The value showing on the four-digit display is adjustable.
When the
Σ-µm
LED
is lit, the display shows the sum of the
section thicknesses in µm for all sections completed since the instrument
was switched on.
When the
Σ-n
LED
is lit, the display shows the number of all
previously completed sections.
• To change the display mode, push
MENUMODE
the LED of the desired mode is illuminated.
• Press
CLEAR
to reset section thickness sum or section
number.
• This will only reset the currently displayed value.
Tip
When the instrument is switched off using the main power switch, both values (section thickness
sum and section number) are erased from memory.
Specimen retraction
To prevent damage to the knife and specimen, the specimen is moved away from the knife during the
return motion to the upper home position of the object head.
In motorized sectioning mode, the retraction depends on the setting of the sectioning speed.
In manual mode, the retraction value can be selected in 5 µm increments between 5 and 100 µm.
Specimen retraction is set to 10 µm at the factory.
The specimen retraction can also be deactivated for the manual and motorized operation if required.
The selected setting is maintained when the instrument is turned off.
