Introduction

ThankyouforselectingtheExtechInstrumentsModelCO40.TheCO40simultaneouslymeasures
COconcentrationandAirTemperature.TheCO40isdesignedusingventedballtechnologyfor
fastresponse(<30seconds)forsensingCOgas.
Theuser‐programmablehighalarmalertstheuseriftheCOlevelrisesabovetheprogrammed
limit.
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buttontopoweronthemeter.Holdthebuttonfor2secondsto
turnoffthemeter.Duringmeasurement,ifthealarmissounding(audiblebeeper)pressthe
buttonmomentarilytoturnoffthebeeper.Pressagaintoactivatethebeeper.Thealarmbeeper
issettoONbydefault.Themetercanbepoweredby4AAAbatteriesorACadaptor.
AutoPowerOff
TheCO40willautomaticallyturnoffafter15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performedastheLCDcountsfrom“9999”downto
“0000”andthenentersthenormalmodeofoperationwheremeasurementsaretakenbythe
sensorsanddisplayedontheLCD.TheupperLCDareashowstheCOreadinginppmandthe
lowerLCDareashowstheairtemperaturereadinginoC/oFunitsofmeasure.
SelectingoC/oFunitsofmeasure
PresstheUNITbuttontoselectthedesiredtemperatureunitofmeasure.
MaximumReadingMemory
MomentarilypresstheMbuttontoviewthemaximumreadingscapturedsincethemeterwas
poweredon(theMAXiconwillbeappear).PressMbuttonagaintoreturntonormaloperation.
DataHold
MomentarilypresstheHOLDbuttontofreezethedisplayedreadings(theHOLDiconwill
appear).PresstheHOLDbuttonagaintoreturntonormaloperation.
Calibration
PressandholdtheMODEbuttonfor2secondstoentertheself‐calibrationmode.Ensurethat
thereisnoCOpresentwhilecalibrating.TheLCDwilldisplay“CAL”and“ooooo”flashing.Wait
forapproximatelyfifteenseconds,untilthecalibrationiscompleted.“End”appearsonthe
screenwhencalibrationhascompleted.Afterfiveseconds,themeterthenreturnstoitsnormal
measurementmode.
