OPERATION 

 

 

 

 

 

 

 

 

 

 

 

Setting Illumination For LED Models (Fig. 1) 

Turn the light adjustment knobs 

 and 

 as shown on 

the base in Fig. 3:  turn clockwise to increase 
brightness; counterclockwise to decrease brightness. 

 
 

Using the Black & White Stage Plate (Fig. 2 ) 

For instruments supplied with a Plain Focusing Stand 
or Pole Stand, the user can use either side of the Black 
& White Stage Plate.  For samples that are white or 
other bright colors, the black surface is typically facing 
up to help increase contrast of the image. For other 
darker colored samples, the white surface is 
recommended. 
 
To remove the plate or reverse it, press down on the 
supporting point (Fig 2) so the other side of the plate 
lifts up for removal/reversing. 

 
 

Adjusting the Rotation Tension of the  
Focus Adjustment Knob (Fig. 3) 

To adjust tension, hold

 

both left and right focus 

adjustment knobs

 

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 

 
 

Adjusting Diopter Ring (Fig. 4) 

 

Set the diopter rings

 

of both eyepieces to “0” position. 

(Do this when users change, because different users 
will have different diopter settings.) 

Place an easy-to-observe specimen on the stage plate. 

Rotate the zoom knob

 

to the highest magnification, 

then turn the focusing knob

 

to focus the specimen.

  

Rotate the zoom knob

 

to the lowest magnification, 

looking only into the left eyepiece, adjust the diopter 
ring on left eyepiece to focus the specimen. Then 
repeat procedure for the right eyepiece.
