3.0 UNPACKING AND ASSEMBLY
The microscope is located in a styrofoam moulded packaging. After removing the adhesive tape from
all packaging, lift the top half of the packaging. Pay attention not to drop or damage the optical com-
ponents(objectivesandeyepieces).Extractthemicroscopefromitspackagingwithbothhands(one
aroundthetoparmandonearoundthebase)andplaceitonastablesurface.Keepitawayfrom
solvents, chemical vapors and excessive moisture. Avoid high temperature environments, the direct
sunshineandexcessivevibrations,whichcouldaffecttheperformanceoftheinstrument.
3.1 Operating environment
Temperature: : 10 - 36°C (50 – 96.8°F)
Relative humidity: 0 – 85% up to 30°C (86°F)
3.2 Unpacking microscope
Control the packaging to ensure that all material is present. We recommend that you take note of all
the accessories to facilitate any future orders of spare parts and technical support calls. Make sure
that in the packaging no small accessories or small parts remain. Please keep the original packaging
in a safe place for future transport needs of microscope or accessories.
 Nevertouchtheglasssurfacessuchaslensesorlters.Tracesofgreaseorotherresiduescanredu-
cethevisionqualityofthenalimageandcorrodethesurfaceoflensesinashorttime.
3.3 Installing the microscope
 Settheopticalheadonthetoparmthroughthelockingscrew.Inserttheeyepiecesintothetubesand
lockthemwiththesmallscrewswhicharelocatedtothesideofthetubes.Removetheprotectivelm
from the stage of the microscope.
3.4 Connect the mains plug into the socket at the base

Page 8
Make sure, before you turn the illumination on, that the voltage selector is set to the mains voltage for
your region.
 Thepowercordshouldbeusedonlyonnetworksocketsequippedwithadequategrounding.
Contact a technician to check the state of your electrical system.
 Ifthereisnoneedtoinstalladditionalaccessories,theinstrumentisnowreadyforuse.
3.0 UNPACKING AND ASSEMBLY

Page 9
Oncepositionedandinstalledwiththenecessarycomponents,themicroscopeisreadytobeused.
Yourmicroscopeisalaboratoryinstrumentdesigned to last. Handle italwayscarefullyandavoid
abrupt vibrations or shocks.
Alwaysdisconnectthepowercablefromthemicroscopewhennotinuseforlongtime,whileyou
cleanitorwhenyouperformanymaintenance.
AVOID DISASSEMBLING THE INSTRUMENT
Donotdisassembletheinstrument.Thisentailsthecancellationofthewarrantyandmaycausemal-
function.
4.1 Observation head
 Loosenthelock-screw(1),turntheobservationheadtoacomfortablepositionforobservation,and
thenlockthelock-screw.
4.2 Place the specimen on the stage
Lock the specimen slide on the mechanical stage using the slide clamp. Ensure that the spe¬cimen is
centred over the stage opening by adjusting the coaxial knobs of the stage.
4.3 Illumination system settings
 ThemicroscopeisttedwithawhiteLEDilluminator.Beforeturningontheilluminationsystem,read
thesection5.3aboutelectricalsafetyprecautions.Inserttheplugofthecableintothepowersocket
andturnontheswitchonthebackofthemainbody.Turnthebrightnessadjustmentknobtoabright-
ness suitable for observation.
4.4 Adjust interpupillary distance
 Holdtherightandleftpartsoftheobservationheadwithbothhandsandadjusttheinterpupil¬lary
distancebyturningthetwopartsuntilonecircleoflightcanbeseen.
 Thewhitedot(°)placedontherighteyepieceshowsthesetinterpupillarydistance.Justremember
this value to help on later settings.
4.5 Focus tension adjustment
The tension of the coarse focusing knob is preset by factory. To change the tension according to your
preference,justrotatetheknob(5)clockwiseinordertoincreaseit.
Excessive tension could damage the mechanism of focus. A too loosed tension causes the descent
of the stage by gravity or a sudden loss of focus. In this case, rotate the knob (5) to increase the ten-
sion.

4.6 Diopter adjustment
Turnthedioptricadjustmentringontherighteyepiecedioptricuptoalignthebottomwiththegradua-
tedring.Turnthecoarsefocusknobinordertofocustheslidewithanobjectivewithlowmagnica-
tion.Adjustthenefocusknobuntilyouobtainaclearanddenedpictureobservingwiththeright
eye,andthenrepeattheoperationwiththeleftdioptriccompensationringandthelefteye.Whenthe
imageappearsinfocus,choosethenecessaryobjectivewiththerevolvingnosepiece.
4.7 Condenser
Raiseorlowerthecondenserthroughtheknob(4)toobtainaclearanduniformilluminationofthe
sample.
Tocenterthecondenser:completelyclosetheirisdiaphragm(3).Usingthecondensercenteringscrews
(2),movethediaphragminthecenteroftheeldofview.Thengraduallyexpandthediaphragmuntil
itistangenttotheedgesoftheeldofview.Ifnecessary,youcanperformanadditionaladjustment.
Thecondenseriscenteredwhentheedgesofirisdiaphragmaretangenttotheeldofview.
4.8 Numerical aperture setting
The value of the numerical aperture (N.A.) of the diaphragm is an indication of the contrast of the illu-
minationsystem.Matchingthevalueofilluminationsystem’sN.A.withthatoftheobjectiveensures
the best results in terms of contrast and image quality. To set the numerical aperture of the Illuminator,
adjusttheopeningoftheirisdiaphragm(3).Inthiswayyoucontrolcontrastandimageresolution.For
sampleswithlowcontrastsettheiristoabout75%ofthevalueoftheobjective’snumericalapertu-
re.
4.9 Phase rings centering (models B-352Ph and B353Ph)
Formodelsequippedwithphasecontrastset,youhavetoperformthecenteringofthephaserings.
Remove an eyepiece from the head and insert the centering telescope in the empty tube.
