(2) Illumination setting in the manual mode
If required, the Axioskop 2 mot plus can be
switched to the manual mode. Illumination
intensity and condenser functions must then be
operated manually, as in the Axioskop 2 plus.
The manual mode is set as follows:
• Switch off the microscope with the on / off
switch (3-1/27).
• Press, and keep pressed, the transmitted-light
on / off key (3-14/1).
• Switch the microscope on again with the
on / off key (3-1/27) and wait until beep is
heard after approx. 3 seconds. Do not release
the transmitted light on / off key (3-14/1) until
this beep is heard.
• The Axioskop 2 mot plus is then in the manual
mode.
(3) Setting of parameters for stage focusing in the programming mode
When the parameters for stage focusing are set individually, the focus positions of the various objectives
(parfocality) and the focusing speeds are matched to the appropriate objective magnification.
This is done in the programming mode, which is reached by pressing the Set key for more than 2
seconds.
The focus positions and focusing speeds are normally matched to the objective magnification only when
the microscope is used for the first time or after the change of objectives in the nosepiece. To allow
matching, the microscope must be set in the programming mode via several key functions.
Parfocality between the objectives is factory-set to zero. When matching the focus positions between the
used objectives, always start with the dry objective with the highest magnification factor, since this
features the smallest depth of focus. The focusing speed is factory-set to the maximum value for all
objective positions to facilitate setting.
