NOTE 

There are two adjustment screws for the mirror. Keep in mind that you might have to turn 

the other screw. Anyway you should turn the screws not more that ½ or ¾ turns. 

 

  Adjust the screws until the optical balance reaches a value of 0 ± 10 %%. 

 

Now the adjustment for the used solvent is finished.
