Operation

MeterPower

One9Vbatterypowersthemeter.PullthemetertriggertoswitchthemeterON.Ifthemeter

doesnotswitchON,pleasecheckthebattery(locatedinthemeterhandle);refertothe

Maintenancesectionformoreinformation.Thebatteryiconprovidesbatterystatus;replacethe

batteryassoonasthebatteryiconflashes.ThemeterswitchesOFFsevensecondsafteryou

releasethetrigger(duringtheseven‐secondperiodthelastreadingfreezesonthedisplay).

SurfaceTemperatureMeasurements

1. Holdthemeterbyitshandleandpointittowardthesurfaceundertest.

2. PullandholdthetriggertoturnthemeterONandtoscansurfacetemperatures.Withthe

triggerpulledtheSCANiconflashesintheupperleftareaofthedisplay.Readthemeasured

temperatureintheprimarydisplayarea.

3. If‘HI’appearsonthemainLCDdigits,thetemperaturereadingexceedsthehighrangeofthe

meter.

4. Releasethetrigger;thereadingwillholdforapproximately7seconds,andthenthemeterwill

automaticallyshutoff.

5. RefertotheFieldofViewsectionfordistancetotarget(spot)ratioconsiderations.

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

OFF.Forexample,ifthelaserissettodefault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PointerandLCDBacklightDefaultModes

PresstheMbuttonorpull/releasethetriggertoturnthemeterON.Now,pressandreleasethe

buttontostepthroughthesedefaultconditions:

LaserON/BacklightOFF

LaserON/BacklightON

LaserOFF/BacklightOFF

LaserOFF/BacklightON

Whenyouenablethelaser,thelasericon appearsontheupperleft.Tousethelaser,pulland

holdthetriggerandaimthelaserapproximatelyonehalfinchabovethepointoftest.

SelectingtheTemperatureUnitofMeasure(°C/°F)

WiththemeterON,longpresstheMbuttontoswitchthetemperatureunits.Thedisplaybeeps

andswitchesbetween°Cand°F.

LocatingHotorColdSpots

Tolocateahotorcoldspotwhilescanning,aimthemeteroutsidetheareaofinterestthenscan

(inanupanddownmotion)untilthespotislocated.

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12inchesfromthetarget(spot),the

diameterofthetargetmustbeatleast1inch.Refertothe

fieldofviewdiagramprintedonthemeterandreproduced

here.

Measuresurfacesfromamaximumdistanceof2feetwheneverpossible.Themetercanmeasure

fromfurtherdistancesbutexternalsourcesoflightmayinterferewiththereadingsandthespot

sizemaybesolargethatitencompassesunintendedsurfaceareas.

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.

MeasurementConsiderations

1. Theobjectundertestshouldbelargerthanthespot(target)size(refertothefieldofview

sectionabove).

2. Removefrost,oil,grime,etc.,fromsurface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butitcantakeupto30

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

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

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

SecondaryDisplayModes

Thesecondarydisplayareaislocatedonthebottomofthemeter’sLCD.Youcanstepthroughthe

secondarydisplaymodesbysimplyshortpressingtheMODE(M)buttonfromapoweredONor

poweredOFFcondition.

Themodeiconappearsonthelowerleftanditsassociatedvalueappearsonthelowerright

(exceptforemissivity;itsvalueappearsontheupperright).Usethearrowbuttonstomake

changestoasettingwhereapplicable.Refertothesections,below,fordetailedinformationfor

eachmode.

Forbestresults,pullandreleasethetriggertoswitchthemeterON,usetheMbuttontoselect

thedesiredmode,andthenpullthetriggertobeginmeasuringwiththedesiredmodenowactive.

MaximumReading(MAX)

UsetheMbuttontosteptotheMAXparameter,thenpullandholdthetriggertostartscanning

surfacetemperatures.Thereadingonthelowerrightrepresentsthehighestreadingrecorded

duringthecurrentmeasurementscan.WhenpressingMfromapoweredOFFcondition,the

valueshownonthelowerrightisthehighestreadingrecordedduringthelastmeasurement

scanperformed.

MinimumReading(MIN)

UsetheMbuttontosteptotheMINparameter,thenpullandholdthetriggertostartscanning

surfacetemperatures.Thereadingonthelowerrightrepresentsthelowestreadingrecorded

valueshownonthelowerrightisthelowestreadingrecordedduringthelastmeasurementscan

performed.

DifferentialReading(DIF=MAXminusMIN)

UsetheMbuttontosteptotheDIFparameter,thenpullandholdthetriggertostartscanning

surfacetemperatures.Thereadingonthelowerrightrepresentsthedifferencebetweenthe

MAXandtheMINreadingsrecordedduringthecurrentmeasurementscan.WhenpressingM

fromapoweredOFFcondition,thevalueshownonthelowerrightrepresentsthedifference

betweentheMAXandtheMINreadingsrecordedduringthelastmeasurementscanperformed.

AverageReading(AVG)

UsetheMbuttontosteptotheAVGparameter,thenpullandholdthetriggertostartscanning

surfacetemperatures.Thereadingonthelowerrightrepresentstheaverageofallreadings

condition,thevalueshownonthelowerrightistheaverageofallreadingsrecordedduringthe

lastmeasurementscanperformed.

HighAlarmLimit(HAL)

UsetheMbuttontosteptotheHALparameter.UsethearrowbuttonstosettheHighAlarm

limit.Whilemeasuring,themeterbeepswhenthedisplayedreadingishigherthanthehigh

alarmsetting.Ifthebacklightison,thebacklightcolorwillturnredinahighalarmcondition.

LowAlarmLimit(LAL)

UsetheMbuttontosteptotheLALparameter.UsethearrowbuttonstosettheLowAlarm

limit.Whilemeasuring,themeterbeepswhenthedisplayedreadingislowerthanthelowalarm

setting.Ifthebacklightison,thebacklightcolorwillturnblueinalowalarmcondition.

DatalogMemory(LOG)

Themeterhastwentymemorylocations(1~20)inwhichtostoredtemperaturereadings.

1. FromapoweredONorOFFcondition,shortpresstheMbuttontosteptotheLOGmode

(theLOGdisplayiconismuchsmallerthantheothermodeicons)

2. Usethearrowstoselectamemorylocationinwhichtostoreareading

3. Pullandholdthetriggertoscansurfacetemperatures

4. Pressthebuttonatanytimetostorethereadingintheselectedmemorylocation.

Notethatyoucanpressthebuttonafterthetriggerisreleasedinordertostorethe

Emissivityrepresentsthereflectivityofamaterial.Forthismeter,theemissivitycanbeadjusted

from0.10~1.00(seeEmissivityAdjustsectionabove).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.
