INTRODUCTION

WARNING

The safety warnings are provided to ensure the safety of

personnel and proper operation of the instrument. Read the

instruction completely.

• Usecautiononanycircuit:potentiallyhighvoltagesandcurrents

maybepresentandmayposeashockhazard.

• Donot usethe probeif damaged.Alwaysconnectthecurrent

probetothemeasuringdevicebeforeitisconnectedaroundthe

conductor

• Donotuseonnoninsulatedconductorwithapotentialtoground

greaterthan600VCATIIIpollution2.Useextremecautionwhen

clampingaroundbareconductorsorbusbars.

• Beforeeachuse,inspecttheprobe;lookforcracksinhousingor

outputcableinsulation.

• Donotuseclampinwetenvironmentorinlocationsthathazard-

ousgasesexist.

• Donotusetheprobeanywherebeyondthetactilebarrier.

1.1 International Electrical Symbols

This symbol signiﬁes that the instrument is protected by double or rein-

forced insulation.

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

must refer to the user manual for instructions before operating the

instrument. In this manual, the symbol preceding instructions indicates that

if the instructions are not followed, bodily injury, installation/sample and

product damage may result.

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

be dangerous.

This symbol refers to a type A current sensor. This symbol signiﬁes that

application around and removal from HAZARDOUS LIVE conductors is per-

mitted.

Probe ﬁtted with an electronic output limiter providing protection against

voltage surges caused by the accidental opening of the probe secondary

circuit to 30V max. peak.

In conformity with WEEE 2002/96/EC.

1.2 Deﬁnition of Measurement Categories

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.Savethedamagedpackingcontainertosubstantiateyourclaim.

PRODUCT FEATURES

2.1 Description

TheACCurrentOscilloscopeProbeModelSR661expandsoscilloscope

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

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

TheModelSR661permitsaccuratedisplayandmeasurementofcurrents

from100mAto1000Arms,1Hzto100kHz(withcurrentderating)without

breaking 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SR661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
