) ROTOR AND ACCESSORY

1. Centrifugal force calculation: Use its speed and radius to calculate force as following
formula.

RCF=(rpm)2 x 0.00001118 x R
R : radius (cm)
RCF : Relative Centrifugal Force ( X g )

2. Sterilizing and cleaning rotor:
Rotor is made of stainless steel or steel or aluminum with high density coating and
highly resistant to corrosion ,but not fit to alkaline and strong acid substance.

Don’t heat the rotor to a high temperature ( 100 ℃℃℃℃ ) to clean or sterilize it.

) INSTALLATION

1. When you take centrifuge out from carton box , please check if there is any scratch ,

press trace or other damage from out look. If yes, please contact local dealer
immediately.

2. Please install the centrifuge on a horizontal and stable table or bench. If not, it will

affect anti-vibration efficiency.

3. Please use power voltage as following range , to avoid electric shock please make sure

to connect ground wire to the ground terminal.

Power voltage Acceptable voltage range

100V / 110V 90V ~ 250V

4. Keep it away from dusty and moist working place.

5. Avoid the same power source from the large electric consumption machine.

6. Not suggest to stop the centrifuge suddenly , to avoide the broken motor.

7. After dismantle or clean rotor, be sure to screw it tightly again.

) OPERATION

1. PROPER SETTING OF TUBE AND SAMPLE

(1) Tubes and sample in use must be arranged in even number. Glass tube must be placed
in carrier, which are positioned symmetrically toward rotor center. If tubes are in odd
number, then put same volume of water in a separate tube and place such tubes into
carrier for dummy purpose.

(2)Tube strength should consider if it can bear speed and centrifugal force or not. If not,

the tube will be easy broken.

(3) When you use hematocrit rotor , please note the tube length should be within 75

mm.

(4) The plastic cushion around hematocrit rotor should connect well with clay tube end,

then put on rotor’s cover.

2. THE PROPER SETTING OF ROTOR’S COVER

After placing the hematocrit tubes well , please turn rotor’s cover tightly by clockwise; when
you finish revolving then open it by counter clockwise.
Caution: The plastic cushion around hematocrit rotor has been used for a period, it is much
better to renew it to avoid tube broken.

3. DOOR LOCK AND COVER

(1) Please close cover tightly, otherwise rotor can not move , cover can not be opened

during rotation.

4

(2) Plug power and switch it on, then press【OPEN】button and 【Manual safe button】 to

open cover.

(3) If power cut off and cover can’t be opened, then use a small rod in more 5cm length to

put into the hole at the right side of centrifuge and press manual safe button at the same
time then cover can be opened.

(1). START: After settle time and speed, press it and rotor rotates immediately. .
5

(2). STOP: for emergency stop.
(3). BRAKE: It is with auto-braking function, when presetting time is due.
(4). OPEN : It is used at speed under 100rpm.
(5). RPM: Press “RPM” / RPM( flash) , adjust ▲ or ▼ then press “RPM” to finish it.
(6). TIME : Press “ TIME”/ MIN (flash), adjust ▲ or ▼ then press “TIME” /SEC

(flash) then press ▲ or ▼ press again TIME to finished.
(7). ▲ INCREASE : to add speed or time .
(8). ▼ DECREASE: to reduce speed or time.
(9). RECALL : to display settled speed and time.
(10). STORE : to remember settled speed and time.
After setting speed and time , press ” STORE” twice. If you need presetting function
first press “STORE” then “PROG” to select demand figure then press “STORE’ .
(11). PROG : one program represents one set of speed and time .
If your want to change specific program then press “RECALL”( flash) then “PROG”

to select demand figure, then press “RECALL” again and “START “.
(12). DOOR LAMP : when cover is open , it lights up.
(13). BRAKE LAMP : when it lights up, it will decrease speed automatically.
(14). IMBALANCE : when it lights up, it is imbalance on rotor and stop running. You

have to press “OPEN” to open cover and check problem.
(15). RUN: it lights up during rotation..
(16). DISPLAY: to show speed , time and settled figure.
(17). Transient centrifugal function : it can reach specified speed in transient time without

speed and time limited.
(18) Unbalance lamp. : the this lamp light, it mean something inside unbalance. Will Auto

stop, should press “OPEN” the check the balance.

(3). Place sample into carrier. ( refer page 5 – setting sample )

6

(4). Close cover.
(5). Set “RPM” and “ TIME” at the desired speed and time separately. (see operation panel function)
(6). Press 【START】, rotor begins to rotate and goes up to desired speed.
(7). Time is up, the buzzer sounds automatically.
(8). Press【OPEN】button then press【Manual safe button】at the same time to open the cover.
(9). Your may change the time when operation, and it’ll be re timer again.
(10) . Microcomputer saft control, , it’ll show any time when speed or time have problems.

(13). Please concerning the speed list on 2-4, to setting the rpm.

Do not over duty at the speed.

Caution:

1. Please refer nameplate function , there are 10 sets of program available to store the desired rpm
and time. When you start to run the centrifuge next time, it will perform the last running program.
These programs don’t disappear at power off and on.

2. During rotation , if you want to change speed or time , then press “ RPM” or “ TIME” and adjust
▲ or ▼ then press “RPM” or “ TIME” to finish it separately.

3. During rotation, please don’t exceed the max. speed (refer page 3 ) of the centrifuge and place
substandard rotor or carrier. The centrifuge is without anti-explosion , don’t use explosive material.

Special Caution:
Please be notice with carefully, Stop to use, if any fissure or rift , Found at face of the
Rotor, even very small it may course the function faul when using continue.

Contact your distributor immediate with above matter. Thank you very
much.

REPAIR

) )

1. Checking before and after operation

Check to see if there is any material or water inside chamber and keep it clean.
Check to see if the rotor is loose or not ; if yes, after screw it then use it again.

Check if cover is properly close and screws fixed or not; if not, then stop it and contact
with local distributor.

 Check if the ground wire is connected well , lamps and switch are available.


2. Daily checking:

Clean stain in chamber, check if there is any scratch, deformation, corrosion on rotor or
carrier. If yes, please contact local dealer for further checking.

3. Yearly checking:

A: Check if “rotor fixing nut” is loose or not; B: and the indication value of speed
meter can match real value or not . if not , please contact local dealer.

4. Cleaning:

When sample is split over rotor or carrier , please use cloth with little detergent to wipe
and dry it. When sterilization is made on rotor or carrier, do not heat it to a temperature
exceeding 100℃.
