__________________
The inspection/check procedure of electrical circuit includes two different operations:
-
a fast inspection, which includes a visual examination of all visible components without component removal.
-
a detailed inspection during which components are removed. Thus you can see the other components which are behind and do a detailed visual inspection of all components of the system.
