USING THE CONTROLS

4-1 Base

4-2 Microscope Body and Focusing Assembly

Fig. 4

Using the Stage Plate

In reflected light observation, the stage plate can be placed either the

white or black side facing up.

# Win transmitted light observation, 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

}This operation is intended to facilitate the rotation of the knobs while

preventing the spontaneous drop of the microscope body. It is

recommended to set the knob tension to a slightly higher level than the

point where spontaneous drop occurs.

If the knobs are hard to move because of the weight of option modules

and/or TV camera mounted on the microscope body, it is recommended

to use the focusing assembly for heavy load (SZX2-FOFH).

# 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

³ 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 adjustment

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, to prevent

damage, never rotate the fine focus adjustment knob quickly while

its tension is extremely tight.
