USER MANUAL
Centrifuge CM-7S Plus
Operation
ENG
Place the test tubes in the rotor adapters . Always
load the rotor symmetrically by minimizing weight
difference between filled test tubes, you reduce the
wear on mechanical parts of the centrifuge . The
total imbalance of test tubes should not exceed 7
grams .
For safety reasons, the centrifuge lid automatically
locks when closed and unlocks at the end of cen-
trifugation cycle . T he lid can be unlocked with the
OPEN button, but only with the rotor at a standstill .
Settings and adjustments to the parameters of the
centrifuge must be made before the start of the
centrifugation cycle, with opened or closed lid . Dur-
ing the centrifugation cycle, only the RPM (RCF) pa-
rameter can be adjusted .
1. Setting rotor rotation speed/G-force param-
eter: Select the RPM/RCF parameter with scroll
keys and set the needed value with tuning keys .
Braking levels have the folowing parameters

ATTENTION! Operation must be stopped immediately if there are any unusual noises or vibration.
ATTENTION! Check the rotor and rubber seal for wear each time before starting the centrifuge.
2. Setting time parameter: Select the time pa-
rameter with scroll keys and set the needed val-
ue with tuning keys .
3. Unlocking centrifuge lid: Unlock centrifuge lid
by pressing the OPEN button . For safety rea-
sons, pressing this button during centrifugation
will have no effect. After the end of centrifuga-
tion cycle, the lid unlocks automatically .
4. Starting the centrifuge: Close the centrifuge
lid and start the centrifugation cycle by pressing
the START/STOP button .
5. Stopping centrifuge before estimated time
runs out: To stop the centrifuge before the end
of centrifugation cycle, press the START/STOP
button .
6. Setting braking level: To set the desired brak-
ing level, enter the settings menu and select a
value from 1 to 6 .
