5. ReleasetheTrigger;thereadingwillHOLDforthetime

setintheAPOsetting.Thebacklightwillturnoffafterapproximately4seconds.

6. Themeterdefaultstotheprogrammedconditionsinusewhenthemeterwaslastswitched

LaserPointer

Thelaserpointercircleidentifiestheareabeing

measured.Thesizeoftheareaisdeterminedbythe

distancetospotratio.Objectsoutsidethecircleare

notmeasured.Thespotmeasuredshouldalwaysbe

UVLeakDetector

Injectasmallamountofflorescentdyeintothesystemundertest.Thedye/systemmixture

(refrigerant,forexample)willescapeandaccumulateatallleaksites.TurntheblueUVLEDson

intheSettingmodeandscanthesystem.Theresidueofthedyeattheleakcanbeeasily

observedundertheUVlight.DyesareavailableatmostHVACsupplyoutlets.



LocatingHotorColdSpots

Todetectahotorcoldspot,aimthethermometerataregionbeyond

thetargetandthenscantheentireregioninaslow,up/downmotion.



DistancetoSpotRatio(FieldofView)

Themeter’sfieldofviewis12:1(distancetospotratio).Forexample,ifthemeteris60cm(24

inches)fromthetarget(spot),thediameterofthetargetmustbeatleast5cm(2inches).Other

distancesareshownbelowinthefieldofviewdiagram.

Notethatmeasurementsshouldnormallybemadefurtherthan60cm(24inches)fromthe

target.Themetercanmeasurefromfurtherdistancesbutthemeasurementmaybeaffectedby

externalsourcesoflight.Inaddition,thespotsizemaybesolargethatitencompassessurface

areasnotintendedtobemeasured.

2.5cm@30cm5cm@60cm10cm@120cm

1”@12”2”@24”4”@48”



Itisnecessarytoensurethatthesizeofthetargetislargerthanthespotsize.Thesmallerthe

target,thecloserthedistanceshouldbe.

Emissivity

Emissivityrepresentstheenergyreflectivityofamaterial.Mostorganicmaterialsandpainted

oroxidizedsurfaceshaveanemissivityofapproximately0.95.Ifpossible,maskingtapeorflat

blackpaintshouldbeappliedtocoverthemeasuredsurface.

Waitaperiodoftimetoallowthetapeorpainttoreachthermalequilibriumwiththesurface

ofthecoveredobject.Measurethetemperatureofthesurfacecoveredwithtapeorpaintonly

afterequilibriumhasbeenachieved.

HighLowLimits

TheHI/LOlimitsprovideanalarmwhenapresettemperatureisexceeded.

LensCover

Thelenscoverprotectsthelensfromdustwhenthemeterisnotinuse.Alwaysclosethecover

whenstoringthemeter.

MeasurementNotes

1. Theobjectundertestshouldbelargerthanthespot(target)sizecalculatedbythefieldof

viewdiagram.

2. Ifthesurfaceoftheobjectundertestiscoveredwithfrost,oil,grime,etc.,cleanbefore

takingmeasurements.

3. Ifanobject'ssurfaceishighlyreflectiveapplymaskingtapeorflatblackpainttothesurface

beforemeasuring.

4. Themetermaynotmakeaccuratemeasurementsthroughtransparentsurfacessuchas

glass.

5. Steam,dust,smoke,etc.canobscuremeasurements.

6. Themetercompensatesfordeviationsinambienttemperature.Itcan,however,takeupto

30minutesforthemetertoadjusttoextremelywideambienttemperaturechanges.

7. Tofindahotspot,aimthemeteroutsidetheareaofinterestthenscanacross(inanupand

downmotion)untilthehotspotislocated.

8. Whenthemeterisheldattheoptimumdistancefromthetarget,thesinglelaserdotwill

appearatthetopofthecircularlasertarget.Aslongasthesinglelaserdotiswithinthe

circularlasertarget,themeterwillmakeanaccuratemeasurement.

Maintenance

Cleaning

Tocleanthelensusecompressedairtocleardustandotherparticles,thencarefullycleanwitha

wetcottonswab.Thecottonswabshouldbemoistenedwithcleanwater.

Tocleanthemeterhousing,wipewithadamp,softcloth.Donotusesolventsorabrasives.Do

notimmersetheIR300UVinwaterorotherliquid.

ReplacingBatteries

Whenthebatteryiconindicatesalowbattery,orwhenthemeter

doesn’tswitchON,replacethebatteries.

Thebatterycompartmentlidislocatedontherearofthehandle.

RemovetheonePhilipsheadscrewandliftthelidoff.

Replacethethree1.5VAAbatteriesfollowingcorrectpolarityandthen

replaceandsecurethebatterycompartmentlid.

BatterySafetyNotes:Pleasedisposeofbatteriesresponsibly;neverdisposeof

batteriesinafire,batteriesmayexplodeorleak.Ifthemeterisnottobeused

for60daysormore,removethebatteryandstoreseparately.Donotmix

batterytypesorfreshnesslevels;pleaseusebatteriesofthesametypeandofthesamefreshnesslevel.

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

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

retailstorewherethebatterieswerepurchased,orwhereverbatteriesaresold.

Disposal:Donotdisposeofthisinstrumentinhouseholdwaste.Theuserisobligatedtotakeend‐of‐life
