About the Barcode Reader

60
When used with an Agilent data system and the optional
headspace control software, the barcode reader provides the
data on the vial label to the data system for inclusion in
reports. Also, mismatches between the expected barcode
value, as entered into the data system sequence, and the
barcode actually read will be logged and can trigger specific
actions.
Depending on the symbology selected, using the barcode
reader provides up to 3 checks on the vial:
• A check for a mismatch between the barcode value
entered in the data system sequence and the value read
from the vial label.
• A check for the barcode checksum, if supported by the
barcode label symbology.
• Whether or not the barcode reader was able to read the
vial's barcode label.
The method provides a sequence action to allow you to
process each of these types of checks separately. So, you can
set the sequence to continue if the checksum fails, but abort
if there is a mismatch between the expected and actual
values, for example.
