WIRING:SettothewiringconfigurationwhichyouusedtowiretotheXT2640.
g) That’sitforconfiguration.PressthePOWERDATAbuttontosavetheconfigurationandtostartseeingthe
measurements.
6) Youcanapplyvoltagetoyourapplicationnow.
7) Selectwhatresultstolookat.
Viewingresultsisjustasinglepressononeoftheupper7buttonsdowntherightsideofthescreentoviewthatscreen.On
eachofthesescreensyoucanselectseveraldifferentwaysoflookingatthemeasurements.Inallcasesthebuttonsacrossthe
topofeachscreenallowsyoutoselectwhatyou’relookingat.Abriefsummaryofeachscreenisasfollows–
POWERDATA:enablesyoutoviewnumericalresultsfor–
Allvoltage,current,andpower(W,VA,VARandPF)measurements;inpeak,RMS,fundamentalonly,orrectified
forms.
Inrush.
Resistive,inductiveandcapacitiveloading.
Integratedandlong‐termaveragemeasurements(e.g.Watt‐Hours).
Efficiencyandpowerloss.
CUSTOMDATA:enablesyoutoviewjustaboutanynumericaldatayouwish,alongwithdescriptivetext.Youcan
configureawidevarietyofformatsforthisscreen.
HARMONICS:enablesyoutoviewvoltage,current,power,andinter‐phasevoltageharmonicsinbothgraphicaland
numericalformats.
VECTORS:enablesyoutoviewsingleormulti‐channelvoltageandcurrentgraphicallyasvectorsonapolarchart.
HISTORY:enablesyoutoseewhat’shappenedinthepastwithoutneedingconfigurationbeforehand.Givesagraphical
chartofmostmeasurementresultswithpowerfulzoomingcapabilities.
SCOPE:enablesyoutoviewthevoltage,current,powerandinter‐phasevoltagewaveformswithoutneedingconfiguration
(CYCLEVIEW),ortousetheXT2640asapowerfuloscilloscope(SCOPEVIEW).
STBYPOWER:enablesyoutoconfigure,runandviewtheresultsofEN50564lowpowermeasurementsinbothnumerical
andgraphicalformats.
ASSESSEUT:enablesyoutoconfigure,performandviewtheresultsofEN61000‐3‐2or‐12assessmentsofaEUT(if
measurementshavebeenconfiguredtodoso).
TheXT2640rememberswhatyouhaveconfigured,whichresultsscreenyouarelookingat,andhowyouhavesetupthatscreen.If
youturnofftheXT2640,whenyouturnitbackonitisconfiguredjustlikeyouleftit.Butit’sbesttoremovepowerfromyour
applicationwhenturningofftheXT2640.
TheXT2640alwaysmeasureseverythingconfiguredtobemeasured;measurementsarenotdependentonwhichscreenyou’re
lookingat.So,forexample,youcanconfigureanoscilloscopecaptureontheSCOPEscreen,changetoanotherscreenandthencome
backtotheSCOPEscreenlatertoseewhat’sbeencaptured.
IfyoursignalshaveinstabilitythentheresultsdisplayedbytheXT2640willrespondtothatinstabilitypossiblymakingresults
difficulttoread.InthosesituationsyoushouldgobacktotheMEASCONFIGforthatVPAandadjustoneormoreofthefollowing
settings–
SettheRESPONSEsettingtoaslowerresponse.Thisaveragesallresultsoveranumberofmeasurementperiods.
SettheLF/PERIODsettingtoalongermeasurementperiod.Thisslowsdownthechangesintheresults.
SettheDIGITSsettingtolessdisplayeddigits.Thisreducestheresolutiononmostnumericalresults.
SimplyexportingascreenimagetoaUSBdrivefileenablesyoutodocumentyourresultsforanyscreen.Youcanalsoexportand
importconfigurationsto/fromfilesonaUSBdrive,givingyouthefreedomtoexperimentwithconfigurationsettingswithout
worryingaboutbeingabletoreturntoapriorknownconfiguration.Seesection13fordetailsregardingthis.
