steps
The lighting switch is located on the microscope cable.
1. Turn on the main switch (22).
2. The angle of the lighting can be set using the adjustment knob (14) which can be used
to change the lens direction.
B. Setting the eye viewing distance
1. Look through the eyepiece (1) and move the eyepiece tubes (3) by holding the prisma
casing (4) tightly and moving it to the left or the right.
2. The eye distance is correct once the field of view can be completely seen through
both eyepieces and both views combine into one field of view.
3. The eye viewing distance should be adjusted individually for each user.
C. Focussing
1. Use the zoom button (11) to set the lowest enlargement setting (1x).
2. Place a flat object in the middle of the welding table (8).
3. Turn the focus knob (15) to a middle focus range.
4. The attachment support (17), located on the tripod column (19), can be moved up or
down depending on the size of the object of focus.
a. Hold the attachment support (17) with one hand without touching a lens and
loosen the knob (16) on the attachment support (17) with the other hand. The
attachment support can now be moved all the way down to the base (9).

downwards until the object comes into focus.

release the attachment yet.
