Note:
Parfocality has been learned in at the factory.
Mounting the objectives, however, can change
the values so that parfocality has to be learned
in again.
We recommend to check parfocality before
setting the thresholds. If necessary, it can be
learned in with the Software Leica DMControl,
module: Fine Tuning.
Image Focus
You can focus by using the turning knob (66.3)
on the remote control element SmartMove.
Alternatively, you can use the focus wheels on
both sides of the stand.
The current Z-position is displayed on the status
page of the LeicaScreen. When switching on
the microscope, before initialization the z-drive
will automatically go to a position which is 3mm
below the most recently used Z-position.
Setting thresholds
The lower threshold can be set with the
LeicaScreen and with the Software Leica
DMControl.
The
lower threshold
is the same for all
objectives and can not be overrode.
Leica DM6000 B only:
An additional
focus position
, which can not be
overrode, can be set. This position should be set
for the DRY objective with the highest
magnification. For all other objectives it will be
set automatically, regarding parfocality and
working distance.
Setting thresholds via:
LeicaScreen - navigation item
Software Leica DMControl, module: Fine
Tuning
When the thresholds are set, this will be
displayed on the LeicaScreen with the following
pictograms:
lower threshold not set
lower threshold set
focus position not set
focus position not set
Go to thresholds via:
LeicaScreen - navigation item
Variable function keys at the stand and at
the SmartMove
Software Leica DMControl, module: Fine
Tuning or DMOperation
Note:
When using the
UPPER Z
and
LOWER Z
keys to
go to a threshold, the keys have to be pressed
until the final position is reached.
