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).

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.

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
