Storing injector setpoints
Procedure: Configuring the bar code reader
The bar code reader can be configured to read specific codes on the bar code
label.
1. To edit the bar code reader setpoints, press [Config][Sample Tray].
2. Press [On] or [Off] to control the following bar code setpoints.
Enable 3 of 9—the 3 of 9 code offers the greatest versatility for
laboratory use. It can encode both letters and numbers, plus a few
punctuation marks, and message length can be varied to suit both the amount
of data to be encoded and the space available.
Enable 2 of 5—the 2 of 5 code is restricted to numbers but does allow
variable message length.
Enable UPC code—the Universal Product Code (UPC) is probably the
most well-known code in use today. UPC codes are numbers-only and have
fixed message length.
3. Enter 3 as the bar code reader position when it is installed in the front of the
tray.
For more information on the bar code reader, refer to its Operating Manual or
Installation Manual.
Storing injector setpoints
After setting up injector setpoints, sample tray setpoints and bar code reader
configurations, store them as part of a method by following the procedures in
chapter 8, “Analytical Methods.” This method becomes a part of the sequence
used to run the samples.
