INTRODUCTION

WARNING

Thesesafetywarningsareprovidedtoensurethesafetyofperson-

nelandproperoperationoftheinstrument.

• Connect the probe to the oscilloscope or voltage measuring

instrumentbeforeclampingtheprobearoundaconductor.

• Neverusetheprobeoncircuitsratedhigherthan600V,CatIII.

• Neverleavetheprobeclampedaroundaconductorwhilenot

connectedtoanoscilloscopeorvoltagemeasuringinstrument.

• Carefullycentertheconductorinsidetheprobejawsandascer-

tainthattheprobeisperpendiculartotheconductor.

• Avoid,ifpossible,theproximityofotherconductorswhichmay

create noise.

• Checkthemagneticmatingsurfacesoftheprobejaws;these

shouldbefreeofdirt,rust,orotherforeignmatter.

• Donotuseaprobewhichiscracked,damaged,orhasdefec-

tive leads.

1.1 International Electrical Symbols

Thissymbol signiesthat the instrument is protectedby doubleor

reinforced insulation. Use only specied replacement parts when

servicingtheinstrument.

Thissymbolon the instrumentindicatesa WARNINGandthat the

operatormustrefertotheusermanualforinstructionsbeforeoperat-

ingtheinstrument.Inthismanual,thesymbolprecedinginstructions

indicatesthatiftheinstructionsarenotfollowed,bodilyinjury,instal-

lation/sampleandproductdamagemayresult.

Risk of electric shock. The voltage at the parts marked with this

symbolmaybedangerous.

ThisisatypeAcurrentsensor.Thissymbolsigniesthatapplication

aroundandremovalfromHAZARDOUSLIVEconductorsispermitted.

1.2 Deﬁnition of Measurement Categories

Cat. I: Formeasurementsoncircuits notdirectlyconnectedto theAC

supply wall outlet such as protected secondaries, signal level,

andlimitedenergycircuits.

Cat. II: For measurements performed on circuits directly connected to

the electrical distribution system. Examples are measurements

onhouseholdappliancesorportabletools.

Cat. III: For measurements performed in the building installation at

the distribution level such as on hardwired equipment in xed

installationandcircuitbreakers.

Cat. IV: For measurements performed at the primary electrical supply

(<1000V) such as on primary overcurrent protection devices,

ripplecontrolunits,ormeters.

1.3 Receiving Your Shipment

Uponreceivingyourshipment,makesurethatthecontentsareconsistent

withthepackinglist.Notifyyourdistributorofanymissingitems.Iftheequip-

mentappearstobedamaged,leaclaimimmediatelywiththecarrierand

notifyyourdistributoratonce,givingadetaileddescriptionofanydamage.

PRODUCT FEATURES

2.1 Description

TheACCurrentOscilloscopeProbeModelMN261expandsoscilloscope

applicationsinindustrialorpowerenvironments,andisidealforanalysis

andmeasurementofdistortedcurrentwaveformsandharmonics.

TheModelMN261permitsaccuratedisplayandmeasurementofcurrents

from0.1to240Arms,40Hzto10kHz(withcurrentderating)withoutbreak-

ingintothecircuit.Apassiveltereliminatesnoise,ringonrapidrising(di/

dt)waveforms,andensuresaccuratescreendisplays.

Theprobeconnectsdirectlytoanoscilloscopethroughaninsulatedcoax-

ialcablewithaninsulatedBNC.

2.2 Compatibility

TheModelMN261iscompatiblewithanyanalogordigitaloscilloscopeor

othervoltage-measuringinstrumentwhichhasthefollowingfeatures:

• BNCinputconnector

• Rangecapableofdisplaying0.2to0.5Vperdivision,or2Vrange

• Minimuminputimpedanceof1MΩ
