Recalibration Procedure for Speed

:

 

This centrifuge was initially set by its speed from 1000 

– 4500 rpm (or 

4000 rpm for PLC-05) in house.    Supposed that the min/max speed is 
varied, the control can be recalibrated as depicted below

:

 

 

1

 

Remove the bottom plate, switch power on by turning control knob 
of timer. 

CAUTION

:

 Electrical Shock 

2

 Turn knob of speed regulator to the extreme 

LOW

 position. Adjust 

part of SVR P2/204 (for the low 1000 rpm control) right/left to get 
the desired speed of 1000rpm.   

3

 To recalibrate the speed for 4000 or 4500rpm, turn speed regulator 

to the extreme 

HIGH

 position, then adjust SVR (P1/104) right/left 

slightly until it reaches 4000 or 4500 rpm. 

4

 The calibration of LOW or HIGH speed can influence each other; 

thus the user is recommended to use the digital speed indicator 
and measure the result of the recalibration.    Repeat the above 
procedure until the final speed indication meets your requirement. 

5

 Switch off the power and assemble the bottom plate. 

6

 Glue the parts of SVR (P1/104 and P2/204) after the speed 

recalibration is finished.    The transportation and vibration may 
probably loosen the electronic parts and fasteners.   

 

WARNING

:

 

Electric shock and Personal injury. Always proceed with caution.
