1) IntroductiontoInstrument,Unpackingand

Installing

Thankyouforyourpurchaseanduseofourproducts!Thischapterwillintroducethebasic

instrumentperformance,whichisfollowedbynotesofunpackingandinstalling.

1.1IntroductiontoInstrument

With5‐inch,colorLCDscreenanduniqueinsulationresistance/leakagecurrentdualtestfunction,

U2684InsulationResistanceMeterisanintelligentmeasurementinstrumentthatisusedforrapid

measurementsoninsulatingpropertiesofelectronicpartsandcomponents(especiallythe

capacitance),dielectricmaterial,equipments,wires,cables,etc.

U2684isprovidedwithsortingoutputandexternalsinglepulsesignalinputinterface,makingit

easyforpipelineoperation.Thequippedcommunicationinterfacecanachievetheoff‐site

operationsofallfunctionsoftheinstrumentthroughmicrocomputer.Theinstrumenthasa

powerfulanti‐jammingcapability,whichmakesthemeasurementmorereliable

1.2Unpacking

Inspecttheshippingcontainerfordamageafterunpackingit.Itisnotrecommendedtopoweron

theinstrumentinthecaseofadamagecontainer.

Ifthecontentsinthecontainerdonotconformtothepackinglist,notifyusoryourdealer.

1.3PowerConnection

1) Powersupply:90Vto121Vac(60Hz)or198to242Vac(50Hz).

2) Powersupplypowerrange:≤50VA.

3) L(linewire),N(neutralwire)andE(earthgroundwire)ofthepowersupplyinputsocket

shouldcorrespondtothepowerplugoftheinstrument.

4) Theinstrumenthasbeenspeciallydesignedfordecreasingnoisejammingcausedbytheinput

inACpowerterminal,butitisalsorecommendedtouseitintheenvironmentoflownoise.If

noisescannotbeavoided,installapowersourcefilterplease.



WARNING:Toavoidinjurytopersonnelanddamagetotheinstrumentresultingfromelectric

shock,dosurethattheearthgroundwireissafelygrounded.

1.4Fuse

Thefuseisastandardconfiguration,sousetheincludedcustomfuseplease.

1.5Environment

1) Donotstoreorusetheinstrumentwhereitcouldbeexposedtomanydusts,greatvibration,

directsunshineandcorrosivegas.

2) Theinstrumentshouldoperateunderthetemperaturerangingfrom10℃to40℃,relative

humidityofnogreaterthan90%.Forhighaccuracy,usetheinstrumentintheenvironment

abovementioned.

3) Forhighaccuracy,donotblocktheleftairventsoastoensuregoodventilation.

4) TheinstrumenthasbeenspeciallydesignedfordecreasingnoisejammingcausedbytheAC

powerinput,butitisalsorecommendedtouseitintheenvironmentoflownoise.Ifnoise

cannotbeavoided,installapowerfilterplease.

5) Iftheinstrumentwillnotbeusedforalongtime,pleaseplaceitintheoriginalorasimilar

packingbox.Theenvironmenttemperatureshouldbekeptintherangeof0℃to40℃,and

therelativehumidityshouldnotbegreaterthan90%RH.Theboxshouldbelocatedinanairy

roomwhereitcouldbeexposedcorrosiveimpuritiesanddirectsunlight.

6) TestleadsontheinstrumentthatareconnectedtoDUTsshouldbekeptawayfromstrong

electromagneticfieldstoavoidinterference.

1.6UseofTestFixture

Onlyusethetestfixtureorcablemadebyourcompany,becausetheuseofothertestfixturesor

cablesmayresultinincorrectmeasurementresults.Inaddition,forgoodcontactofDUTandfixture,

keepthetestfixtureorcableandpinsofDUTclean.

ConnectthetestfixtureorcabletoHV(‐)andINPUTterminalsontheinstrumentfrontpanel.

1.7Warm‐up

1) Foraccuratemeasurement,thewarm‐uptimeshouldnotbelessthan30minutes.

2) Donotturnonorofftheinstrumentfrequently.Thismaycauseinternaldataconfusion.

1.8OtherFeatures

1) Consumption:≤30VA

2) Dimensions(W*H*D):350mm*120mm*360mm;thisdimensionisthefinalpackagingsize.
