Configuration When the Data Update Interval Is Auto
Set the following items.
Synchronization Source
• Thesynchronizationsourcethatyouwillsetinthissectionisaspecialsynchronizationsourcethat
is used only when the data update interval is Auto is used.*
* Fordetailsonsynchronizationsources,seesection2.8.
• Youcanselectthesynchronizationsourcefromtheoptionslistedbelow.ThedefaultvalueisU1for
the WT310E/WT310EH and I1 for the WT332E/WT333E.
• U1:Thesynchronizationsourceissettothevoltageofelement1.
• I1:Thesynchronizationsourceissettothecurrentofelement1.
• U2:Thesynchronizationsourceissettothevoltageofelement2.(WT333Eonly)
• I2:Thesynchronizationsourceissettothecurrentofelement2.(WT333Eonly)
• U3:Thesynchronizationsourceissettothevoltageofelement3.(WT332EandWT333E)
• I3:Thesynchronizationsourceissettothecurrentofelement3.(WT332EandWT333E)
Timeout
• Timeoutisthetimelimitfordetectingtheperiodoftheinputwaveform.
• Select1s,5s,10s,or20s.Thedefaultvalueis1s.
• Iftheinputsignalfrequencyislowandtheperiodofthesynchronizationsourcecannotbedetected
within the timeout period, the frequency data will be outside the measurement range and will result
in error. The measurement functions of normal measurement determine measured values using the
entire period up to the timeout as the measurement period.
Functional Limitations
The following limitations apply when the data update interval is set to Auto.
• Theintegrationfunctioncannotbeused.Ifyoutrytostartit,error886willoccur.
• Themeasurementdatastoragefunctioncannotbeused.Ifyoutrytostartit,error886willoccur.
