35 6. Startup The display shows the current microscope set- tings. The display depends on the microscope’s configuration. In the first column, corresponding pictograms indicate the type of information: con- trast method, magnification, light intensity, dia- phragms, light splitting for photo tubes.
36 6. Startup Variable function keys: A factory preset is performed which fits your mi croscope configuration. The function keys are labeled accordingly, and a separate description of the key occupation accompanies the microscope (“Identification Sheet”).
37 6. Startup However, depending on how the condenser is disassembled and reassembled, it may be nec- essary to re-adjust the condenser in some cases. Therefore, check the condenser centering. The following procedure is provided for the transmitted light-bright field illumination.
38 6. Startup • Open the field diaphragm just enough for it to disappear from the field of view (41d). Caution: Do not adjust the aperture diaphragm. The aper- ture diaphragm is already set optimally for each objective. 6.6. Checking Phase Contrast Rings A B CD Fig.
39 6. Startup If your microscope is equipped for the use of phase contrast, the light rings that fit the objec- tives are built into the condenser. The light rings are already leveled in the factory. However, the leveling should be rechecked. Note: Every objective is assigned its own light ring in the condenser disc.
40 6. Startup • Insert the centering key through the corre- sponding openings (44.1) in the condenser holder. • Turn the centering screws until the dark ring (phase ring in the objective) is congruent with the slightly narrower bright ring (light ring in condenser) (43 c).
