7.4 The Function Buttons on the Stand
A number of function buttons are located on
both sides of the stand. These can be broken
down into fixed and variable buttons. The vari-
able function buttons have different functions
depending on the features of the individual mi-
croscope.
Fixed Function Buttons on the Left Side
The TL/IL button (84.1) toggles between the inci-
dent light and transmitted light axis. The contrast
method last used with a given axis is restored
when switching.
The INT buttons (84.3) adjust the light intensity.
The adjustment can be made in coarse or fine
steps. Pressing both INT buttons at the same
time toggles between coarse and fine adjust-
ment. "Intensity fine" will appear in the display
when fine adjustment is selected.
The AP buttons (84.2) for the aperture dia-
phragm and FD (84.4) for the field diaphragm
open and close their respective diaphragms.
Note:
Changes to the light intensity as well as aperture
and field diaphragm settings are stored for the
individual objectives and contrast methods.
