6.1 Functional Principle
The microscope’s most important functions may be easily accessed using function keys.
The microscope may be switched between various contrast processes by pressing a single button.
The microscope recognizes the objective chosen and the respective contrast process. There-
fore, the values for intensity (INT), aperture diaphragm (AP) and field diaphragm (FD) are al-
ways set correctly.
The values for INT, AP and FD can be changed individually. This overwrites the previous
setting. Actual settings are stored automatically.
The specifications for INT, AP and FD always relate to the currently activated light axis (trans-
mitted 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:
These function keys are assigned logical functions before delivery(see “Identification Sheet”)
These functions can be reprogrammed according to your individual wishes.
Note: (Reset-Function)
The microscope can be reset to the default functions programmed at the factory:
When the microscope is switched off, press all 3 variable function keys on the left stand
section.
Switch on the stand.
Hold the keys pressed down until initialization is complete.
The standard information is shown in the display.
Switch off the instrument and switch it on again. The settings are stored now.
6.2 Switching on the Microscope
First, swivel the objective with the least magnification into position.
