tothecomputer,anddatacanbereviewedonthemeter’sLCDdisplay.
Foreachloggingsession
1. TurnthemeterONbyconnectingtopowersupply.
2. Themetermustbestartedatleast1minutepriortodeploymentand

Calibration
Allunitsareshippedfactory‐calibrated.Whenitistimetore‐calibrate,you
havetwochoices.YoucanshipyourSamplingDataLoggertousfor
recalibration,oryoucancalibrateityourself.
WhyisCalibrationrequired?
Overtimeallsensorsrequirerecalibration.Duringrecalibration,thesensoris
exposedtoaknowngassource,multiplereadingsaretaken,anaverageis
calculated,andthedifferencebetweenthenewreadingandtheoriginal
readingwhenthesensorwasoriginallycalibratedatthefactoryisstoredin
EPROMmemory.This“offset”valueisthenautomaticallyaddedorsubtracted
toanysubsequentreadingstakenbythesensorduringuse.
FactoryCalibration
Factorycalibrationisapre‐paidserviceCO2Meteroffers.Itnotonlycorrects
forsensordrift,butprovidesaCertificateofCalibration.ACertificateof
CalibrationisrequiredforproductsinISO9000,FDA‐regulated,government
contracted,orotherindustriesthatrequirestraceability.
Toorderfactorycalibration,youmustfirstgetaReturnMaterial
Authorization(RMA)number.Thisnumberinsuresweknowyourunitis
comingbacktoCO2Meterandreturnedtoyouthesamedayifpossible.To
obtainanRMAnumber,call(877)256‐4910M‐F9‐5pmESTorsendanemail
to:[email protected].Pleasehaveyouroriginalordernumberready.
YouwillreceiveanauthorizationcodetoaccesstheRMAsystem.
Onceyouhaveanauthorizationcode,gotohttp://rmasupport.net/rma2.aspx.
Fillintheform,entertheauthorizationcodeyouwereprovidedandanRMA
numberwillbeassignedtoyou.
Pleaseusetheoriginalpackaging(ifavailable)whenreturningthemeterto
CO2Meter.IncludetheprovidedRMAnumberontheoutsideofthebox,
preferablyontheshippinglabel.Securethemeterinsidethepackageproperly
topreventanydamageduringtransit.Shipthemetertotheaddresslistedon
yourRMApaperwork.

WhenwereceiveyourSamplingDataLogger,wewillrunadiagnostictest,
thencontactyouwithatotalcostforrecalibration,returnshipping,and
repair/replacement(ifrequired)ofanynon‐workingpartsrequiredto
completethecalibration.Oncecalibrationiscomplete,yourmeterwillbe
returnedwithaCertificateofRecalibration.
Allapplicableduties,tariffs,taxesandbrokeragefeesaretheresponsibilityof
thecustomer.
OrderingaFactoryCertificateofCalibrationduringPurchase
Insomecases,youmayneedanoriginalCertificateofCalibrationwhenyou
placeyourorder.Youcansavetimebyorderingyourcalibrationcertificateat
thesametimeyouplaceyourorder.
