Memory(MC350andMC350Honly)
Measurementsandalarmscanbestoredinabuiltin8MBflashmemory. All recordsstored in memoryare
accessibleviacommunicationwithMiQensoftware.
Memorydivision 
MCmemoryisdividedinto3partitionswhichsizeisdefinedbytheuser.MeasurementsarestoredinAandB
partitions,whileallalarmsthatoccurredarerecordedinanalarmpartition.
Memoryoperation  
MemoryfunctionsinacyclicmodeincompliancewiththeFIFOmethod.Thismeansthatonlythelatestrecords
arestoredinthememorythatwillreplacetheoldestones.Anumberofstoreddataorastoringperioddepends
onselectedpartitionsize,anumberofrecordedquantitiesandtimeofdivisionsampling.Occupancyofpartitions
isshownintheInformationmenu(seechapterDisplayofdeviceinfoonpage28).
Memoryclearing 
Thereisusuallynoneedtoclearthememory,becauseitworksincyclicmode.Ifyouwanttoclearmemorydata
anyway,thedatastoringmustbestoppedfirst.ReadthedevicesettingswithMiQenandset“Recorderstate”in
Memorysettinggrouptostopped.DownloadchangestothedeviceandopenMemoryinfoformandthenclick
onClearmemorybutton. Select memorypartitionstobeclearedonMemory clearing formand clickon OK
button.Set“Recorderstate”settingbacktoactive.

WARNING!

Itisstronglyadvisedtodownloadrecordervaluesbeforeapplyinganychangestorecorder
or changes of settings for energy, type of connection, current and voltage transformer
settings,usedcurrentandvoltageranges...
Thesechangesmighthaveimpactonrecordedhistorysodatamightnolongerbevalid.
RecordersAandBsetting 
Separately,foreachoftherecorders,settingscanbeset:

Storageinterval:setsatimeintervalforreadingstobewrittentoarecorder

Recordedquantities:foreachof16measurements,whicharetoberecordeditispossibletosetarequiredvalue
anditsrepresentationwithinstorageinterval(minimum,maximum…).

Parameter:heremonitoringquantitycanbeselectedfromalistofsupportedmeasurements.

Value:representationofavaluewithinsetmonitoringintervalcanbesettodifferentconditions.
 Averagevaluerepresentscalculatedaveragevalue
 Actualvaluerepresentsvalueofrecordedquantityatsamplingintervals
 Minimum and Maximum value represents minimum or maximum of recorded quantity in selected
storageinterval.Minimumormaximuminthiscaserepresentsaveragedvalueaccordingtoaverage
intervalselectedinGeneralsettings(seepage25).
