• Always zero theModel K100/K110 prior tomaking ameasure-ment.See§4.1forprocedure.

• Makesure thatprobe jawmatingsurfacesare freeofdustandcontamination. Contaminants cause air gaps between sensorhalves, making the Model K100/K110 susceptible to externalmagneticfieldswhichcancontributetomeasurementerrors.See§5.3forcleaningprocedure.

• Donotallowprobe jaws toabruptlysnapclosed fromtheopenstate. This can lead to residual readings. If this happens, theModelK100/K110willneedtoberezeroed.

• Bewareofshort-circuitcurrents.Largein-rushcurrents(whichcanoccurwhenpowerisfirstappliedinacircuit)andlargehigh-cur-renttransientsmaycausevaryingdegreesofresidualreadings.Ifindoubtofaparticularreading,removetheprobefromthecon-ductorundertestandchecktoseethatthedisplaydevicereturnszero.Ifnot,itwillbenecessarytorezerotheModelK100/K110.

• WhenusingtheModelK100/K110tomeasureACcurrents,keepinmindthemaximumcurrentratingsandthefrequencyresponsecurves shown in the electrical specifications section. Dynamiccurrents thatcontain largestepdiscontinuitiesand/or frequencyconstituents near or beyond the measurement passband aresubject tomeasurementserrorsandwaveformdistortion (oscil-loscopedisplay).IftheredLEDcomesonduringmeasurement,theMicroProbe’soutputsignalmaybeinerror.

ManyDVMsprovidenull(relative)measurementcapability.ADVMplacedinthenullmodedisplaysthedifferencebetweenastorednullvalueandtheinputsignal.

• YoucanuseaDVM’snullfunctioninplaceoftheexternalDCzerocontrol to cancel anyDCoffset from theK100/K110.TheDVMnullfunctionshouldbeenabledwiththeproberemovedfromtheconductorimmediatelybeforemeasurement.

• You canuseaDVM’snull function todisplay changes inmea-suredcurrentfromafixed(constant)level.Inthisapplication,theDVMnullfunctionisenabledwiththeprobeconnectedtothecon-ductor.

Whenmaking null (relative)measurements, the probe aperture current(notdisplayedcurrent)mustnotexceedthemaximumratingssetforthinthespecificationssection.


4.6 Residual Readings Following Severe OverloadsLarge short-circuit and transient currents outside the operating rangeof theModelK100/K110maycause largeresidualreadings. Inextremecases,theModelK100/K110willnotzero.Ifthishappens:

• Removetheprobefromthetestconductor.

• Open the probe and release, allowing the jaws to snap back.Repeatthisstepseveraltimes.

• Rezerotheinstrumentbeforemakingsuccessivemeasurements.
