1. Insert the battery, turn on the power switch, lights
2. Rotate the focus knob counterclockwise to raise the lens barrel to adjust the brightness of the light
3. First take the specimen, the specimen on the slide, you can use another slide cover as a cover glass, because they are children's toy model, not a professional research, so it eliminates some of the links, and then Slides containing the specimen were placed on the stage and fixed to the clamp. The specimen was moved to the middle of the light-transmitting hole. When the slide was placed, the objective lens was moved to the uppermost position.
4 objective lens to 400, it is 400 times the objective, the objective lens to 1200, 1200 times the objective lens
5. Eyes looking at the objective lens, the right hand adjust the height of the lens adjusted to the right position, but do not touch the cover glass, eyes looking at the eyepiece, right hand a little bit up focus, transferred to be able to see a little time to be very subtle The tone, until we can see the details of the observation.
This process of beginners may be repeated several times, until it can be seen, can not be transferred to the right place once, this is originally a child's observation and careful patience experiment, if even parents are not a little patient, get Microscope, put a piece of things to the top of the place just turn the three eyepiece shouting can not see, please do not buy such science experiment equipment!
