Adjusting the Brightness Balance of

Drawn Image and Specimen Image
1. While looking through the eyepiece, place a pencil, etc. on the drawing
paper surface.
2. Using the microscope's brightness adjustment knob @, adjust the bright-
ness until the tip of the pencil and the specimen can be seen clearly at the
same time.
}If the drawing paper surface is dark, drawing will be made easier by illumi-
nating the paper with an electric lamp.
}If the microscope's light preset button ² is set to the optimum brightness
position for drawing and if, when the light preset button is OFF, the bright-
ness is set to the darkest position, it will be possible to switch between the
image of the superimposed specimen and drawing and the drawing
image alone just by pressing the button.
Options
Using the 10X Drawing Lens (U-DAL10X)
}When the optional 10X drawing lens is used in place of the standard
drawing lens, the drawing field diameter can be expanded to 220 mm,
which means that the image can be projected to almost fill an A4-size
page.
