Always observe specimen beginning with the lowest
power objective first.
Focus, then move to a higher power objective,
Use only the fine adjustment knob when using the
highest (longest) power objective.
To reduce eyestrain, keep both eyes open when
looking through the microscope. Also, keep eye a little above
the eyepiece when viewing (less eyelash interference).
To find out the total magnification of the object,
multiply the power of the eyepiece lens (usually 10X) by the power
of the objective.
Do not change from one objective to another without
Clean up all materials when finished.
