by left eye and turn coarse
focusing knob to find the image,
then turn slowly fine focusing
knob to make the image clear. Fig.3
After that,put high power objective into the optical path.
3.2.4. Pupil Distance Adjustment and Diopter Adjustment
3.2.4.1 Interpupillary Distance Adjustment (As shown in Fig.3)
Interpupillary distance is different for everyone, so it is necessary to adjust
interpupillary distance before using binocular microscope. Please take the two
eyepiece tubes and turn until the rings observed by two eyes are in superposition
entirely.
3.2.4.2 Diopter Adjustment (As shown in Fig.3)
