7. Startup

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.
