Introduction

ThankyouforselectingtheExtechAN340CMM/CFMAnemometerPsychrometerDatalogger.This

instrumentmeasuresAirVelocity,AirFlow(volume),AirTemperature,RelativeHumidity,WetBulb

Temperature,andDewPointTemperature.



Themeter’scompactminiimpellerisperfectforductairflowmeasurements.Thesensorprobehas

an18mm(0.7”)diameteranda1M(39”)telescopingprobewandwithamarkedscale.Duct

temperaturedoesnotaffecttheairflowmeasurementresults.Temperatureandhumiditysensors

arebuiltintothevanesensor.



Theusercanmanuallystoreandrecall99readingsdirectlyonthemeter’sLCD.Theusercanalso

automaticallylogupto12,000readingswithdateandtimestampandselectablesamplingrate.

ReadingsaretransferredtoaPCusingthesuppliedPCsoftwareandUSBconnectorcable.



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.

CAUTIONS

Improperuseofthismetercancausedamagetothemeterandpersonalinjury.Readand

understandthisusermanualbeforeoperatingthemeter.

Inspecttheconditionoftheprobeandthemeterforanydamagebeforeoperatingthe

meter.Repairorreplacedamagebeforeuse.

Iftheequipmentisusedinamannernotspecifiedbythemanufacturer,theprotection

providedbytheequipmentmaybeimpaired.

Operation

PowerON‐OFF

1. SwitchthemeterONbypressingthepowerbuttonmomentarily.

2. PressagaintoswitchthemeterOFF.

3. IfthemeterdoesnotswitchON,checkthatthemeterhassix(6)freshAAAbatteries

installedintherearbatterycompartment.Refertothebatteryinstallationsectionfor

details.

4. Themetercanalsobepoweredusingthe9VACpoweradaptor.Thepoweradaptorconnects

tothetopofthemeterusingthejackasshownintheDescriptionsectionofthisguide.

Sleepmode

Themeterwillautomaticallyenterthesleepmode(switchoff)aftertwenty(20)minutesof

inactivity.Todisablethisfeature:withthemeterOFF,pressandholdtheSETandHOLDbuttons

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

unitofmeasure.Tochangetheunitofmeasure,refertotheSETUPmodesection.Thelower

displaylineshowstherealtimeclock,alternatingtimeanddateinformation.

9. Theairtemperatureandrelativehumiditysensorsarelocatedintheslottedopeningonthe

sensorwandbelowtheimpeller.

10. Airvelocityreadingsareindicatedinmeterspersecond(m/s)orfeetperminute(fpm).

Temperaturereadings(air,dewpoint,orwetbulb)areindicatedin°C/°F.RelativeHumidity

isindicatedin%.Airflow(volume)isindicatedinCFM(cubicfeetperminute)orCMM(cubic

metersperminute).

11. Tomeasurerelativehumidityusinganoffsetreferencevalue,pleaseaccesstheSetupmode

andinputtheoffsetvalueasdescribedintheSetupmodesection.TheLCDwilldisplaythe
