When placing the rotor, ensure the full contact between the rotor and the main shaft.

Load the rotor on to the shaft to ensure rotor is in position until it is well connected to the main shaft.

If the rotor is loaded properly on the shaft, you will feel a “click” sound otherwise it is understood that

the rotor is not secured properly on the main shaft. Check once again and if necessary clean it again.

Rotate the rotor slightly with your fingers to check if the rotor vibrates, if so attach the rotor again.

Rotate the nut clockwise using the wrench to tighten the rotor to the shaft firmly.

Rotate the rotor lid in clockwise to the rotor and close  the  rotor  lid and  ensure  t h a t  i t   is  in position.

Close  the centrifuge lid and start operation.

Remove the rotor after operation same as above by turning the locking nut counterclockwise.

8.1.2 Set operating parameters 

Press  the  select  button 

  gently  to  select  the  parameters  and  set  the  parameter  values  to  desired 

setting.  Use  the  parameter  adjustment  knob 

  to  set  the  selected  parameters  (whichever  parameter 

icon flashes). Rotate the parameter adjustment knob in clockwise/anticlockwise direction to increase or 

decrease the parameter values to achieve the desired setting. The minimum speed increment is 10rpm, the 

minimum time increment is 1 second. 

(1)

 

Set the rotation speed

Press the select button

to select the rotation speed in rpm. 

The speed value flashes indicating that the speed is in adjustment mode

The minimum set speed is 500rpm, and the minimum step is 100rpm.

Turn  the  parameter  adjustment  knob

clockwise/anti-clockwise  to  increase/decrease  the 

parameter value. 

(2) Set the running time

Press the select button

to make the time value flash and enter into the time setting mode. 

Turn the parameter adjustment knob

to input the set time within a range of 10sec-99min. 

The centrifuge enters into continuous run mode if the time indicates HD.

Caution

 

Place the rotor on the main shaft and ensure full contact between the rotor and the main shaft. Screw

up  the  nut  on  the  rotor  tightly  using  a  wrench  to  connect  the  rotor  with  the  main  shaft  firmly,

otherwise the rotor might fall off, causing damage to the centrifuge.

Tighten the lid and rotor firmly.
