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 Rotation Tension of the

Coarse Focus Adjustment Knob

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

preventing the spontaneous drop of the microscope body. It is recom-

mended to set the knob rotation 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 rotation tension of the coarse focus adjustment knob can be

adjusted with the rotation 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 rotation tension adjustment ring @ by inserting the Allen screw-

driver ³ into the hole ² on the ring periphery.

Rotating the ring clockwise increases the rotation 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 rotation tension

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

increase the rotation tension.

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

be impossible and the knob may be damaged. Particularly, to pre-

vent damage, never rotate the fine focus adjustment knob quickly

while its rotation tension is extremely tight.
