Troubles Causes 

Corrective 

Measures 

Revolving nosepiece not in 
click-stop position (objective not 
centered in the optical path). 

Revolve to click-stop position 
(swing the objective correctly 
into the optical path). 

Condenser position too low. 

Position the condenser slightly 
lower than the upper limit.   
(P. 38) 

Condenser not installed 
correctly. 

Install correctly. (P. 38)

correctly. 

Install correctly. (P. 40) 

Lamp not installed correctly. 

Install correctly. (P. 39) 

Dirt or dust on the lens 
(condenser, objective, field lens, 
eyepiece, specimen) 

Clean the lens. (P. 49) 

Optical path selection lever on 
the trinocular eyepiece tube is 
not in click position. 

Optical path selection lever on 
the trinocular eyepiece tube is 
not set for 100% binocular part. 

Set the lever correctly for 100% 
binocular part. 

Filter is out of position. 

Set correctly on the field lens. 

The top lens of the swing-out 
condenser is not set in correct 
position. 

Swing in or out till the limit. 

Bertland lens in the optical path. 

Remove it. 

P-CL, P-CS or P-CQ sliders not 
set correctly.
