Steps：
In pic 5 it marked out which parts of the microscope are involved to each step.
①Install and fix lens L to the bottom of the focusing tube.
②Bend the two goose-neck spot lights, make the field of view enough illuminated.
③Loose the Arm V-locker, locate the whole monitor part to a desire height (distance from the lens to
the specimen should be around 90mm to300mm), then fix the V-locker. In order to adjust object
distance more precisely, adjust the height of the secondary bracket. The shorter the object distance is,
the bigger magnification is.
④Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom
out.
