Detailed explanation-1: -Low power objectives cover a wide field of view and they are useful for examining large specimens or surveying many smaller specimens. This objective is useful for aligning the microscope. The power for the low objective is 10X.
Detailed explanation-2: -Why do you need to start with 4x in magnification on a microscope? The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.
Detailed explanation-3: -Focusing Specimens: Plug your microscope into the power supply and switch on the illuminator. 2. Always start with the stage as low as possible and using scanning objective (4x).
