SECTION 3: OPERATING THE MICROSCOPE

3.1: The Specimen Stage

The stage has an adjustable height limit. This is used to prevent the stage from

being raised too high which could result in damaging the specimen or even the

objective lenses. The adjustment screw is located on the body just behind the

stage.

Rotate the objective turret until the 40X objective lens is in place. With a

specimen mounted on the stage, slowly raise the stage using the coarse-focus

knob until the specimen is a few millimeters from the lens. Use the fine focus

knob to continue raising the stage until the specimen barely comes in contact

with the lens. The 40X lens has a spring-loaded nose. If the nose begins to

compress, the stage is too high. When the specimen is able to make contact

with the lens without compressing the nose, this is the appropriate maximum

height.

The height-adjustment screw should be tightened to set the stopping position.

If the specimen was too far from the lens, and could not make contact, loosen

the adjustment screw slightly, then continue to make fine focus adjustments

until the specimen is high enough. Once the height is properly set, tighten the

adjustment screw.

The power switch should be set to the "off" (0) position. Attach the provided

power cable, ensuring that the instrument is not exposed to any environmental

dangers such as moisture or sources of excessive heat such as open flames.

Set the power switch to the "on" (I) position to activate the built-in illumination.

The microscope can also be powered by three AAA batteries. Remove the

bottom cover with a small philips head screwdriver and insert batteries in the

correct orientation. Batteries are not included.

If using rechargeable AAA batteries, the microscope will recharge the batteries

when plugged into an AC outlet using the included power adapter.
