C.    Loosen the locking screw and move the location screw forward or 

backward to make the image of filament be in the center of paper; 

D.    If the image of filament not clear, you should adjust the condenser 

adjusting handle to make the image clear; 

E.    If  the  image  of  filament  offset  the  center  of  stage  too  far,  you 

should adjust the screw 3 and push it to side a little; 

F.    Install the 10X objective  and  put  a  piece of  specimen on  the stage 

again; 

G.    Adjust  the  coarse/fine  focusing  knob  to  make  the  image  of 

specimen clear; 

H.    If  brightness  of  field  not  equality,  you  can  adjust  the  screw  3  or 

move the lamp 2 slightly to make the brightness of field equality; 

I.    Turn  the  field  diaphragm  to  minimum,  adjust  the  field  diaphragm 

adjusting  screw  to  make  the  center  of  field  diaphragm  and  field  be 

superposition,  then  turn  the  field  diaphragm  until  you  can  not  see  the 

image of field diaphragm in the field;(Fig.2) 

J.    When use other magnification objective, you can adjust the aperture 

diaphragm  and  the  brightness  of  illumination  to  obtain  satisfactory 

contrast; 

K.    In order to obtain an image of good quality, you can use a piece of 

brush glass or filters according to your need.
