Quick Check® 600/800 Series User’s Guide 4 - 9Reviewing the Dimensional ParametersThe following table lists the dimensional parameters and summarizes theirresults. Descriptions of the parameters follow the tables.* The method you select (Avg Decode or ISO/IECISO/IEC) determines the scan and sym-bol grades.Errors in Dimensional ParametersIf, after a scan, the abbreviation for dimensional appears as >DIM<, an errorexists in one or more of the dimensional parameters. If there is an error, use thearrow buttons to review each parameter to identify the problem. If theabbreviation for dimensional appears as Dim, the symbol has no dimensionalerrors.Average BarThe average bar print error (AvgBar) value is the amount of average bar growthor loss in the measured symbol relative to its “X” dimension. This value iscompared against traditional print tolerance criteria and rated. If the AvgBar iswithin these limits, it is rated OK! or pass. If the AvgBar is outside these limits,this test fails.Parameter Trad’l ISO/IECAverage Bar Error (Avg Bar Err) √Wide-to-narrow ratio (Wide/Nar Ratio) √Decodability* √Parameter ResultAvg Bar Err Compared against traditional print tolerance crite-ria set by symbology or applicationOK if within criteriaFail if outside criteriaWide/Narrow Ratio Compared against generic or user set limits for thesymbology or applicationOK if within limitsFail if outside limitsDecodability A if > .62B if > .50C if > .37D if > .25F if < .25
