3. Observation

Placethedesiredobjectinthemiddleofthestage(10)andsecureitwiththeclamps(11)if

necessary.Theobjective’smagnication(1x,2xor4x)canbeadjustedbyturningtheobjective

holder(12).Itisrecommendedtostartobservationsalwayswiththelowestmagnication

(1x).Nowlookthroughtheeyepieces(1)atthebinocularhead(3).Adjustthesharpnesswith

thefocuser(4).

4. Focusing and dioptre compensation

Setthedioptrescale(2)totothemiddleposition(shinyring)andobserveanobject.Now

closeyourlefteyeandadjustthefocuswiththefocuser(4)foryourrighteye.Then,closeyour

righteyeandadjustthefocusforyourlefteyewiththedioptrescale.Now,themicroscopeis

adjustedforyoureyes.Notethesettingofthedioptrescaleyouneedtouseinfuture.

5. Eye distance

TheAnalythSTRisequippedwithanadjustablebinocularhead.Tosetyoureyedistance,

movetheeyepiecesagainsteachotheruntilyoufoundtheidealposition.

6. Replacing the Eyepieces (optional)

TheLEDilluminationhasalifespanofapprox.20,000hours.Inthecaseofatechnicalerror

pleasecontacttheservicecenter.

7. Adjusting the friction of the focusing drive

ItcanhappenthattheMicroscopeheadisnolongerheldbythefocusingdriveandshuts

downbecauseofhisnetweight.

Byturningthetwofocusingwheelsinoppositedirections,thefrictioncanbeadjustedmore

rmlyorloosely.

8. Cleaning and maintenance

Yourmicroscopeisahigh-qualityopticalinstrument.Pleasetakecarethatneitherdustnor

ngerprintstakeplaceontheopticalsurfaces.Ifnecessary,cleanthemicroscopebodywitha

slightlymoistenedsoftcloth.Useaseparatecleanclothwithsomedropsofalcoholtoclean

theopticalsurfaces.Afterusing,themicroscopeshouldbeprotectedwithitsdustcover.

Note:

Pleaseconsiderthatasufcienttreatedmicroscopekeepsitsvalueandopticalqualityfor
