8-2 The details of transmitted light brightfield
observation procedure
8-2-1 Set the main switch to "I"(ON) and adjust the
intensity of illumination.
A. Make sure that the light intensity control knob is in
the MIN(minimum intensity)position and set the main
switch to "I"(ON).
B. Rotate the knob toward MAX(maximum intensity)to
increase the intensity and the illumination brightness.
C. When the microscope system is not be used for a long
period,set the main switch to "O"(OFF).
8-2-2 Disengage the filter other than the frost filter
From the light path. (Please refer to 6-8.)
8-2-3 Select the light path with the light path
selector lever. The light path selector lever allows for
light path switching between the observation and side
port paths.
8-2-4 Place the specimen on the stage.
8-2-5 Engage a 10Xobjective in the light path.
8-2-6 Bring the specimen into focus.
(1) Rotation Direction of the Coarse/Fine Adjustment Knobs
Rotating the coarse or fine adjustment knob toward
the front(in the direction of the arrow) raises the objective
and toward the rear(opposite direction)lowers the objective.
(2) Adjusting the Coarse Adjustment Knob Tension
Always use the rotation tension adjustment ring to
control the rotation tension of the coarse adjustment knob.
The tension of coarse adjustment knob has been
pre-adjusted to optimum tension, but this can be changed as required. Turn the rotation tension
adjustment ring in the direction of the arrow to increase the knob's tension and in the opposite
direction to decrease it.
If the objective lowers by its own weight or the focusing obtained with the fine
adjustment knob is lost soon, the tension is set too low. In this case, turn the rotation tension
adjustment ring in the opposite direction to the arrow to increase the tension.
