5.1Powerthemeter
1. PullandholdthetriggerforonesecondtoswitchthemeterONandbeginscanning
surfacetemperatures.
2. TheTGSeriesispoweredbythree(3)1.5V‘AAA’batteries.Batteriesarelocatedinthe
meter(twistoffthehandlecaptoreleasethebatteryholder).RefertoSection7,
Maintenance,formoredetail.
3. TheBatterystatusiconisshownontheupperrightsideofthedisplay.Thestatusicon
showsfullwhitewhen100%poweredanddarkensasbatterypowerweakens.The
batterystatusiconappearsempty(fullydark)whenthebatteriesrequirechanging.Note
thattemperaturereadingsdisplayedwhilethebatterysymbolisemptywillbeaccurate.
AccuracyisassuredupuntilthemeterswitchesOFF.
4. TheTGSerieshasaprogrammableAPO(AutoPowerOFF)featurewhereitautomatically
shutsoffafterthetriggerisreleased(after5,10,or20seconds).PleaserefertoSection6,
ProgrammingMenu,forinstructionsonsettingtheAPOtime.
5.2TakingMeasurements
1. Beginbypullingandholdingthetriggerforonesecond.
2. Whileholdingthetrigger,scanthesurface(s)undertest.UsetheLaserpointerasaguide.
Noticethatwhilethetriggerispulledthedisplayshowsthescanningiconandlaser
pointericon.
3. Viewthetemperaturereadingandotherinformationonthedisplaywhilescanning.Ifthe
measurementexceedsthepublishedrange,thedisplaywillindicate‘OL’.ReadSection
4.4,MainDisplayDescriptions,andSection4.5,DisplayIconDescriptions,forreference.
4. Tosetthetemperatureunits(oC/oF)pleaserefertoSection6,ProgrammingMenu.
5. Whenthetriggerisreleased,thescanningandlasericonsarereplacedbythe(HOLD)

5.6UsingtheTypeKThermometer(TG56only)
ATypeKthermocouplethermometerjackisprovidedatthetopoftheTG56.Thethermocouple
plughasawideandathinconnectingblade,pleaseinsertthethermocouplecarefully,inthe
correctorientation;donotforceitintothejack.
Whenathermocoupleisconnected,thetemperatureofthesurfaceinwhichthethermocouple
istouchingisdisplayed(nexttotheicon)alongwiththeIRtemperaturereading.
Thedisplaymodeareaofthescreen(middleoftoprowoficons)showsthethermocouple 
iconwhenathermocoupleisconnected.ThedifferencebetweentheIRreadingandthe
thermocouplereadingisdisplayednexttothedeltaicon.
Whenathermocoupleisconnectedtothemeterotheroperationalmodesarenotavailable.
5.6.1UsingtheTypeKThermometertosetEmissivity
1. MeasurethesurfaceoftheobjectundertestwiththeIRThermometer.
2. MeasurethesamesurfacewiththeTypeKthermocouplethermometer.
3. Notethedifference(delta)betweenthetworeadings.
4. NowadjusttheEmissivityintheProgrammingmenu(Section6)sothattheIR
thermometerreadingmatchestheTypeKthermometerreading.
5. Whenthisisaccomplishedtheemissivitysettingiscorrectforthesurfaceinquestion.
Thermocouplenotes:
Thesuppliedgeneralpurposethermocoupleisnotratedfortheentiremeasurement
rangeofthemeter.Thethermocouplecanbedamagediftemperatureoutsideits
specifiedrangeismeasured.Inallcases,pleaseuseathermocouplethatisratedforthe
intendedapplicationonly.RefertothespecificationssectionofthisUserManualfor
metertemperatureandthermocoupletemperatureranges.
Theaccuracycharacteristicsofthethermocoupleprobeshouldbeaddedtotheaccuracy
specificationofthemeterwheninterpretingthermocouplereadings.
TheIRthermometeraveragesalargerareathanthethermocoupleprobe,thusthe
