THICKNESS switch The THICKNESS switch defines the desired section thickness for au-
tomatic mode in microns.
• The parameter selected for this value is indicated in the LED dis-
play above the switch, the displayed values are specified in µm.
The LED (53) in the switch is then illuminated.
Switch position:
Upwards --> Values for the section thickness are increased.
Downwards --> Values for the section thickness are decreased.

SECTION switch

Using the SECTION switch, the number of sections required for auto-
matic mode (AUTO) are defined.
• The value selected for this parameter is indicated in the LED display
above the switch; the LED (54) in the switch is then illuminated.
Switch position:
Upwards --> Number of sections is increased.
Downwards --> Number of sections is decreased.
• If this parameter is set to the value ‘000‘ manually, the instrument
switches to single sectioning mode until automatic mode is deacti-
vated via the switch.
Additional control operations available in automatic mode
• After the automatic sectioning process starts, after each section,
the LED display shows the number of sections remaining, based on
the value defined for the number of sections.
• If both switches, THICKNESS and SECTION, are pushed upwards
or downwards simultaneously, the specimen stage is moved up or
down to the maximum or minimum height position. When this posi-
tion is reached, the LED (54) in the THICKNESS switch flashes.
