Checksum Algorithm
A
The decoder:
•
Turns the reader on.
•
Decodes information that comes from the reader.
•
Keeps the reader on for up to 4 seconds.
•
Turns the reader off.
•
Sends the decoded information (or no-read message) to the MCL.
To prevent incorrect identification of sample tubes, do not use FNC1, FNC4, and FS (hexadecimal 1C)
characters in your bar-code information.
Checksum Algorithm
Beckman Coulter strongly recommends the use of bar code checksums to provide automatic checks
for read accuracy.
Use of bar codes is an extremely accurate and effective method of positive patient identification.
Certain features, such as checksum digits, maximize accuracy in reading Codabar, Code 39 and
Interleaved 2-of-5 labels. In one study, the use of checksum digits detected 97% of misread errors.
Use checksums to provide protection against occasional misread errors caused by problems such as
damaged or misapplied labels. If you must use bar codes without checksums, Beckman Coulter
recommends that you verify each bar-code reading to assure correct patient identification.
