Because it can damage the slide or the objective lens and it can cause the specimen to go out of focus.
Explicación
## Step 1The coarse adjustment knob on a microscope is used to make large adjustments to the focus of the specimen. This is done by moving the stage or the objective lens.## Step 2When using high power objectives, the depth of field is very shallow. This means that even a slight movement can cause the specimen to go out of focus or even damage the slide or the objective lens.## Step 3Therefore, it is recommended to use the fine adjustment knob when focusing under high power. This allows for more precise adjustments without the risk of damaging the slide or the objective lens.
