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

IMPORTANT:METERSUSINGDRYAACELLS:USENON‐RECHARGEABLEALKALINEBATTERIESONLY.DONOT

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
T
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

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

Bookmarknotdefined..
2. Powerthemeterusingbatteriesortheincludedinternationalpoweradapter.
NOTE:connectingtheincludedUSBcabletoaportinacomputerwillnotsupplythe
appropriatepower.
3. TurnONthemeter.
4. IfthemeterhasaLCD(ESCM‐16andESCM‐17),waituntilthedisplaychangescolorsto
visuallyconfirmithasresetsuccessfullyafterconnectingittoaUSBportonacomputer.
ConnectingMeters
Thefirsttimethemeterisconnectedtoyourcomputer,the
operatingsystemwillinstallthenecessaryUSBdriversasshownin
Figure2.Thisprocesscouldtakeafewminutes.
Figure2:USBDriverInstallation.
SettingtheMeter
1. EnsurethedataloggingswitchisintheONposition.
2. ConnectthemetertothecomputerusingtheincludedUSBcable.
3. LaunchtheGasLab®software.
4. Connectthemeter/sensortoyourcomputer
NOTE:Themetermustbestartedatleast1minutepriortouseanddataloggingtoallowtheCO2
sensorenoughtimetowarm‐upandcalibrate.
Afterconnectingthemetertoacomputerandsettingit,theGasLab®softwarewillallowyouto
performthefollowingmainfunctions:
CollectReal‐time–databeingrecordedisdisplayedongraph.
ManageandDownloadLogs–provideoptionstomanagedatalogssavedinthemeter.

11
ConfigureSensor–provideoptionstosetupthesensorinsidethemeteranddatalogging
options,amongotherfeatures.
NOTE:AseparatedatafilewillbecreatedeachtimethemeterispoweredON(startslogging).
LoggingData
OncetheGasLab®softwarehasbeeninstalledandthemeterisconnectedtothecomputer,youcan
gatherdatainavarietyofways.Dependingonthetypeofmeter,datacanbecollectedinrealtime,
datalogscanbedownloadedfromthemeter’smemory(ifequipped),andsavedtothecomputer,
anddatacanbereviewedonthemeter’sLCDdisplay(ifequipped).
Foreachloggingsession
1. TurnthemeterON.
2. Themetermustbestartedatleast1minutepriortodeploymentanddataloggingtoallow
theCO2sensortimetowarm‐upandcalibrate.
3. Setthelogginginterval(min30sec)asdesiredandcommencelogging.
4. Whendataloggingiscompleted,turnthemeterOFF.
SettingtheLoggingInterval
Tochangethedefaultsettings,connectthemetertoacomputerusingtheincludedUSBcablethen
followtheprocedurebelow.
1. OpenGasLab®andselectdesiredmeter/sensorfromtheNOTE:RefertotheGasLab®
User’sManualformoreinformation.
2. PleasereferencetheincludedGasLab®manualfordetailedinstructiononusingthe
software.
NOTE:RefertotheGasLab®User’sManualforcompleteinstructions.
DisplayandAlarm(ESCM‐16,ESCM‐17only)
Thisdataloggingmeterincludesabuilt‐inaudible(80dB)alarmandanLCD(LiquidCrystal
Display)back‐litdisplaythatprovidesvisualindicationofthecurrentCO2levelbychangingcolor
togreen,yelloworred,dependingonCO2levelrangesselected.Thedisplaywillchangecolors
dependingontheactualCO2levelreadingsbysettingthe“Green”,“Yellow”,and“Red”ranges.
ThealarmissetperLEEDlevelsbydefaultbutcanbeprogrammedtootherstandardssuchas
OSHAlevelsusingtheGasLab®software.Thenewalarmlevelwillbemaintainedinthemeter’s
memory.
Duringoperation,whenthemeteristurnedon,andwhenthehighconcentrationCO2level
programmedisreached,an80dBalarmwillsound.Thealarmcanbemutedfor30secondsby
pressingthebuttononthefrontofthemeter.Thisfeaturecanbeprogrammedforuserpreference.
Calibration
TheCO2sensor,inIAQapplicationsonly,usesanalgorithmcalledAutomaticBackground
Calibration(ABC)toensuremaximumaccuracybycontinuouslyadjustingthezero‐point.
TheABCalgorithmallowstheCO2sensortodynamicallyshiftitsCO2readingbyaconstant.It
worksviastoringthelowestCO2sampletakenovertheABCPeriodandassumingthatthislow
valueisequaltoaknownvalue(thetargetvalue).ItthenadjuststheoutputoftheCO2readingby
thedeltabetweenthesevalues.Thisalgorithmdoesnotaffectthelinearizationoftheoutputsignal.
Forexample,bydefaultABCisenabledwithanABCPeriodof180hours,atargetvalueof400ppm,
andamaximumdeltaof30ppm.Thisoperatesundertheprinciplethatambient,outdoorairisat
400ppm.

12
ThesensorwillkeeptrackofthelowestCO2readingrecordedoveraperiodof180hoursandthen
adjustthezeropoint,upto30ppmatatime,towardsthatvalue.
Toensuremaximumaccuracyitisrecommendedtoinstallthedeviceinanenvironmentthatwill
routinelyseethislowvalue.
Inaddition,thismetercanbeexposedtofreshairforafewminutesbetweenusestoverify
calibrationbymakingsurethereadingsarecloseto400ppm,orcanbemanuallycalibratedusing
theGasLab®software.
