7.1 Functional principle

The microscope's most important functions may be easily accessed using function keys.
• The microscope may be switched between various contrast methods by pressing a button.
• The microscope recognizes the selected objective and associated contrast method. There-
fore, the values for intensity (INT), aperture diaphragm (AP) and field diaphragm (FD) are
always set correctly.
• The INT, AP and FD values can be adjusted individually. Manual adjustments overwrite the
previous settings. The current setting is saved.
• The INT, AP and FD values are always based on the currently activated light axis (transmitted
light or incident light).
• In addition to the preset function keys for INT, AP and FD, there are also variable function
keys.
Variable function keys:
• At the time of delivery, these function keys are assigned functions suitable to the configura-
tion of your microscope.
• However, the functions can be reprogrammed and/or adapted to your specific requirements.
Note: (reset function)
The microscope can be reset to its factory default programming:
• When the microscope is switched off, press all 3 variable function keys on the left stand section.
• Switch on the power for the stand.
• Hold the buttons until the initialization is complete.
• The standard indicator appears in the display.
• Switch the instrument off and back on. The settings are now saved.
