Introduction

CongratulationsonyourpurchaseoftheModelCO220CarbonDioxideMeter.Thismeter

measuresCO2concentration,airtemperature,andrelativehumidity.TheCO200includesa99

MemoryDataloggerforstoringandretrievingreadingswithdateandtimestamping.

Theaudiblealarmsmakethisisanidealinstrumentforindoorairquality(IAQ)diagnostics.

Carbondioxide(CO2)isagaseouscomponentoftheearth’satmosphere.Theconcentrationof

CO2innaturalambientairisapproximately0.04%or400ppm.

Thismeterisshippedfullytestedandcalibratedand,withproperuse,willprovideyearsof

reliableservice.Pleasevisitourwebsite tocheckforthelatestversionofthisUserGuide,

ProductUpdates,andCustomerSupport.

FEATURES

ExtraLargeLCDsimultaneouslydisplaysCO2Level,AirTemperature,&RelativeHumidity

DisplayedCalendarClock.

Six(6)iconsindicateindoorairqualitylevels(350/450/700/1000/1250/5000ppm)

StableNDIRsensorforCO2detection

AutomaticBaselineCalibration(ABC)function

AudiblehighCO2concentrationalarmwithselectablehighalarmthreshold

Operation

POWERINGTHEINSTRUMENT

PowertheunitbypluggingtheACadaptorintothemeterand

intoanACsource.ThemeterwillswitchONwithashortbeep.

Pleaseuseanappropriatepowersource:100to240VAC(50‐60Hz).

TheACadaptor’soutputvoltageis7.5to9.0Vanditsoutput

currentis0.5A.Useof3rdpartyACadaptorcandamagethemeter.

TheLCDwilldisplaythecurrentCO2

concentration

,airtemperature,

relativehumidity,date,andtime(dateandtimetoggleevery10

seconds).Sixfacialiconsindicatetheindoorairqualityleveland

appearonthetop‐tierdisplayarea(seefigureatrightandthe

sectiontitledDisplaySymbolsearlierinthisguideforadditional

details).

CO2MEASUREMENTCONSIDERATIONS

ThemeterstartsmeasuringwhenpoweredONandupdatesreadingsevery6seconds.

Responsetimeis10secondsforCO2and2secondsforRelativeHumidity.

Iftheenvironmentalconditionschange(forexample,alowtohightemperatureswing)please

allow30secondsforCO2readingsand30minutesforRelativeHumidityreadingstostabilize.

NOTE:DonotholdthemeterclosetothemouthoranyothersourceofCO2.

CHANGETHETEMPERATUREUNITS(oC/oF)

Thechangethedisplayedtemperatureunitsofmeasure:

1. PressandholdtheSETbutton

2. WhileholdingtheSETbutton,presstheoC/oFbutton

3. Repeatthesestepstochangetheunitsagain

VENT.R(CO2‐baseddemand‐controlledventilation)

CO2‐baseddemand‐controlledventilationreferstothepracticeofusingcarbondioxide

concentrationsasanindicatorforaper‐personventilationrate.Inthiscontext,CO2ismonitored

asabyproductofrespirationratherthanasanindoorcontaminant.Therateatwhichpeople

produceCO2varieswithdietandhealth,aswellaswiththedurationandintensityofphysical

activity.Themoreexertionanactivityentails,themorecarbondioxideisproduced.

CHANGINGTHE2NDTIERDISPLAYCOMBINATION

RepeatedpressesoftheC/F‐RH%buttonstepthroughthefollowingcombinationsof

parameters:

Humidity+AirTemperature

Humidity+WebBulbTemperature

Humidity+DewPointTemperature

MAX/MINMEMORY

ThemeterautomaticallyrecordsMaximumandMinimumreadingswhenthemeterisswitched

ON.Inthenormalmode,presstheCO2buttontoseethemaximumandminimumlevelsofCO2.

WhileviewingtheMaxorMinreading,pressandholdtheSELECT/RECALLbuttontoresetthe

MAXorMINmemory.The“Clr”iconwillappearfor2secondsandthedisplaywillbegintracking

newMAXandMINreadings.

DATALOGGERMEMORY99READINGS

Theusercanstoreupto99CO2readingsinmemoryforlaterrecall.

PresstheESC‐MEMbuttonmomentarilytosavethecurrentCO2

thememorylocationnumberwillreplacetheRHreadingfor2

secondsbeforereturningtotheRHreading.

Oncethememoryisfull,themeterwilloverwritethefirstdatapoint

storedandcontinuetooverwriteexistingreadingsasnewreadings

arestored.

TorecallthedatausetheSELECT/RECALLbutton.Themiddletierdisplaywillshowthe

memorylocationnumberandthetoptierdisplaywillshowthestoredreadinginppm.The

bottomtierdisplayshowsthedate/timestampforthedisplayedreading.
