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
equipmentappearstobedamaged,leaclaimimmediatelywiththecar-
rierandnotifyyourdistributoratonce,givingadetaileddescriptionofany
damage.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
ModelK100andModelK110arelowcurrentmeasurementinstruments
thatfeatureacompact,highsensitivitycurrentprobe.Unlikeotherinstru-
ments,theModelK100exhibitsawidedynamicoperatingrange,which
extendsfrombelow100µAto±4.5Apeak,fromDCto2.0kHz*,withoutthe
needforranging.TheK110hasanoperatingrangeof100µAto±450mA
Peak,fromDCto1500Hz.*
ModelsK100andK110aredesignedtobeoperatedinconjunctionwitha
digitalmultimeter,oscilloscopeorrecordingdevice.TheMicroProbeout-
putsthecurrentmeasuredintheformofavoltagethatistheimageofthe
current,inshapeandamplitude.TheModelK100outputs1mVpermAof
measuredcurrent.TheModel K110outputs 10mVpermA ofmeasured
current.TotakeadvantageoftheModelK100highsensitivity,bestresults
areobtainedthrough4-1/2digit(ormore)DMMwitharelativezerofunc-
tion.TheModelK110wasdesignedtoprovidetheoperatorwithenhanced
lowcurrentlinearityandaccuracy,butislimitedto450mAPeakcurrent.
The Model K100/K110 always outputs a signal proportional to the total
current(AC+DC)intheconductorundertest.Thishasproventobethe
most versatile signal output format, and allows the user to isolate and
measureDCandAC componentsofmeasuredcurrent separately,ifso
desired.Typicalapplicationsinclude4to20mAloopmeasurements,auto-
motive current applications, benchtop electronic current consumption in
circuits,andotherapplicationsrequiringverylowcurrentmeasurements
incrowdedareas.
