Interpupillary Distance; Focusing; Illumination - Accu-Scope EXI-310 Series Manual

EXI-310 INVERTED MICROSCOPE SERIES
OPERATION
Plug the 3-prong line cord into the microscope and then into a grounded 120V or 220V A.C. electrical outlet.
Usage of a surge suppressor outlet is highly recommended. Turn the illuminator switch ① to "―" (Fig. 6) For
longer bulb life always turn the illuminator variable intensity knob ② to the lowest illumination intensity setting
possible before turning the power on or off.
Adjusting the Illumination (Fig. 5)
The light level may need adjustment depending upon the
specimen density and objective magnification. Adjust the
light intensity for comfortable viewing by turning the light
intensity control knob clockwise to increase brightness.
Turn counterclockwise to decrease brightness.

Adjusting Interpupillary Distance (Fig. 6 & 7)
To adjust the interpupillary distance, hold the left and right
eyetubes while observing a specimen. Rotate the eyetubes
around the central axis until the fields of view of both eyetubes
coincide completely. A complete circle should be seen in the
viewing field when viewing the specimen slide. An improper
adjustment will cause operator fatigue and will disrupt the
objective parfocality.
Where the "●" ① on the eyepiece tube lines up, that is the
number for your interpupillary distance. The range is 54-75mm.
Be sure to write down you interpupillary number for future
operation.

Adjusting the Focus (Fig. 7)
①
To ensure that you obtain sharp images with both eyes, (since
eyes vary, especially for those wearing glasses) any eyesight
variation can be corrected in the following manner. Set both
diopter collars ② to "0". Using your left eye only and the 10X
objective, focus your specimen by adjusting the coarse
adjustment knob. When the image is in view, refine the image
to its sharpest focus by turning the fine adjustment knob.
Rotate the diopter collar to obtain the sharpest focus. To obtain
the same sharp image using your right eye, do not touch the
coarse or fine adjustments. Instead, rotate the right diopter
collar until the sharpest image appears. Repeat several times

to check.
IMPORTANT: do not counter rotate the focusing knobs as this will
cause severe problems and damage to the focusing system.
