Testing bar codes When the bar code zone is first created, Capture Software automatically sets the orientation to the orientation of the bar code, if found. Otherwise, Horizontal is selected by default. 5. Enter a Confidence level when you want to restrict what Capture Software considers to be a successful bar code read. When reading a bar code, the Capture Software bar code reader indicates how confident it was in correctly reading the bar code. If this confidence percentage (between 0 to 100%) falls below the specified confidence level, then a bar code value is not returned. 6. Change the quality level if desired. Settings range from Worst (0) to Best (9). The highest quality bar codes are printed by a laser printer or pre-printed with an offset printer. Lower quality bar codes are printed with inkjet or dotmatrix technology. Depending on the quality of bar codes being scanned, set the Quality level accordingly. The higher the quality setting, the faster bar code read performance is. 7. Enable Minimum partial read characters when you want Capture Software to generate a bar code value, even if a bar code is incomplete. If enabled, enter the minimum number of characters that will be allowed for a partial read. This is useful for bar codes that are only used for document or batch separation where the absolute value is less critical. NOTES: For indexing purposes, it is recommended that you define field masks and minimum lengths in such a way that it is possible to detect partially read bar codes, thereby causing index field audit errors. Capture Software will not produce any bar code value if the bar code is incomplete and the Minimum partial read characters field is disabled. Minimum Partial Read should not be used when Verify Checksum is enabled, as this may result in a bar code value being generated when checksum verification fails. When a bar code zone is first drawn, Capture Software will attempt to read or test the bar code in the defined zone. If successful, the bar code value will be displayed in the Value box in the upper right of the Bar Code Zone Properties window. If unsuccessful, the Value box will be empty. When editing a bar code zone, click the Test button to test the bar code. If successful, the bar code value will be displayed. If unsuccessful, the message No bar code found appears. Make any changes to the bar code properties, then click the Test button again to re-test the bar code. A-63054 February 2004 6-15
