Measurements

A. AirVelocityMeasurements

1. UsetheModebuttontosteptotheAnemometermode(An).InAnemometermode,

thedisplaywillshowAirVelocityandTemperature.

2. PressUnitbuttontoselectdesiredunitofmeasure(FPM,MPH,KNOT,KM/H,orM/S).

3. FacetheAirFlowSensorintothesourceoftheairstream.

4. Allowtimeforthereadingtostabilizeandthennotethevalueonthedisplay.

B. RelativeHumidityandAmbientAirTemperatureMeasurements

1. UsetheModebuttontosteptotheRHmode(rH).InRHmode,thedisplaywillshow

theRelativeHumidityreading(upperright)andtheTemperaturereading(lowerleft).

2. Pressthe°C/°Fbuttontoselectthedesiredtemperatureunitofmeasure.

C. TemperatureMeasurementsUsingTypeKThermocouple

1. UsetheModebuttontosteptotheTypeKTemperaturemode(tP).InTemperature

mode,thedisplaywillshowonlythethermocoupletemperature.

2. Plugthethermocoupleintothemeter'sthermocoupleinputjackonthefaceofthe

meter.Ifnothermocoupleisconnected,orifthethermocoupleisdefective,themeter

willdisplaydashes.

3. Pressthe°C/°Fbuttontoselectthedesiredtemperatureunitofmeasure.

D. LightMeasurements

1. UsetheModebuttontosteptotheLightMetermode(Light).Forconvenience,theLCD

displayisorientated180°fromalloftheotherfunctiondisplays.

2. PresstheLux/Ft‐cdbuttontoselectLuxorFootcandleunitsofmeasure.

3. Beforemakingmeasurements‘zero’themeterbyblockingthelightsensor(tocausea

‘nolight’condition)andpressingtheZbutton.Thereadingshouldzero.

4. Tomeasurelight,positionthemetersothatthelightsourceshinesasdirectlyas

possibleonthemeter’slightsensordome.Notethereadingonthedisplay.

E. Airflow(CFM,CMM)Measurements

1. UsetheModebuttontoselecttheAirFlowmode(AirFL).InAirflowmode,themeter

canmeasurethevolumeofairmovingthroughaduct,forexample.Thedisplaywill

showtheCFM(cubicfeetperminute)orCMM(cubicmetersperminute)uniticonon

thebottomofdisplay.UsetheUNITbuttontotoggleCFMandCMMunits.

2. PresstheAreabutton(A)andthenusethe and▲▼buttonstoprogramthearea

value.PresstheREC/Enterbuttontosavetheareavalue.Seethe‘UsefulEquations’

sectionforhelponcalculatingtheareaofaductorotherairway.

3. Forairflowmeasurementstheareaunitsaremeterssquaredorfeetsquared.The

lowerdisplaywillshowm‐2(forCMM)orF‐2(forCFM).

4. Theareasettingrangeis0.001to30.000meterssquaredor0.01to322.92feet

squared.

5. Afterprogrammingthearea,facetheanemometersensorintothewindsourceand

notetheCFMorCMMairvolumereading.

MIN,MAX,DataRecordingFunction

1. PresstheRecbuttononce.TheRECsymbolwillappearonthedisplay.Thisstartsthe

Min/MaxDataRecordingsession.

2. PressRecagainandtheRECMAXsymbol,alongwiththemaximumvalue,willappearonthe

display.

3. PresstheRecagainandtheRECMINsymbol,alongwiththeminimumvalue,willappearon

thedisplay.

4. Toerase(reset)therecordedMaxorMinvaluespresstheHOLDbuttononce(whileinthe

RecordmodewitheithertheMAXortheMINiconshowing).

5. PressandHoldtheRecbuttonfor2secondstoexittheMin/MaxDataRecordModeandto

returntothenormalmode.RECandMAX/MINiconswilldisappear.

DataHold

PresstheHOLDbuttontofreezethereadinginthedisplay.The'HOLD'iconwillappearonthe

upperright‐handsideofthedisplay.PresstheHOLDbuttonagaintoreturntonormaloperation

(the'HOLD'holdiconwilldisappear).

NotethattheAutopowerofffunctionisdisabledintheMax/Minrecordingmode.

BatteryReplacement

WhenthelowbatteryiconappearsorwhenthemeterwillnotswitchONpleasereplacethe

battery.Thebatterycompartmentislocatedonthebackofthemeter,securedbyaPhillipshead

screw.Openthecompartmentandreplacethe9Vbatteryobservingcorrectpolarity.Donot

switchthemeterONuntilthebatterycompartmentissecuredwiththescrew.

Neverdisposeofusedbatteriesorrechargeablebatteriesinhouseholdwaste.

Asconsumers,usersarelegallyrequiredtotakeusedbatteriestoappropriate
