Adjusting the Condenser Position and Aperture Iris Diaphragm

}The condenser is usually used in the highest position. If the entire ob-
served field of view is not bright enough, brightness may be improved by
lowering the condenser slightly.
1. Rotate the condenser height adjustment knob 1 to move the condenser
to the highest position.
2. The aperture iris diaphragm ring 2 has an objective magnification
scale (4X, 10X, 40X, 100X). Rotate the ring so that the magnification
of the objective in use faces frontward.
