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.

Whenthemeterisleftpoweredon,aspecialcircuitisincludedinthismeterwhich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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.

Turn‐OnDiagnostics

1. WhenthemeteristurnedONtheLCDdisplays“SELF”and“CAL”whilethemeterrunsa

diagnosticroutine.

2. DuringthistimethemeterisrecallingtheUserCalibrationdata,performingselfdiagnostics

&initializingthecircuitry.

3. Afterthisfunctioniscomplete,themeterproceedstothenormal

measurementmode.

4. TheDO600shouldbecalibrateddailyformeasurementaccuracy.
