OPERATION

Fig. 4

Positioning the Drawing Paper

Place drawing paper horizontally on the desktop exactly below the mirror

in the mirror housing. The paper should be secured after alignment.

Adjusting the Mirror Housing

1. Loosen the mirror housing clamping knob @ and rotate the mirror hous-

ing until it is positioned perpendicularly to the drawing paper.

2. Clamp the mirror tube by tightening the clamping knob @.

Focusing on the Specimen

Operate the coarse and fine adjustment knobs on the microscope to

focus on the specimen.

Removing the Light Excluding Cap

When drawing, detach the light excluding cap ² from the mirror tube

bottom.

Focusing the Drawing Paper

Rotate the focusing collar ³ on the drawing attachment to focus on the

drawing paper.

Determining the Drawing Projection Magnification

1. Place an objective micrometer on the stage and a scale on the drawing

paper surface. While looking through the eyepiece, find the place where

the objective micrometer graduations and scale graduations match pre-

cisely.

Drawing projection magnification =

# Match the units.

2. When an objective micrometer is not available, place a scale on the draw-

ing paper as in step 1 and read the diameter of the drawing field.

Drawing projection magnification =

Drawing field diameter (mm)

Eyepiece field number

The specimen sketch drawn on the paper will conform to this magni-

fication.

}After using either of the methods described in steps 1 and 2 to find the

drawing projection magnification, it is recommended to draw a scale on

the drawing paper so that the specimen size can always be determined

with ease. If an objective micrometer is available, drawing its scale on the

paper will further simplify the procedure.
