2. SafetyInformation

Toensurethesafeoperationandserviceofthemeter,followtheseinstructionsclosely.Failureto

observewarningscanresultinsevereinjury.

WARNINGS

WARNINGSidentifyhazardousconditionsandactionsthatcouldcauseBODILYHARMorDEATH.

Whenhandlingtestleadsorprobes,keephandsandfingersbehindthefingerguardsatalltimes.To

avoidelectricalshockdonottouchexposedelectricalwire,connectors,unusedinputterminals,or

circuitsundertest.

Removetestleadsfromthemeterbeforeopeningthebatterycompartmentormeterhousing.

UsethemeteronlyasspecifiedinthisUserGuideoraccompanyingQuickStarttoavoidcompromising

theprotectionsprovidedbythemeter.

Besuretousetheproperterminals,switchpositions,andrangeswhentakingmeasurements.

Verifythemeter’soperationbymeasuringaknownvoltage.Havethemeterservicedifthemeter

respondsunusuallyoriftherearequestionsregardingthemeter’sfunctionalintegrity.

Donotapplymorethantheratedvoltage,asmarkedonthemeter,betweenterminalsorbetweenany

terminalandearthground.

Donotmeasurevoltagesabove1000VDCor600VACbetweenterminalandgroundtopreventelectrical

shockanddamagetotheClampmeter.

Usecautionworkingwithvoltagesabove30VACRMS,42VACpeak,or60VDC.Thesevoltagesposea

shockhazard.

Toavoidmisleadingreadingsthatcouldleadtoelectricshockandinjury,replacethebatteriesassoonas

thelowbatteryindicatorisdisplayed.

Disconnectpowertothecircuitundertestanddischargeallhigh‐voltagecapacitorsbeforetesting

resistance,continuity,diodes,orcapacitance.

Donotusethemeterinthepresenceofexplosivegasorvapor.

Toreduceriskoffireorelectricshock,donotusethemeterifitiswetanddonotexposethemeterto

moisture.

IndividualprotectiveequipmentshouldbeusedifHAZARDOUSLIVEpartsintheinstallationwhere

measurementsaretobecarriedoutcouldbeaccessible.

CAUTIONS

CAUTIONSidentifyconditionsandactionsthatcouldcauseDAMAGEtothemeterorequipment

undertest.Donotexposethemetertoextremesintemperatureorhighhumidity.

Disconnectthetestleadsfromthetestpointsbeforechangingthepositionofthefunction(rotary)

switch.

Donotexposethemetertoextremesintemperatureortohighhumidity.

Neversetthemetertotheresistance,diode,capacitance,micro‐amp,orampfunctionswhen

measuringthevoltageofapowersupplycircuit;thiscouldresultinmeterdamageanddamagetothe

equipmentundertest.

CAUTION:ReadandunderstandalloftheSafetystatementslistedinthesafetysection

ofthismanualpriortouse.

PoweringtheMeter

1. Turntherotaryfunctionswitchtoanypositiontopowerthemeter.Checkthebatteriesifthe

unitfailstopowerON.RefertotheMaintenancesectionforbatteryreplacement.

2. TurnthefunctionswitchtotheOFFpositiontopowerOFFthemeter.

3. ThemeterhasanAutoPowerOFFfeature(APO)wherethemeterswitchesOFFafter15

minutesofinactivity.WhenAPOisenabled,theAPOiconwillshowonthedisplaywhenthe

meterispoweredON,

Thelowbatterysymbolappearsonthedisplaywhenthebatteryvoltageweakensbelowthe

threshold.

DisplayBacklight

WiththemeterpoweredON,pressandholdthebacklightbuttontoswitchthebacklightONor

OFF.Notethatexcessiveuseofthebacklightwillshortenthebatterylife.

WorkLight

WiththemeterpoweredON,presstheWorkLightbuttonontherightsideofthemeter.A

momentarypresswillswitchtheWorkLightoff.TheWorkLightlampislocatedonthebackofthe

unittowardthebottomoftheclampjaw.Notethatexcessiveuseofthebacklightwillshortenthe

batterylife.

DataHold

TofreezetheLCDmeterreading,presstheDataHold(H)button.Whiledataholdisactive,theH

displayiconappearsontheLCD.Pressthe(H)buttontoreturntonormaloperation.TheHiconwill

switchOFF.

TestLeadConsiderations

TestleadprobecoverscanberemovedforCATII1000Vinstallations.Usethetestleadprobe

WARNING:

RemovethetestleadprobecoversforCATII1000Vinstallations.Usethetestleadprobecovers

forCATIII600Vinstallations.

Donotmeasurevoltagesgreaterthan600VACor1000VDC.

CAUTION:Whenconnectingthetestleadstothecircuitordeviceundertest,connectthe

blackleadbeforethered;whenremovingthetestleads,removetheredbeforetheblacklead.

Disconnectprobesandcircuitundertestafterallmeasurementsarecompleted.

1. Inserttheblacktestleadbananaplugintothenegative(COM)jackandtheredtestlead

bananaplugintothepositive(V/Ω)jack.

2. Turnthefunctionswitchtotheposition.UsetheMbuttontoselectAC.

3. ReadtheWarningandCautionstatementsabovetodeterminewhetherornottousethe
