Reviewing the Dimensional Parameters
The following table lists the dimensional parameters and summarizes their
results. 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 Parameters
If, after a scan, the abbreviation for dimensional appears as >DIM<, an error
exists in one or more of the dimensional parameters. If there is an error, use the
arrow buttons to review each parameter to identify the problem. If the
abbreviation for dimensional appears as Dim, the symbol has no dimensional
errors.
Average Bar
The average bar print error (AvgBar) value is the amount of average bar growth
or loss in the measured symbol relative to its “X” dimension. This value is
compared against traditional print tolerance criteria and rated. If the AvgBar is
within these limits, it is rated OK! or pass. If the AvgBar is outside these limits,
this test fails.
