Focus Adjustment 

Adjusting the Rotation Tension of the  
Focus Adjustment Knob (Fig.8, Fig.9) 

To adjust tension, hold both left and right focus 
adjustment knobs

①

with both hands, hold the 

left knob (to prevent it from turning), and rotate 
the right knob clockwise to increase (tighten) or 
counterclockwise to decrease (loosen) the focus 
knob tension.  

After tension adjustment has been completed, 
always rotate both adjustment knobs in the 
same direction. 

Changing the Magnification 

The zooming knobs located on both sides of the 
zooming body will change the magnification of 
the specimen image. 

Total Magnification = Magnification of zoom 
body x magnification of eyepiece 
(i.e., 0.7 x 10=7x) 

NOTE:  If using the optional auxiliary 0.5x 
objective, then the above magnification would be 
multiplied by auxiliary objective magnification.   
(i.e., auxiliary 0.5 x 7=3.5x) 

FOR MICROSCOPES  
PURCHASED WITH ILLUMINATION

bottom).  

Brightness adjustment:  the right brightness 
adjustment knob

illumination, and the left brightness adjustment 
knob

④

Each knob has its own on/off. Rotate 
counterclockwise to increase the power and 
brightness.   Rotating clockwise would decrease 
the brightness until the power is off.
