Operation
MeterPower
Themeterispoweredbytwo1.5VAAbatteries.Withfreshbatteriesinstalled,themeter
switchesONwhenthetriggerispulled.Thebatteriesarelocatedinthemeterhandle;pullthe
batterycompartmentlidawayfromthebodyofthemetertoopen.RefertotheMaintenance
sectionformoreBatteryInstallationinstructions.Thebatteryiconprovidesbatterystatus
indication.Replacethebatteriesassoonasthebatterystatusiconflashes.
SurfaceTemperatureMeasurements
1. HoldthemeterbyitsHandleGripandpointittowardthesurfacetobemeasured.Readthe
FieldofViewsectionbelowfordistancetotarget(spot)ratioinformation.
2. PullandholdtheTriggertoturnthemeteronandbegintestinginScanmode.Thedisplay
willlightifthetwo1.5Vbatteriesaregood.Replacethebatteriesifthedisplaydoesnotlight.
3. ReleasetheTrigger;thereadingwillholdforapproximately9seconds,afterwhichthemeter
willautomaticallyshutoff.
4. Themeterdefaultstotheprogrammedconditionsinusewhenthemeterwaslastswitched
OFF.Forexample,ifthelaserissettoONandthetemperatureunitsaresettooFatthetime
theunitisswitchedOFF,theunitwillswitchONandusethesamesettings.
Laser–ON/OFF
Pull the trigger and release.
PushandHOLDthe buttonforabout3secondstoswitchthelaserpointerONorOFF.
TheLasericonwillflashwhenthestatehaschanged.WhenthelaserisON,thelasericon will
appearontheLCD.Aimtheredlaserbeamapproximatelyahalfinchbelowthepointoftest
(pressingtheLaserbuttonagainturnsthelaseroff).
MAX‐MINMode
Pressthetriggerandrelease.
PresstheMAX‐MINbuttontoviewthemaximumtemperaturereading(MAX),pressagainto
viewthelowestreading(MIN).PressandholdtheMAX‐MINbuttontoswitchtheMAX‐MIN
modeoff.
DisplayBacklight

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24inches
fromthetarget(spot),thediameterofthetargetmustbeatleast2inches.Otherdistancesare
shownbelowinthefieldofviewdiagram.
Notethatmeasurementsshouldnormallybemadecloserthan2feet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.

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.Seetheaccompanyingdiagram.

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.

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.
Maintenance
Cleaning
Tocleanthelenses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IR260inwaterorotherliquid.

ReplacingBatteries
Whenthebatteryiconflashes,orwhenthemeterdoesn’tswitchON,replacethebatteries.
Thebatterycompartmentislocatedinthehandlegrip.Thebatterycompartmentlidislocated
justbelowthetrigger.Prythecompartmentlidofftoreachthecompartment.
Replacethe1.5VAAbatteriesfollowingcorrectpolarityandthenclose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devicestoadesignatedcollectionpointforthedisposalofelectricalandelectronic
