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.
