Operation
PreparetheElectrode
Theelectrodeisshipped“dry”andrequiresfillingwiththesuppliedelectrolytesolutionbefore
use.Themembraneshouldbeinplaceanddoesnotneedreplacement.Followtheprocedureat
theendofthisguideforfillingthebondedcap.
NOTE:Makesurethattherearenoairbubblesintheelectrodebeforeuse.
PoweringtheExStik®
TheExStik®usesfour(4)CR2032LithiumIonBatteries.PresstheON/OFFbuttontoturnthe
meteronoroff.Ifthebatteriesareweak,the‘BAT’indicatorappearsontheLCD.Theauto
powerofffeatureshutstheExStik®offautomaticallyafterapproximately10minutesof
inactivity.Theautopowerofffeaturemaybetemporarilydisabledforconvenienceorfor
extendedpolarizationtime.
StartupPolarizationPeriod
WhentheExStik®ispoweredupforthefirsttime,theelectroderequirespolarization.Inorder
forthistooccurathreeminute(approx.)polarizationperiodmustelapsebeforemeasurements
canbemade.Aspecialcircuitisincludedinthismeterwhich,uponturn‐on,maintainsavery
smallbiasingcurrenttotheelectrodeforaperiodofsevendays.Thiskeepstheelectrode
polarizedandenablestheusertomakeimmediatemeasurements(withina7dayperiod)
withoutwaitingfortheelectrodetore‐polarize.EachtimetheExStik®isturnedon,the
polarizationtimerisresetandthe7daypolarizationperiodisinitiated.Asmallasteriskatthe
bottomrightcornerofthedisplayisusedtoindicatethatthepolarizationtimercircuitisactive
evenwhenthemeterisoff.IftheExStikisnotusedformorethansevenday,a3minutewaiting
periodisrequiredbeforeameasurementcanbemade.

MeasurementandDisplayConsiderations
TheDO600usesapolarographicsensor,whichconsumesoxygenatthesensingsurface.
Thisrequiresaconstantmovementofthesampleacrossthemembranetomaintaina
constantdissolvedoxygenlevel.Itisrecommendedthattheprobebemovedinthesample
asthemeasurementismade,orifinalaboratoryenvironment,thesamplebestirredusing
astirplate.
IfyouaremeasuringDOinasmallcontainer,theprobewillconsumeoxygenasitis
measuringandthemeasurementvaluewillcontinuetogolower.
Iftheunitappearstobelocked(displayfrozen).ItispossiblethattheDataHoldmodehas
beeninadvertentlyaccessedbyapressoftheMODE/HOLDbutton(HOLDwillbedisplayed
inthebottomleftoftheLCD).SimplypresstheMODE/HOLDbuttonagainorturnthe
meteroffandbackonagain.
Ifthemeterdoeslatchupandnobuttonpressesreviveit,removethebatteriesandrestart.
Formaximumaccuracy,allowsufficienttimeforthetemperatureoftheprobetoreachthe
temperatureofthesamplebeforetakingareading.Thiswillbeindicatedbyastable
temperaturereadingonthedisplay.

DOBondedMembraneCapreplacement
ImportantNote:Donottouchthemembraneasskinoilswillinterferewiththeoxygen
permeabilityrateofthemembrane.Usecautionwhenreplacingthebondedcap.
1. Itisrecommendedthattheelectroderemainattachedtothemeterduringthis
replacementprocess.
2. Toremovethebondedcapfromtheelectrode,unscrewthecapfirmlyandcarefully
counter‐clockwisefromtheelectrode(seediagrambelow).
3. Discardtheusedcap.PleaseNote:Theinstallationofabondedcapcausesthemembrane
tobetightlystrechedoverthecathode.Onceabondedcapisremovedreinstallationisnot
possibleasthemembranewillnolongerbeproperlystrechedoverthecathode.
4. RinsetheoldelectrolytesolutionfromtheCathodeandAnodebeforecontinuing.
5. UsethesuppliedPolishingPaper(SeeAccessoriestable)toclean,polish,shine,and/or
removescratchesfromthecathode.Besuretomoistentheclothbeforepolishingthe
cathode.Donotover‐polishthesensitivegoldcathode.
6. Setthenewreplacementbondedcaponaflatsurface.Leavethecapinthisposition
throughoutthereplacementprocess.
7. Fillthebondedcapwiththeelectrolytesolutionuptothebottomofthethreadsonthe
insideofthecap.
8. Tapthesideofthebondedcaptohelpjarfreeanytrappedairbubblesfromtheelectrolyte
solution.
9. Keepingthecapinafixedpositiononaflatsurface,carefullyinserttheelectrodeintothe
newbondedcapbyfirstdippingandremovingtheelectrodeseveraltimesfromthecap.
Witheachdip,pushtheelectrodeprogressivelydeeperintothebondedcap.Finally,screw
theelectrodeslowlyontothebondedcap(clockwise)untilfullytightened.Thedippingand
removaltechniqueminimizestheintroductionofairbubblesintotheelectrolytesolution.
Airbubblesintheelectrolytecancompromisemeasurements.
10. Duringthetighteningofthebondedcap,excesselectrolytesolutionwillleakout,thisis
normalanddesireablesinceitminimizestheintroductionofairpockets.Cleanoffthe
