Assembling Steps
2-2-1
Assemble the Koehler Illuminator
Condenser
(1) Rotate the coarse focusing knob
①
to raise
the stage to the highest position (see Fig. 4).
(2) Rotate the condenser up-down knob
②
to
lower the bracket of condenser to the suitable
position.
(3) Fully loosen the condenser lock-screw
③
.
(4) Align the orientation screw at the back of
condenser with the groove of condenser base,
and push the condenser to the innermost of the
condenser base.
(5) Tighten the lock-screw
③
of condenser, then
raise the condenser with the up-down knob
②
to
the highest position.
2-2-2
Assemble the Objective
1. Rotate the coarse focusing knob
①
to lower
the stage to a suitable position (see Fig. 5).
2. When installing the objectives, install the 4X,
10X, 20X, 40X, 100X objective matching with
the nosepiece hole 1, 2, 3, 4, 5 (see Fig. 6).
★
When operating, first use the low
magnification objective (4X or 10X) to search
for specimen and focus, and then replace with
high magnification objective to observe.
★
When replacing the objective, rotate the
objective nosepiece until it sounds “ka-da”, to
make sure the objective wanted is in the
center of optical path.
3. The objective nosepiece has memory function,
which can automatically memorize the brightness
value saved by the objectives of each
magnification.
When the nosepiece is rotated clockwise or
counterclockwise but does not enter the next
objective position, the brightness value and
magnification display remain unchanged. After
entering the new objective magnification position,
the brightness value is displayed as the value
previously saved by the magnification objective,
and the objective magnification display is
updated to the current objective magnification.
