The parameters for stage focusing are set as
follows:
•
Swing in the dry objective with the highest
magnification factor via the nosepiece.
•
Set reflector turret to transmitted-light position
(see 3-1/
23 ).
•
Use fine adjustment for precise focusing on the
specimen.
•
Keep Set key (3-15/ 1 ) pressed for more than 2
seconds until double beep is heard. The
programming mode for the setting of
parfocality and to match the focusing speeds is
now activated.
The pilot lamp on the right of the stand (3-16/ 2 )
lights up alternately from green to orange as long
as the instrument is in the programming mode.
The focusing speed can be changed in 10 steps via
the two keys for fast stage lowering
/ lifting
(3-14/ 2 ).
−
Key : higher speed
−
Key : lower speed
•
The focusing speed can be matched to the
individual requirements by switching between
coarse and fine adjustment (3-14/
3 ) and by
experimenting.
The set speed is indicated on the LED array on the
right of the stand (3-16/
1 ).
•
Then precisely focus on the specimen again and turn the nosepiece to bring the objective with the
next lowest magnification in the beam path.
By turning the nosepiece to the next position, the focus position and focusing speed values set for the
previous position will be stored in the programming mode.
•
Set focusing speed via the current objective, focus precisely on the specimen and store the settings by
turning the nosepiece to the next position.
•
Repeat these steps for all objectives. Oil immersion objectives should always be the last in the row of
settings.
