3.3VT1200 Control Panel
LED display for blade feed rate and amplitude
Setting dial 1, for blade feed rate and amplitude
LED display for section thickness and section thickness addition
Setting dial 2, for section thickness and moving the specimen vertically
Selects the step size in 1μm,10μm or 100μm increments
Quickly moves the speci- men upwards (press the button until the desired position is reached)
Quickly moves the speci- men downwards (press once to adjust to the lowest position)
Press this button (for approx. 3 sec.) to save a frequently used feed value (pressing it more than once feeds by the saved section thickness multiple times)

Caution: Press the button until the desired position is reached. When the end position is reached, the LED lights up.
LED for feed rate
LED on, for enabled amplitude adjustment
Toggles between SPEED (blade feed rate) and AMPL (amplitude)
Section thickness
Sets the current specimen position between 0 (lower) and 20,000μm (upper) or – after zero, totals the section thicknesses
Pressing this button toggles between μm and ∑μm (actively illuminated)
Resets the section thickness addition display ∑μm to zero
Immediately starts or stops the sectioning process

The Leica VT1200 is a semiautomatic microtome with a vibrating blade. Before each cut, a manual feed to the desired section thickness must be carried out using the setting dial for section thickness. The VT1200 does not include an automatic specimen retraction; however, retraction can be performed manually.
