*1:Thevalueconvertedtovolumetricowrateatstandardcondition(20°C1barometricpressure(101kPa)relativehumidity65%RH)
(Forgasesotherthanair,20°C,1atmosphericpressure(101kPa),relativehumidity0%RH.)
*2:Thedisplaysofvariousowratesareasshownbelow.
*3:Theintegratingowisacalculated(reference)value.Whenusingtheintegrationmaintainingfunction,becarefulthatthenumberoftimes
maintaineddoesnotexceedthenumberofaccesstimesofthestorageelement(thelimitis1milliontimes).(Changestothesettingsare
countedinnumberofaccesses.)
Wheninstantaneousowrateisbelow1%itisnotcountedasintegratingow.
*4:Usedrygaswhichdoesnotcontaincorrosiveelementssuchaschlorine,sulfuroracids,andwhichiscleananddoesnotcontaindustor
oilmist.Whenusingcompressedair,usecleanairthatcomplieswithJISB8392-1:2012Class1.1.1to1.6.2.Compressedairfromthe
compressorcontainsdrain(water,oiloxide,foreignsubstances,etc.).Tomaintainthefunctionofthisproduct,installalter,airdryer(min.
pressuredewpoint10°Corless),andoilmistlter(max.oilcontent0.1mg/m

)ontheprimaryside(upstreamside)ofthisproduct.(Refer
totherecommendedvaluesonpage42.)
*5:Compressedairisusedforadjustingandinspectingthisproduct.Accuracyforgastypesotherthanairisaguideline.
*6:TheaccuracyisbasedonCKD'sbasicowratemeter.Itdoesnotshowabsoluteaccuracy.
*7:Repeatabilityoverashortperiodoftime.Changeovertimeisnotincluded.(Refertotheproductspecicationssheetfordetails.)
*8:Actualresponsetimemaydifferdependingonpipingconditions.Settingresponsetimecanbeselectedfrombetween50msecto1.5sec.
*9:Theoutputimpedanceoftheanalogoutputsectionisapprox.1kΩ.Iftheimpedanceoftheconnectingloadissmall,outputanderror
increase.Checkerrorwiththeimpedanceoftheconnectingloadbeforeusing.
*10: Thepowersupplyvoltagespecicationsdifferforthevoltageoutputandcurrentoutput.
*11: Currentforwhen24VDCisconnectedandnoloadisapplied.Thecurrentconsumptionwillvarydependingonhowtheloadisconnected.
*12:Gascanbechangedtoargon,carbondioxide,andargon80%+carbondioxide20%withthegaschangefunction.Fullscaleowrate
andanalogoutputafterchanginggasisasfollows.(Notethatthe500L/minand1,000L/minmodelsdonothaveagaschangefunction.)
