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

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.

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
