USB Port ASCII Commands
ASCIIcommandsallowcommunicatingwiththeflowmeterusingacustomsoftwa reapplication
oraterminalemulator.ESCcommandsallowyoutoobtaintheprocessdataofthemeter.Referto

Built-In Diagnostics
Theflowmeterhasanextensivesetofinternalandexternalsensorandwiringchecksitperforms
andreports.Thediagnostictoolsprovideservicetechniciansupportandminimizetheamountof
meterdown‐time.Intermittenteventsarealsocapturedforevaluationandallowforfaster
correctiveaction.Somediagnostictoolsare
designedfortheuserinterface,whileothertoolsare
usedviaModbus,aterminalemulator,orKzComm.Thediagnostictoolsare:
• Eventcodeswithtextdescriptionappearonthedisplay.
(ThesealsocanbeechoedtotheserialUSBport.)
• Internaleventlogscontaining200FIFOrecordsoftheeventcodeandmeterruntime.
• Min/maxeventmemoryrecords20dailyextremeseachforvelocity,flowrate,process
temperature,electronicstemperature,andtheoccurrenceruntime.
• Trenddatafor20,416recordscapturedevery10secondsinvolatilememory.Thispermits
approximately56hoursofflowrate,temperature,andrun‐timedatawhilethemeteris
poweredon.
• CurrenteventcodeormeterstatusreadviatheModbusregisters,asdescribedin“Internal
VolatileRAMDataLogging”onpage 4‐9.
• NE‐43alarm,below3.6mAorabove21mA,whichmapsmanyoftheerrorstoNE‐43
alarms.
• AdvanceddiagnosticdataaccessiblethroughtheDisplaymodemenuassistswith
troubleshooting byprovidingnumericdatatosupplementtheeventcode.See“Advanced
DiagnosticsMenus”onpage 4‐11foradditionalinformation.
