Description
TheSCal‐400isamulti‐unitchargingandcalibrationstationforSensitP400gasdetectioninstruments.Itcanbumptestand/or
calibrateuptofiveP400unitsconsecutivelywhilesimultaneouslyrechargingthebatterypacks.TheSCal‐400alsodetectsifa
P400requirescalibrationorabumptestwhenconnectedandautomaticallyperformstherequiredtest.Duringconnection
anymanuallyperformedcalibrationandbumptestsintheinstrumentmemorylogwillautomaticallytransferfromP400to
SCal‐400.DatamanagementfortheSCal‐400requireseitherSCal‐DorSCal‐Nsoftwarepackages.AllSCal‐400stationscome
standardwithSCal‐Dsoftwarefordesktopapplication.
Thelocationtoplaceanyinstrumentisreferredtoasa“slot”.Foreachslottherearechargerandcommunicationconnections
aswellasLEDstoindicatethestatus.Alltestingfunctionsrequirenouserinteraction.
Thedisplayisatouchscreen.Instrumentandstationinformationcanbeaccessedbyusingyourfingerortheincludedstylus.
TheSCal‐400scanseachslot,updatestheLEDstatus,andrefreshesthedisplayscreenforeachsloteverythreeseconds.During
communication,theSCal‐400completesanylogtransferbeforescanninganotherslot.
