammeter 2, which all use 1. How to describe them? Of course, if the examiner doesn't point it out, he can ignore it. Just point it out and change it to a different mark. This is not a material defect. Don't worry!
