1.  Adjust the eyetubes for your interpupillary 
distance.  Fold or unfold the eyetubes to 
decrease or increase the distance between 
the eyepieces until you see one illuminated 
circle. 
    
 
The viewing tubes maintain a constant 
tube length for all interpupillary settings. 
This means that a change of interpupillary 
distance does not affect parfocality, magnifica-
tion, or calibrations that depend on magnifica-
tion. 
Leica EZ Viewing Tube
If you are using a Leica EZ viewing tube, which 
already has the eyepieces integrated with 
the eyetubes, there are no additional adjust-
ments necessary. Be sure you are wearing your 
eyeglasses or contact lenses. Go on to section 
"Oil Immersion" on page 32.
Standard Viewing Tube with Two Fixed 
Eyepieces
If you are using a standard viewing tube with 
two fixed eyepieces (no focusing eyepieces), 
there are no additional adjustments neces-
sary. Be sure you are wearing your eyeglasses 
or contact lenses. Go on to section "Oil Immer-
sion
" on page 32.
