Programming Worksheets
TheprogrammingworksheetsprovideaconvenientmethodofdefiningtheRealScan
74programbeforeloadingitintotheunit.EachworksheetrelatestoaParameter
Program.
Theprogrammingworksheetspermittheexactsequenceoftagstoscanforeach
programmingparametertobedetermined.Italsoprovidesahardcopyof
the
programforpossiblefutureuse.
Thetophalfofeachworksheetidentifiestheprogrammingparametersandthe
specifictagsforeachone.Mostoftheworksheetscontainarrowsthatguidethrough
thepropersequence.Thebottomhalfofeachworksheetprovidesaplacetowritein
eachselection.
Most
oftheworksheetscontainshortcutsthatpermitspecificparameterstobeentered
withoutenteringtheentireworksheet.Theseparametershaveanalphacharacterina
boxjustleftoftheparametername.ScanningtheHextagthatcorrespondstothe
alphacharacterenablesinputforthatparameter.Scanthetagsthat
pertaintothat
parameter.Afterenteringthespecifiedparameter,theprogramreturnstoProgram
