Energy‐counters
WARNING!

Beforemodification, allenergycounters should bereadorif energy valuesarestoredin
recorders,recordershouldbereadwithMiQensoftwareorstoredonMemorycardtoassure
dataconsistencyforthepast.
Aftermodificationofenergyparameters,theenergymeters(counters)shouldbereset.All
recordedmeasurementsfromthispointbackmighthavewrongvaluessotheyshouldnot
be transferred to any system for data acquisition and analysis. Data stored before
modificationshouldbeusedforthispurpose.
Activetariff  
Whenactivetariffisset,oneofthetariffsisdefinedasactive;switchingbetweentariffsisdoneeitherwitha
tariffclockoratariffinput.Fortheoperationofthetariffclockotherparametersofthetariffclockthatare
accessibleonlyviacommunicationorMemorycardmustbesetcorrectly.
