Introduction

CongratulationsonyourpurchaseoftheExtechAN320VaneAirflowAnemometerPsychrometer

+CO2.ThisinstrumentmeasuresAirVelocity,AirFlow(volume),AirTemperature,Relative

Humidity,WetBulbTemperature,DewPointTemperature,andCO2(carbondioxide).Thelarge,

easy‐to‐readbacklitLCDincludesprimaryandsecondarydisplaysplusnumerousstatusindicators.

Theoptionalroundandsquareairflowconeadaptorsallowforquickairflow(volume)

measurements.Thismeter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

AirVelocityandAirVolumeMeasurements

1. SwitchthemeterONbypressingthePOWER buttonmomentarily.Themeterwill

countdownfrom30to0asitperformsaself‐test.PressthePOWERbuttonagaintoswitch

themeterOFF.

2. Notethatthemeterwillautomaticallyenterthesleepmodeafter20minutesofinactivity.

Todisablethisfeature:withthemeterOFF,pressandholdthePOWERandtheU/mode

buttonsfor2seconds.TheLCDwilldisplay'n'asitswitchesON.Nowthesleepmodeis

disabledandtheusermustpressthePOWERbuttonmomentarilytoswitchthemeterOFF.

3. WhenthemeterisON,theupperdisplaycanindicate

airvelocity,relativehumidity,orCO2(usetheU/mode

buttontoscroll).Thelowerdisplaydigitscanindicate

airflow,dewpointtemperature,wetbulbtemperature,

orairtemperature(usetheL/modebuttontoscroll).

4. Placethesensorintheairstream.Theairmustenter

thevanefromtherearofthemeter.TheAir

Temperature,Relativehumidity,andCO2sensorsarelocatedatthecenterofthevaneon

therearofthemeter.

5. ReadthemeasurementdataontheLCD.Airvelocityreadingsareindicatedinmetersper

second(m/s)orfeetperminute(fpm).Temperaturereadings(air,dewpointDP,orwetbulb

WBT)areindicatedin°C/°F.Airflow(volume)isindicatedinCFM(cubicfeetperminute)or

CMM(cubicmetersperminute).UsetheL/modebutton(forlowerdisplay)andtheU/mode

button(forupperdisplay)toscrollthroughthedisplayedreadingoptions.

6. TochangebetweenImperialandMetricunitsofmeasurerefertotheSETUPModesection.

areacalculations)andthenentertheareavalueinthemeter’sSETUPmodeinin2orcm2.

Aftertheareavaluehasbeenentered,usetheL/modebuttontoscrolltotheairvolume

display(CMM/CFM)onthelowerdigits.Placethemeterinairstreamtomeasurevolume.

8. Optional:measureAirVolumewithanairflowConeorSquareadaptorbyfirstattachingone

oftheadaptorstothemeter(theoptionalconeadaptorkitincludesaroundandasquare

cone;kitpartnumberAN300‐C).Themeterwillautomaticallyrecognizethattheadaptoris

attachedtothemeterandaconeiconwillappearonthedisplay.Note:regardlessofthe

AREAsettingintheSETUPmode,themeterwilldefaulttothedimensionsofthevane

opening.Ensurethattheairflowadaptoriswellmountedandlockedbeforetaking

measurements.

LCDbacklight

PresstheU/modebuttontoswitchONtheLCDbacklight.Thebacklightwillautomaticallyswitch

OFFafterapproximately10secondstoconservebatterypower.Notethatthebacklighting

switchesONautomaticallywhenthemeterisswitchedONbytheuser.
