flowmeterdigitalinput(DI)channe l#2isgrounded,themeterinitiatesthezero‐mid‐spandrift
checksequence.Whilethesystemisbusyperformingthedriftchecksequence,itwillnotaccept
another
commandviathedigitalinput.Afterthedriftchecksequencecompletes,themeter
monitorstheDIchannelforthenextrequesttoinitiateadriftcheck.
Ifaspecifiedtimeinternaldriftcheckisunderwaywhileanexternaldriftcheckistriggered,the
