7.2 Preparation
①
Put the centrifuge on a steady table, and the centrifuge must be 10cm distance from the wall.
②
Set tubes with sample that can be balance, and put them into holes within the rotor.
7.3 Operation Steps:
①
Shut the cover, connect the power. Press the power button on the right first, then press “speed”
key to set your needed speed; press “time” key to set your needed time.
②
Turn on the power ON, the machine starts to run, at this time, time starts reckon by time when the
speed up to your setting speed; when time up to your setting time, machine stop running.
If the machine is working, do not open the cover.
③

8. MAINTAIN
8.1 Please read the manual book before operation.
8.2 If you found test tubes were aging or corroded before using it, please replace them in time.
8.3 The power should have reliable grounding.
8.4 The test tube must be set with sample that can be balance and put into the rotor symmetrically so
as to keep balance.
8.5 You should cut off the power as soon as hearing abnormal noise.
8.6 Don’t remove the machine while it is running.
8.7 Don’t put any goods on the machine cover.
8.8 If the sample density is more than 1.2 g/cm

, you must calculate Max. speed(N) in the following
formula:
N
max
-------- the limit speed
ρ -------- sample density
