6. After checking out the settings mentioned above, press the “ START” button to start the
operation of the machine. During the operation, the current centrifugal force can be displayed on the
window by pressing the “ RCF” button, or touching the screen and clicking the RCF icon.
Repress the button, and the rotating speed value can be displayed again.
7. When counting down to 0, the centrifuge machine stops working automatically. During the
operation, pressing the “ STOP & OPEN” button can also stops the operation of the machine.
When the rotating speed reaches 0, the buzzer would make a buzzing sound, and the cue words
would be displayed on the window. The faceplate can be removed.
8. When press the “ IMPULS” button and hold for a few seconds, the rotors would start
rotation slowly; when the rotating speed reaches its fastest speed, the rotors would not accelerate the
speed any more. When relax the “ IMPULS” button, the rotors begin the deceleration until they
stop rotating. During the deceleration process, the “ IMPULS” button cannot be pressed any
longer; when the rotors stop the rotation completely, the centrifugal process would restart by pressing
and holding the “ IMPULS” button.
9. After the rotors stop the rotation completely, press the “ STOP & OPEN” button to uncover the
faceplate (if the faceplate could not be removed because of its high rebound force against the seal
ring on top of the centrifugal chamber, please press the faceplate slightly with one hand and repress
the “ STOP & OPEN” button with the other to open the faceplate), and take out the
centrifugal tubes carefully. The whole separation process is done.
10. Turn off the power switch, and cut off the power of the centrifugal machine.
07 Safety Notice
1. This machine should not be used in the humid places with high temperature and large fugitive dust.
2. To ensure the safety and its centrifugal effect, this machine should be placed in the solid, quake
proof and horizontal platform, and all four undercarriages should be given the balanced load.
. The solutions in the centrifugal tubes should be seen as even as possible. If the solutions in the
tubes vary too much, there would be a large scale of vibration. In this kind of situation, the operating
machine should be stopped its operation and checked to meet the requirement of the solutions in the
tubes. The centrifugal tubes should be placed symmetrically in the even numbers, and the nut caps
connecting the rotors with the motor shaft should be tightened.
4. During the operation process, the centrifugal machine cannot be moved, and the faceplate cannot
be uncovered.
5. The faceplate should not be uncovered in the situation that the motor and the rotors do not stop
