4.4 Safety device
The fixing screw (P) locks the stand arm into its position. When loosening the fixing screw, one can
adjust the holder in height depending of the volume/height of the object. After adjustment the fixing
screw (P) should be tightened again and the safety device (O) repositioned and secured in order to
avoid that the arm stand can fall down unexpectedly !

The working distance (distance between front of objectives to top of object) is about 60 mm.

another magnification is set. Turn the nosepiece untill it clearly "clicks" into position.
