ImportantSafeguards

Toreducetheriskoffire,electricalshockand/orinjurytopersons,basicsafetyprecautionsshould

alwaysbefollowedwhenusingelectricalappliances,includingthefollowing:

1. READALLINSTRUCTIONSBEFOREUSINGTHISMETER.

2. INSTALLGasLab®SOFTWAREBEFORECONNECTINGMETERTOACOMPUTER.

3. Chargerechargeablemetersforatleast5‐8hoursbeforeuse.

4. Therechargeabledataloggerscontainalithiumpolymer(Li‐Ion)battery.Donotexposeto

extremeheatorcold.

5. TheLi‐Ionbatteryisnotuser‐replaceable.Pleasedonotattempttoopenthemeterand

replacethebattery.

6. DonotuserechargeableAAbatteries.

7. FormodelsusingAAbatteries,donotstorethemeterwiththeAAAlkalinebatteries

installedtopreventthepotentialforbatteryleakage.

8. Useonlythesupplied5/6VDCinternationalwallpowersupplyadapter.Precisely5/6V

mustbeappliedtothemeter.Othervoltagescancausepermanentdamage.

9. Themeterisnotdesignedforoutdooruse.

10. Donotallowthemetertobeexposedtowater.

11. Donotoperatethemeterwiththeenclosureopened.

12. Donotoperatethemeterifitismalfunctioning.

13. Useofthisdeviceinenvironmentsabove95%humiditymaycauseirreparabledamageto

thecomponents.

PoweringtheMeter

Alldataloggerscomewithaninternationalpoweradapterandtheyarealsobattery‐powered.

SomemetersarepoweredbyaninternalrechargeableLi‐Ionbatteryandothersbydrycellnon‐

rechargeablealkalineAAbatteries(notincluded),dependingonthemodelofthemeter.Thetable

belowshowsdetailedinformationaboutthebatteryusedbyeachavailablemodel.

Li‐IonBatteryLifevsLoggingInterval

Inoperation,theLi‐Ionpowereddataloggersdrawlessthan0.7mAcontinuouslyand~400mAfor

2.5secondsduringeachmeasurement.Eachhasaloggingcapacityof5,400time‐stamped

measurements.

7

Thisallowsusthefollowingcalculationtodeterminebothbatterylife(enduranceinthefield)and

thetimetofilltheloggingmemory:

AVERAGEDRAW(mA)=0.7(T‐2.5)+1,000

WhereT=themeasurementintervalinseconds.The.7(T‐2.5)givesusthecurrenttotalcurrentdraw

foronecycleofstandbybecausewedraw.7mAfortheentireintervalexceptthe2.5secondsofactual

measurement.Thenweaddthemeasurementcycleduringdrawof~400mAfor2.5s(2.5*400=

1,000).AndfinallywedividebyTtogettheoverallaveragedraw.

Forexample,theaveragedrawfora30secondinterval:

AVERAGEDRAW(mA)=0.7(30‐2.5)+1,000=33.9mA

30

TogettheEstimatedBatteryLife(EBL),wedividethebatterycapacitybytheaveragedraw.Inthe

caseofa2,200mAbattery,thiswouldbe:

ESTIMATEDBATTERYLIFE=2,200/33.9=64.9HOURS

TodeterminetheTimetoFillMemory(TTFM),weuseadifferentcalculation:

TTFM=SAMPLINGINTERVAL*5,400DATALOGS/3,600

Forexample,takingasampleevery30secondswouldmean:

TTFM =32*5,400/3,600

TTFM =48HOURS

Ofcourse,TTFMmustbelessthanEBL.Thismeansthatinmostcases,youcancompletelyfillthe

memorywithdatalogsmorethanoncebetweencharges.

BatteryLife

DataloggersusingAAdrycellalkalinebatteriescanruncontinuouslyforupto8hours,regardless

ofloggingintervalselected.

ThebatterylifefordataloggersusingarechargeableLi‐Ionbatterydependsontheselectedlogging

interval.Tablebelowshowstheestimatedbatterylife(EBL)andthetimetofilltheinternal

memory(TTF)basedonsometypicalloggingintervals.

Asshowninthetableabove,inordertocompletelyfilltheinternalmemoryatloggingintervals

equaltoapproximately670secondsorlonger,ahighcapacity(6,000mAh)Li‐Ionbatterywillbe

requiredifmeterisnotconnectedtopoweradapter,assumingmeterisfairlynewandbatterywas

IMPORTANT:DOWNLOADTHEDATALOGSREGULARLYTOPREVENTPOSSIBLEDATALOSS.ONCETHE

MEMORYISFULL,PREVIOUSLYLOGGEDDATAWILLBEOVERWRITTEN.

NOTE:TheAAbattery‐poweredMeter(ESCM‐18-CC)willhaveanestimatedbatterylifesimilarto

ProductOverview

Thisdataloggerisdesignedtomeasurecarbondioxide(CO2),percentofrelativehumidity(%RH),

andtemperaturethroughdiffusionsampling.Itstorescollecteddatatoitsinternalmemorytobe

retrievedatalatertimeforanalysis.WhencombinedwithourGasLab®software,youcanalsosee

real‐timedataonyourcomputer’sscreen.

Scientificdevicessuchasthisdataloggerrequiretheusertohaveanintimateknowledgeofthe

meter,itsoperation,therequiredsoftware,andthemeterspecificationspriortouse.Wehighly

recommendsreadingthisuser’smanualbeforeoperatingthedevice,especiallytheImportant
