Viewing Tube Adjustment

1.Adjust the eyetubes for your interpupillary distance. Fold or unfold the eyetubes to decrease or increase the distance between the eyepieces until you see one illuminated circle.

The viewing tubes maintain a constant tube length for all interpupillary settings.

This means that a change of interpupillary distance does not affect parfocality, magnifica- tion, or calibrations that depend on magnifica- tion.

Leica EZ Viewing Tube

If you are using a Leica EZ viewing tube, which already has the eyepieces integrated with the eyetubes, there are no additional adjust- ments necessary. Be sure you are wearing your eyeglasses or contact lenses. Go on to section "Oil Immersion" on page 32.

Standard Viewing Tube with Two Fixed Eyepieces

If you are using a standard viewing tube with two fixed eyepieces (no focusing eyepieces), there are no additional adjustments neces- sary. Be sure you are wearing your eyeglasses or contact lenses. Go on to section "Oil Immer- sion" on page 32.

Standard Tube with One or Two Focusing Eyepieces

If you are using a standard viewing tube with one or two focusing eyepieces, you need to make some adjustments:

1.Set the focusing eyepieces to the "0" diopter setting.
