Throughoutthisscreenalltextualresultsinformationfollowthesamemeaningfortextualcoloringasfollows‐
Ifcoloredgoldthenthedataisasconfiguredbyyou.
Ifcoloredwhitethenthedataisshowingameasurement.
Ifcoloredgreenthenthedataindicatesthatthereisnoerrororprecautionarycondition.
Ifcoloredredthenthedataindicatesanerrororprecautionarycondition.
Althoughyoumayonlyviewtheresultsoftheassessment,andmayonlystartanassessment,fromthisscreen,youdonot
needtomaintainviewingthisscreenduringorafteranassessment.Youcanfreelychangebetweenscreenswhilean
assessmentisinprogressandtheresultsofacompletedassessmentareretainedifyouchangetoviewinganotherscreen.
TheresultsofanassessmentareonlylostifyoupowercycletheXT2640,youmakeasignificantchangetothemeasurement

18.4.4.1 TEXTUALRESULTS–SUPPLY
TheSUPPLYareashowsthetextualresultsofmeasurementsmadeonthesupplyvoltageduringtheassessment.Thedatashownare
(inorderfromtoptobottomofthearea)‐
1.
Thepass/failstatusofthesupplychecks(seesection18.1.6.1),notethatthiscoversallphasesofthesupplynotjustthat
selectedtobeviewed.Ifanyfailureisdetectedthenanumericalcodeisshowncoloredredwhichcontainsanindicationofall
detectedfailuresbymeansofaddingthecodesforeachfailure,otherwiseitshowsOKcoloredgreen.Thecodesare‐
1:ThevoltagewasnotwithintheallowedrangefromtheconfiguredUnomvaluethroughouttheassessment.
2:ThefrequencywasnotwithintheallowedrangefromtheconfiguredFnomvaluethroughouttheassessment.
4:Thefrequencychangedbymorethan0.03%duringany200msmeasurementperiod.
8:ThesupplyvoltageharmonicsdidnotmeettherequirementsofEN61000‐3‐2clauseA.2cthroughouttheassessment.
NotethatwhenperformingEN61000‐3‐12assessmentsnocheckingofthesupplyvoltageharmonicsisperformed.
16:ThesupplyvoltagecrestfactorwasnotwithintheallowedrangeperEN61000‐3‐2clauseA.2dthroughoutthe
assessment.NotethatwhenperformingEN61000‐3‐12assessmentsoranEN61000‐3‐2classAorBassessmentisbeing

Recommendations:
Ifcodes1and/or2arefoundtheneithertheassessmentwasnotperformedwiththesupplysourcesetcorrectly,orthe
Unomand/orFnomsettingsintheXT2640wereincorrectlyset.Inthislatercaseyouonlyneedtochangethosesettings
withaREASSESS,intheformercasethesupplysourceneedstobecorrectedandtheentireassessmentrepeated.
Ifcodesotherthan1or2arefoundthenthesupplysourceisnotsuitableforperformingtheassessment.
