Evaluating test
results After the bar code has been placed under the scan head (when using
the Static Bar Code Evaluation method) or the bar code document has
been fed into the transport (when using the Dynamic Bar Code
Evaluation method), the following message will be displayed:
Bar Code Type=
Please wait…
After approximately 30 seconds of processing time, the results of the bar
code evaluation will be displayed or a message indicating the bar code
was not read will be displayed.
If the display indicates the bar code was not read, it could be for one of
the following reasons:
•
The type of bar code placed under the scan head was not the type
indicated in the status display.
Action: Verify the type of bar code placed under the scan head.
•
The bar code was not positioned properly under the scan head.
Action: Verify the position of the bar code placed under the scan
head.
•
The bar code quality is poor.
Action: Perform required maintenance.
If the bar code evaluation results are displayed, the following information
will help you evaluate these results.
Grade= W/N= :1 Contrast= %
NEW= MOD= % DEF= % RMIN= %
Grade — indicates the overall grade of the bar code evaluation. This
grade is based upon the field values that appear in the remainder of the
display. The fields which appear in the remainder of the display are either
dimensional or reflectance fields.
Each of the reflectance field values are converted to a letter grade (where
A is the highest and F is the lowest). The lowest letter grade assigned to
any one of the reflectance fields is the overall grade assigned to the bar
code.
Dimensional Fields (Pass or Fail)
W/N — the average ratio of wide element widths to narrow element
widths within a bar code. The ratio is calculated for both bars and spaces;
the smallest of the two ratios is displayed.
New — the measure of the smallest Narrow-Element Width.
