Specifications
Barcode Formats
The Clinitek Advantus barcode reader meets the requirements of ASTM
E1466-92, “Standard Specification for Use of Barcodes on Specimen Tubes
in the Clinical Laboratory” (available from ASTM, 100 Barr Harbor Dr., West
Conshohocken, PA 19428).
Barcode Symbols and Labels
The barcode symbols, and the labels themselves, must meet certain
specifications, detailed below:
Number of Characters: 1 to 30 data characters. A maximum of 13 characters
can be displayed, stored and transmitted by the Clinitek Advantus analyzer.
Excess characters must be removed as leading or trailing characters.
Narrow Bar Width: 0.15 to 0.51 mm (0.006 to 0.02 in). It is better to be closer
to the upper limit (0.51 mm/0.02 inch), as long as the entire barcode can be
contained within the maximum length.
This measurement effects both the symbol length and how far away from the
label you can hold the handheld barcode reader. If the narrow bar width is at
the minimum, the symbol length can be no greater than 90 mm (3.5 in),
including quiet zones, and the reader can be held no more than 75 mm (3 in)
away.
Narrow to Wide Ratio: Must be within the specifications for the format being
used. This is generally 2.0 to 3.0.
Symbol Length: Variable. See Narrow Bar Width for more information.
Quiet Zone: Minimum of ten times the narrow bar width at each end of the
symbol.
Symbol Height: Minimum of 10 mm (0.40 in).
Total Size of Label: May be greater than the size of the symbol to allow for
printing of human readable information. Printing of the specimen ID number
in alphanumeric digits is strongly recommended.
Symbol grade: Minimum grade of “C” as defined by ANSI X3.182-1990
(available from American National Standards Institute, 1430 Broadway, New
York, NY 10018).
Wavelength of Light: 630 nm (visible red LED).
