Screen 4: Nosepiece (i.e., objective) Z-control or stage X-Y
control.
Z-mode:
The Home position is the highest point to which
the nosepiece can currently be raised. It is usually set at
the upper limit of travel of the nosepiece. The Focus Stop
position is the approximate focus position (actually, a
little above) for the 10x objective. Both positions are
indicated by – marks. The current position of the
nosepiece is indicated by the = mark and its distance
from the Focus Stop is indicated in mm on the display.
Press and hold the Home button to raise the nosepiece to the Home position. Press and
hold the up/down button to move the nosepiece to any position.
Note that this button will allow
the nose piece to travel below the focus position. Careless use of it may drive the objectives into
the specimen.
The Home and Focus Stop positions should not normally be modified. See the section
below for a procedure to set or re-set them.
X/Y Mode:
When X/Y mode is selected, the sensitivity of
the X-Y control knobs can be selected (coarse or fine).
Positions in the X-Y plane can be stored for future use.
Maintained touch in the screen will cause the stage to
translate to that position.
If the condenser is installed,
be sure to lower it first.
Screen 5: Allows programming of any of the black
buttons for specific functions or combinations of
functions
. See us before you program any of them

Screen 6: Not normally needed by users.
