6. Startup
There is a row of function keys both on the right and left side of the stand. Some of these keys are defined, and some of them are variable. The variable function keys have various meanings depending on the microscope configuration.
Defined Function Keys on the left side of the stand
The TL/IL key (38.1) switches between incident light and transmitted light. The last contrast method used is restored.
The INT (38.3) keys adjust the light intensity indi- vidually. Settings can be made either in large or small increments. Pushing both INT buttons at the same time switches between coarse and fine setting. The display indicator changes accordingly → p. 52.
The AP (38.4) keys for the aperture diaphragm and FD (38.2) for the field diaphragm are used to set each diaphragm. The optimal values are automatically preset when selecting the con- trast method.
Variable function keys:
A factory preset is performed which fits your microscope configuration. The function keys are labeled accordingly, and a separate description of the key occupation accompanies the microscope (“Identification Sheet”).
Abbreations are listed on p.32f.
6.5 Köhler Illumination
For each objective, optimal values for the aper- ture diaphragm and the field diaphragm are al- ready set. The condenser is also already adjusted in the factory.
