MODE switch The MODE switch serves to toggle between the manual, single and
automatic modes.
Switch position: MANUAL
• The instrument works in manual mode only; the LED display is not
illuminated. The section thickness must be adjusted using the sec-
tion thickness setting wheel ( Fig. 3 ).
Switch position: SINGLE
• Only one section can be created at a time.
• Using the THICKNESS switch, you can adjust the desired section
thickness; the value is shown in the LED display.
• The user must press up on the directional switch to start another
section. The instrument will retain the desired section thickness.
Switch position: AUTO
• Using this switch position, you can activate the automatic section-
ing mode of the instrument. In automatic sectioning mode, the oper-
ator can set the desired section thickness and number of sections.
The Vibratome carries out the task automatically. This is a great
benefit for serial sectioning.
• The desired section thickness can be configured using the THICK-
NESS switch and the number of sections can be configured using
the SECTION switch. The respective value appears in the display.
The automatic switch also serves as the reset button in auto-
matic mode. If you want to reset the instrument in serial sec-
tioning mode to the default parameters for sectioning opera-
tions and section thicknesses, the counters can be reset using
the automatic switch.
