When these keys are pressed simultaneously, the display switches from
rpm to rcf (and vice-versa).
If this takes place during the run, the display switches back after
20 seconds.
In order to determine the RCF for the displayed rotational speed of the MiniSpin, you can
calculate with the following formula in accordance with DIN 58 970:
rcf = 1,118 · 10 -5 · n 2 · r
max
n: rotational speed in 1/min
r
max
= 6 cm : max. centrifuging radius in cm
Example: Because the maximum centrifugation radius is 6 cm, a maximum RCF of 7,000 x g
can be achieved at a rotational speed of 10,200.
Disconnect the centrifuge from the mains supply. Wait until the rotor
has come to a standstill. (This may take up to four minutes!)
Then lift up MiniSpin, insert a pen into the opening in the ground plate and move the
disc in the direction of the arrow (see Fig. 1, E).
When lifting up the centrifuge, particularly after a device failure, please note that the
motor on the underside of the centrifuge can become uncomfortably hot. Touch the
device at the edges only!
