SOLUTION
-Check that there is a good power cord connection...
-Check that the fuse and the lamp are in good state.
- Check that when you revolve the nosepiece the objective is
centered in the optical path correctly.
-Check the correct centering of condenser. This will be done
with three small screws located round the condenser harness.
- Check dirt or dust on the lens ( pre-condenser eyepiece, field
lens.) Once the problem is located,clean the sample.
-Check the friction ring tension, it may be too weak and crea-
tes an involuntary fall down of the slide.
- Check the objective is correctly located in the optical path. If
not, revolve to clic-stop position..Check the sample is correctly
located-in the slide, make sure it´s firmly held by the clip.
- Check if the slide is upsidedown (the microsope slide is over
the coverglass). Proceed to the correct position if necessary.
The coverglass has a specific thickness (0.17)
-Check that focus control device is not on. If it´s on, it won´t
let move macrometrical adjustment as needded.
