Instruction manual V 1.4 – 02/2007
In sectioning mode the user can select between STEP function (step-
by-step specimen feed) and continuous specimen feed.
When continuous feed is selected, the coarse feed buttons have the same func-
tions as in trimming mode. The STEP function is useful for careful step-by-step
approximation of the specimen towards the blade.
How to activate the STEP function:
• Switch the instrument on while holding the button on the control panel.
(Likewise, to deactivate switch the instrument on while pressing the button
.) While the instrument is initializing, hold the button until the software
version number is no longer displayed (ensure that version number 2.1 was
displayed).
•
Press TRIM/SECT button and select sectioning mode (LED SECT lit)
.
• When pressing a slow-speed coarse feed button (with an arrow) in STEP
mode, the specimen moves towards or away from the specimen by the value
indicated on the display (single step).
• By short activation of a double-arrow coarse feed button, a single step is also
effected in the appropriate direction.
• Longer activation of the double-arrow coarse feed button effects a repeated
feed motion for as long as the button is pressed.
5. Operation
In the trimming mode, the coarse feed buttons operate a continuous
movement as long as the button is held down. The double-arrow button
for rapid coarse feed backward movements has a lock-in function.
• To start the rapid backwards movement (away from the blade) press the
button .
After the button is pressed, the object head is moved to the rear end
position.
• To stop the movement, press any of the four coarse feed buttons.
• The yellow LED (40) in the button flashes while the object head is in motion,
and remains lit continuously when the rear end position is reached.
• Press the button to start the slow backwards movement. The
travel continues as long as the button is held depressed.
• Press the appropriate button to start a rapid or slow forward movement. The
travel continues as long as the button is held depressed.
• During the forwards movement, the yellow LED (41) in the button flashes.
When the front end position is reached, an acoustic signal is heard and the
LED stops flashing and remains lit.
