Operating

Diopter adjustment If you adjust the diopters at the adjustable eyepiece as and setting described below, the focus will remain constant, or par- parfocality focal, from minimum to maximum magnification. In other

words, you will not have to refocus when you change magnification, but only when you want to examine a higher- or lower-positioned object segment. Make full use of this feature, which is not available on every stereo microscope.

Diopter adjustment is possible within a range from +5 to –5.

Every user has to make the following adjustments only once.

If you are using a graticule, the diopter adjustment and parfocality setting procedure is slightly different to that described here. Please refer to the section on measure- ment in the graticule user manuals.
