5. Operation
Recommendations during operation

Use even numbers of tubes arranged symmetrically (one opposite another) when
loading to give the unit even balance during operation. The opposite tubes must be
filled up equally.

Centrifuge rotors must not be filled over the volume specified by the manufacturer.

Do not fill in the tubes after they have been inserted in the rotor.

Do not use glass tubes or tubes unsuitable for centrifugation.

Rotor must always be fixed securely. Stop the operation immediately by pressing and
holding the
RUN/STOP
►/■ key for more than 2 seconds if any unusual noise occurs
during acceleration, which can be due to improper rotor fixation.

Since some plastic tubes and microtest plates can be damaged at higher speeds,
maximum speed is limited for some rotors. Before centrifugation, select the type of
installed rotor on the display, see
5.4.3 .

5.1. Check the power cable for any signs of damage. Connect the power cable to a
properly grounded mains socket. Set the power switch on the side to position
I (on).
Caution! In model LMC-4200R , cooling system requires some time for start-
up. After powering up, wait for about 4 minutes before centrifugation.
5.2. The centrifuge turns on. The following readouts appear on the display:
-
Acceleration and deceleration modes (fig. 4/2 or 5/2);
-
Rotor selection (fig. 4/1 or 5/1);
-
Set rotor speed in RPM or RCF
1
(fig. 4/6 or 5/6);
-
Set chamber temperature, in degrees Celsius (only LMC-4200R , fig. 5/7);
-
Status icons of rotor, ■ stopped or ► running (fig. 4/1 or 5/1, first symbol);
-
Status icons of lid, closed or

open (fig. 4/1 or 5/1, second symbol);
-
Set time of centrifugation, in minutes and seconds (fig. 4/4 or 5/4);
-
Actual rotor speed, in RPM or RCF (fig. 4/6 or 5/6);
-
Actual chamber temperature, in degrees Celsius (only LMC-4200R , fig. 5/8).
