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
