Leica VT1200 and VT1200 S – Microtome

5.2 Control Elements on the VT1200 Control Panel

Caution: To practice the key functions, always make sure there are

no blades installed! Do not install the blades until you are familiar

with all of the key functions.

When the instrument is switched on, to make it easier to insert a specimen,

the specimen receptacle automatically moves into the lowest position

(the LED in the DOWN key lights up) and the blade holder moves into the

rearmost position (the LED in "Blade away" from the specimen lights up).

The last parameters used before the instrument was switched off are called

up again: blade feed rate (SPEED), selected amplitude (AMPL) and the sec-

tion thickness that was saved using the MEMO key.

The LED illumination is switched on automatically. You can switch it off using

the ON/OFF key (lamp symbol).

5.2.1 Moving the Specimen Receptacle Vertically

When the DOWN key is pressed, the specimen receptacle automatically

moves quickly into the lowest position. (The LED in the DOWN key lights up

when the lower end position is reached.) The ∑μm display is set to "0". If the

DOWN key is pressed a second time while the specimen receptacle is mov-

ing downwards, the specimen receptacle comes to a stop. The current

position appears on the ∑μm display (lowest position = 0). The ∑μm display

does not change while the specimen receptacle is in motion.

When the UP key is pressed and held, the specimen receptacle moves quickly

upwards into the desired position. After the UP key has been released, the

current position of the specimen receptacle appears on the ∑μm display.

If the specimen receptacle reaches the upper end position, the LED in the

UP key lights up (uppermost position = 20,000μm). The ∑μm display does

not change while the specimen receptacle is in motion.

You can reset the display for the current position of the specimen holder to

zero at any point using the CLEAR/∑μm key. The section thicknesses are

then added in the ∑μm display. Switch to μm by pressing the μm/

∑∑

∑μm key.
