CAUTIONS

Improperuseofthismetercancausedamage,shock,injuryordeath.Readandunderstandthisuser

manualbeforeoperatingthemeter.

Alwaysremovethetestleadsbeforereplacingthebatteryorfuses.

Inspecttheconditionofthetestleadsandthemeteritselfforanydamagebeforeoperatingthemeter.

Usegreatcarewhenmakingmeasurementsifthevoltagesaregreaterthan30VACrmsor60VDC.These

voltagesareconsideredashockhazard.

AlwaysdischargecapacitorsandremovepowerfromthedeviceundertestbeforeperformingDiode,

ResistanceorContinuitytests.

Voltagechecksonelectricaloutletscanbedifficultandmisleadingbecauseoftheuncertaintyof

connectiontotherecessedelectricalcontacts.Othermeansshouldbeusedtoensurethattheterminals

arenot"live".

Iftheequipmentisusedinamannernotspecifiedbythemanufacturer,theprotectionprovidedbythe

equipmentmaybeimpaired.

Thisdeviceisnotatoyandmustnotreachchildren’shands.Itcontainshazardousobjectsaswellassmall

partsthatthechildrencouldswallow.

Incasethedeviceisgoingtobeunusedforanextendedperiodoftime,removethebatteriesandstore

themseparately.

Expiredordamagedbatteriescancausecauterizationoncontactwiththeskin.Useprotectivegloves

whenhandling.

Donotshort‐circuitthebatteries.Donotthrowbatteriesintoafire.



Thismeterhasbeendesignedforsafeuse,butmustbeoperatedwithcaution.Theruleslistedbelowmust

becarefullyfollowedforsafeoperation.

4. NEVERconnectthemeterleadsacrossavoltagesourcewhilethefunctionswitchisinthecurrent,

resistance,ordiodemode.Doingsocandamagethemeter.

5. ALWAYSdischargefiltercapacitorsinpowersuppliesanddisconnectthepowerwhenmakingresistance

ordiodetests.

6. ALWAYSturnoffthepoweranddisconnectthetestleadsbeforeopeningthecoverstoreplacethefuse

orbatteries.

7. NEVERoperatethemeterunlessthebackcoverandthebatteryandfusecoversareinplaceandfastened

securely.

8. NEVERchangethemeasurementfunctionbyturningthefunctiondialwhiletesting.

OperatingInstructions

WARNING:Riskofelectrocution.High‐voltagecircuits,bothACandDC,areverydangerousandshouldbe

measuredwithgreatcare.

1. ALWAYSturnthefunctionswitchtotheOFFpositionwhenthemeterisnotinuse.

2. IfOLappearsinthedisplayduringameasurement,thevalueexceedstheselectedrange.

Changetoahigherrange.

3. Ifthemeterdoesnotswitchonwhenthefunctiondialisturnedtoanypositionotherthan

OFF,pleasecheckthebatteries.RefertotheBatteryInstallationsectionofthisguide.

AUTOPOWEROFF(APO)

TheAPOfeatureturnsthemeteroffafter15minutesofinactivity.TodisableAPO,holdthe

SELECTbuttonwhileturningthemeteron.Themeterwillemit5beepsindicatingthatAPOhas
