Introduction



ThankyouforselectingtheExtechInstrumentsModelCO240.TheCO240measuresCarbon

Dioxide(CO2),AirTemperature,andRelativeHumidity.ItalsocalculatesDewPointTemperature

andWetBulbTemperature.Theuser‐programmablehighalarmfeaturealertstheuserwhen

CO2levelrisesabovetheprogrammedlimitandthedatastreamingfeatureallowsreadingstobe

capturedinrealtimebyPC(USBconnection).Thisdeviceisshippedfullytestedandcalibrated

and,withproperuse,willprovideyearsofreliableservice.Pleasevisitourwebsite

(www.extech.com)tocheckforthelatestversionofthisUserGuide,ProductUpdates,and

CustomerSupport.

Operation

Poweringthemeter

MomentarilypressthePOWERbuttontopoweronthemeter.HoldthePOWERbuttonfor2

secondstoturnoffthemeter.Duringmeasurement,ifthealarmissounding(audiblebeeper)

pressthePOWERbuttonmomentarilytoturnoffthebeeper.Pressagaintoactivatethebeeper

function.ThealarmbeeperissettoONbydefault.Themetercanbepoweredby6AAA

batteriesorACAdaptor.

Recommendation:Fordatalogging,powertheunitusinganAC/DCadaptorinordertoconserve

batterypower.

AutoPowerOff

TheCO240willautomaticallyturnoffafter20minutesofinactivity.Todisabletheautopower

offfunction:WiththemeterOFF,pressandholdtheHOLDbuttonandthenpressthePOWER

button.TheLCDwillshow“n”,andwillthenreturntonormalmeasurementmode.

Measurements

Whenthemeteristurnedon,aself‐testisimplemented.DuetothenatureoftheNDIRsensor,

ittypicallyrequiresapproximatelytenminutestoobtainstable,accuratereadings.IftheUSB

cableisconnectedtotheCO240,theUSBsymbolwillbeshownontheLCD.

ThetemperatureandrelativehumidityreadingswillalternateonthelowerLCDlinealongwith

theCO2readingonthetopdisplayline.UsetheMODEbuttontoswitchtoDP(DewPoint

Temperature)andWB(WetBulbTemperature)modes(lowerdisplayline).

MaximumandMinimumReadingsMemory

MomentarilypresstheMAX/MINbuttontoreviewthemaximumandminimumreadings

capturedsincethemeterwaspoweredon.Pressingthebuttononcewillshowthemaximum

value.Pressingthebuttonagainwilldisplaytheminimumvalue.Pressingthebuttonathirdtime

willreturnthemetertoitsnormalmodeofoperation.WhileinMAX‐MINmode,pressandhold

theHOLDbuttonfor2secondstoreset(clear)thestoredmaximumandminimumvalues.

SelectingoC/oFunitsofmeasure

PresstheUNITbuttontoselectthedesiredtemperatureunitofmeasure.

Calibration

PressandholdtheSET+UNITbuttonsfor2secondstoentertheself‐calibrationmode.Ensure

thatthereisaslittleCO2presentaspossible.Itisrecommendedthatthisbedoneinoutsideair.

TheLCDwilldisplay“CAL”andwillperforma60‐secondcountdownasitperformsthe

calibration.Areadingof“400”isdisplayedasanormalCO2levelreferencevalueduringthe

calibration.Afterthecalibrationhascompleted,themeterwillreturntoitsnormalmode

operation.

AutomaticCO2BaselineCalibration(ABC)

TheABCalgorithmcontinuallytracksthesensor’slowestreadingoverafixedtimeintervaland

slowlycorrectsforanylong‐termdrift(ascomparedtotheexpectedfreshairvalueof400ppm).

TheABCperiodis15days,duringwhichtheABCfunctiondefaultisalwayson.

CO2AlarmSetting

PressandholdtheSETbuttonfor2secondstoenterthehighCO2alarmthreshold.Pressthe

HOLDbuttontoincreasethevalue,andtheDownarrowbuttontodecreasethevalue.Pressthe

MODEbuttontoselectthedigittotheleftandpresstheMAX/MINbuttontoselectthedigitto

theright.Oncethedesiredvalueisset,presstheSETbuttonfor2secondstosavethealarm

setting.TheLCDwillreturntoitsnormalmodeofoperation.Themeteralarmlimitdefaultis

1000ppm(OSHA).MomentarilypressthePOWERbuttontotogglethealarmonandoff.

DataStreamingtoPC

TheCO240featuresreal‐timedatastreamingtoaPCusingthesuppliedSW200‐Ssoftware.

WhenthemeterisconnectedtoaPC,theUSBiconwillbevisibleontheLCDdisplay.Please

installtheUSBdriverandsuppliedsoftwarebeforeattemptingtostreamdata.RefertotheHelp
