USING THE CONTROLS

5-1 Base

5-2 Microscope Body and Focusing Assembly

Fig. 13

Using the Stage Plate

When reflected light is used, the stage plate is usually placed with the

white side facing up. In case the specimen is white or other bright colors,

place the stage plate with the black side up to improve contrast.

# When transmitted light is used, use the transparent glass stage

plate (SP-C).

Placing the Specimen

1. Place the specimen on the approximate center of the stage plate. Hold

the specimen with the specimen holder as required.

2. Illuminate the specimen with an illuminator selected according to the

specimen under observation.

Adjusting the Tension of the Coarse

Focus Adjustment Knob

# The tension of the coarse focus adjustment knob can be adjusted

with the tension adjustment ring @. Do not rotate the knobs on the

left and right in opposite directions, for this will damage the internal

mechanism.

1. Rotate the tension adjustment ring @ by inserting the Allen screwdriver

into the hole ² on the ring periphery.

Rotating the ring clockwise increases the tension of the coarse focus

adjustment knob, and rotating counterclockwise decreases it.

# If the microscope body falls down by its own weight or the focus

obtained by fine focusing is lost immediately, the tension adjust-

ment may be too light. In this case, rotate the ring clockwise to

increase the tension.

# If the tension adjustment is too tight, delicate focusing will be

impossible and the knob may be damaged. Particularly, never

rotate the fine focus adjustment knob quickly while its tension is

extremely tight.
