2.UNPACKINGANDASSEMBLINGTHEMICROSCOPE
2.1 Unpacking the IVIicroscope
The componentsforSMZ-171stereomicroscopesareshippeddetachedforprotection.Openthe
styrofoampacking
with careanddonotleaveanycomponentsattachedtothepackingbeingremoved.
Do notdiscardanyofthepackingmaterials until allofthecomponentshavebeenidentified.Ifany
damage occursduringtransit,contactboththecarrierandyoursupplierimmediately.
2.2AssemblingtheMicroscope
2.2.1Whenhandlingthecomponents,especiallytheopticalparts,avoidtouchinganylenssurfaces

2.2.2Afterunpackingthestand,putitona stableand flat table.Loosenthelockingscrewofthe
head holder,adjusttheheightoftheheadholderandlockthelockingscrewagain.Make
sure that thesupportcollarissecured firmly belowtheheadholderalongtheverticalpost.

2.2.4Putthestereobodyontotheheadholderandlockitusingthelockingscrewlocatedonthe
right handsideoftheheadholder.Tomaintainthebeststability,youareadvisedtolockthe
screw onthe left handsideoftheheadholderaswell.

putting intheeyepieces.
2.2.6Beforeturningonthepower,plugtheilluminationpowercord into thesocketatthetopofthe
column. Next,plugthepowercordofthemainframe into thelocalpowersupply. Note: before
plugging in and turning onthe power, make sure that the operation voltage ofthe
microscope matches the voltage ofthelocal power supply.

light bulb,makesure that thepowerisswitchedoffandthepowercordhas
been disconnected from themainpowersupply.

4.1 Stereo Body with Binocularor Trinocular Head
For theSMZ-171stereomicroscopes,thebinocularortrinoculartubesare built into thestereobodyto
forma single unit calleda "Stereo-head". TheSMZ-171BL(Fig.1)isequipped with a binoculartube
whiletheSMZ-171TL(Fig.2)isequipped with a trinoculartube.
