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.

OPERATION
4.1 Current Measurement
WARNING: Always connect the probe to the instrument before
clampingontothecircuitundertest.
• ConnecttheModelMN261totheproperinputchannelonthe
oscilloscope.
• Beginwiththeleastsensitiverangeonthecurrentprobe(10mV/A).
• Selectthe0.5V/Divisionrangeontheoscilloscope.
• Clamptheprobeontheconductortobemeasuredandreadthe
currentowingdirectlyonyouroscilloscope.
(Remember to unclamp the probe from the conductor before disconnect-
ing it from your meter or instrument.)
You may also use your oscilloscope to amplify the signal while using
the1mV/Aproberange(whichoffersthebestaccuracyandleastphase
shift).
NOTE: Itispossibletochangetherangeonthecurrentprobewith-
outremovingtheprobefromthecurrentcarryingconductor,butitis
importanttoremembernottoexceedthepermissiblepeakratings
of340mVpeakor680mVpeaktopeakmaximum.Thepeakratings
byrangeare:34Apeak@100mV/Aand340Apeak@10mV/A.

MAINTENANCE
5.1 Maintenance
WARNING
• Toensureoptimumperformance,itisimportanttokeeptheprobe
jawmatingsurfacescleanatalltimes.Failuretodosomayresult
inerrorinreadings.
• Formaintenanceuseonlyspeciedfactoryreplacementparts.
• Toavoidelectricalshock,donotattempttoperformanyservicing
unlessyouarequaliedtodoso.
• Toavoidelectricalshockand/ordamagetotheinstrument,donot
allowwaterorotherforeignsubstancesintothecase.
• Disconnecttheunitfromallcircuitsandtestcablesbeforeopen-
ingthecase.
• Usecautionwithmetallictoolsthatmayshortbatterypacks,power
supplies,etc.
5.2 Cleaning
• Tocleantheprobebody,useasoftclothdampenedinasolution
ofmilddetergentandwater.Tocleanthecore,openthejawand
cleantheexposedcoresurfaceswithacottonswabdampened
withisopropylalcoholorethylalcohol.Lubricatethejawsmating
surfaceswithalightoil.
• Do not use chemicals containing benzine, benzene, toluene,
xylene,acetone,orsimilarsolvents.
• Donotimmersetheprobeinliquidsoruseabrasivecleaners.
