Interpupillary Distance Adjustment

# Be sure to hold the binocular assembly @ with both hands to make

this adjustment.

While looking through the eyepieces, hold the left and right of the bin-

ocular assembly @ and adjust the eyepieces by opening or closing

them for binocular vision until the left and right fields of view coincide

completely.

Diopter Adjustment

(Zoom Parfocal Adjustment)

# Ensure that the eyepiece clamping knob @ is tightened.

When not using the CROSS eyepiece

1. Rotate the diopter adjustment rings ² of the eyepiece so that both scales

indicate "0".

2. Place an easy-to-observe specimen on the stage plate.

3. Rotate the zooming knob ³ to a low magnification and focus the speci-

men using the coarse and fine focus adjustment knobs.

4. Rotate the zooming knob ³ to the highest magnification and focus the

specimen using the coarse and fine focus adjustment knobs.

5. Rotate the zooming knob ³ to the lowest magnification, then focus the

specimen by rotating the left and right diopter adjustment rings instead of

the coarse and fine focus adjustment knobs.

When using the CROSS eyepiece

1. Look into the CROSS eyepiece and focus the cross lines by rotating the

diopter adjustment rings.

2. Place an easy-to-observe specimen on the stage plate.

3. Rotate the zooming knob ³ to a low magnification and focus the speci-

men looking into the CROSS eyepiece and using the coarse and fine

focus adjustment knobs.

4. Rotate the zooming knob ³ to the highest magnification and focus the

specimen using the coarse and fine focus adjustment knobs.

5. Rotate the zooming knob ³ to the lowest magnification, then focus the

specimen by rotating only the diopter adjustment ring of the non-CROSS

side of the eyepiece instead of the coarse and fine focus adjustment

knobs.

}Note (or memorize) the diopter readings of the left and right eyepiece

scales so that they can be duplicated quickly in the next observation.
