Operation

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

1. SwitchthemeterONbypressingthePOWERbuttonmomentarily.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orrelativehumidity(usetheU/modebutton

totoggle).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andRelativehumidity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,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).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.

7. TomeasuretheAirVolumeofaduct,firstmeasuretheduct’sarea(seetheAppendixfor

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.

AN310-en-GB_V1.5 11/15

RelativeHumidity,WetBulb,andDewPointMeasurements

Therelativehumiditysensorisbuiltintothecenterofthevane(rearofmeter)andcanbeusedto

measurerelativehumidity,dewpointandwetbulbtemperatures.

1. PressU/modetoswitchtothe%RHdisplayifnecessary.Themeasuredhumidityreadings

willbedisplayedontheupperLCDdigits.

2. UsetheL/modebuttontoscrollthroughairtemperature,dewpointtemperature,wetbulb

temperature,andairvolumereadings.

3. Tomeasurethe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

measuredvalueminustheoffsetvalueoncetheoffsetisprogrammedintheSetupmode.
