DOCTER NOBILEM 7 x 50 NAVIDOC - Manual (Page 11)

Eye error equalization
Models with centre adjustment:
• With the left eye look through the left binocular half and on the knob of the centre
adjustment (5) set the focus sharp on an object. Keep the right eye closed while
doing this.
• Then look through the binoculars with both eyes and at the right ocular change
the dioptric setting (6) until an equally sharp, circular picture is obtained.
Models with individual focussing:
• The eye error equalization occurs through adjusting the right and left ocular (7)
individually for each eye.
• When viewing, the right picture for the right eye as well as the left picture for the
left eye are individually adjusted at the right and left ocular.
• Adjust the settings of the oculars until you have an even sharp and circular
picture.
• Caution: The adjustments for right and left should be carried out by looking at
the same object in order to prevent incorrect settings.
Distance settings
Models with centre adjustment
• Different object distances require different binocular settings.
• During viewing the object the centre adjustment knob (5) is rotated to the right
and left until the sharpest and most contrasting view is achieved.
Models with individual focussing
• If the two oculars (7) are adjusted to the sharpest setting then there is no need
for further adjustment for viewing different distances.
• Only for viewing objects that are near to the maximum near point of the
binoculars will it be necessary to adjust the oculars in the + - direction.
Additional equipment variants and their application
The NOBILEM – Model 7x50 B/GA (IF) can be equipped optionally at the works with a
graticule plate for estimating distances of viewed objects.
Use with the graticule
If the binoculars is equipped with a graticule plate (on the right ocular side) then it is
possible to determine distances and sizes of objects. The estimation of distance with
the graticule plate is possible from a distance of 100 m.
