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25VAC

rmsor35VDC.Thesevoltagesareconsideredashockhazard.

Warning!ThisisaclassAequipment.Thisequipmentcancauseinterferencein

residentialareas;inthesecasestheoperatormayberequiredtotakestepsto

avoidorminimizetheinterference.

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.

Donotleavebatteriesandpackingmaterialunattended;theycanbedangerousin

thehandsofchildren.

Intheeventthatthedeviceisgoingtobeunusedforanextendedperiodoftime,

removethebatteries.

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

Always,therefore,usesuitableglovesinsuchcases.

Ensurethatthebatteriesarenotshort‐circuited.Neverincineratebatteries.
