6.1 Setting the radius
When you control the rotational speed via the g-force (rcf, RCF), and not via the speed (rpm), the
internal conversion of speed to g-force takes place by default with the largest radius of the used
rotor (see Rotors on p. 13). You can adapt this radius to an applied adapter:
6.2 Setting the acceleration and braking times
You can set the acceleration and braking time in the levels 0 to 9 (see Tab. on p. 73). Level 9 is
preset (shortest acceleration and braking time).
The device only shows the and symbols continually when levels 0 to 8 have been set.
6.3 Setting the start of run time (At set rpm)
The centrifuge can count down the set time either immediately from the start of centrifugation or
only once 95% of the specified g-force (rcf)/speed (rpm) has been reached (At set rpm). The
respective setting is indicated by the flashing triangle in the symbol above the display:
Prerequisites
The centrifuge lid is open.
When pressing the key, both triangles of the symbol will flash in turn.
1. Press several times until the symbol also appears in the display.
The current radius flashes.
2. Set the new radius.
3. Wait for 3 seconds (if the rotor is stopped: 10 seconds).
The changed g-force appears.
1. Press twice until the symbol for acceleration level (accel) appears in the display.
2. Select acceleration level 0 to 9.
3. Press once until the symbol for braking level (brake) appears in the display.
4. Select braking level 0 to 9.
Braking level (brake) 0 corresponds to free deceleration.
Preset time: the set time is counted down immediately after the start of
centrifugation.
At set rpm: the set time is counted down once 95% of the specified g-force (rcf)/
speed (rpm) has been reached.
 Hold down this key for at least 4 s to switch between the two settings,
