Testing the Barcode Reader
Ensure that your barcode reader has been correctly installed using the
procedure in Installing the Handheld Barcode Reader. Ensure that the
barcoded labels used in your laboratory comply with the specifications given
later in this section.
1. Obtain a label for which you know the barcode value.
2. Attach the label to a specimen tube or cup.
3. At the Ready/Run screen, select
Menu.
4. Select
Setup.
5. Select
Next Screen eight times to access the ninth Setup screen.
6. Select
Perform hardware tests.
7. Select
Bar code reader.
8. Aim the reader toward the barcode.
9. Press and hold the trigger.
10. Move the reader until the red line crosses the entire width of the barcode.
The reader beeps, and the number displays on the analyzer screen.
11. If the result is not correct, or if the barcode cannot be read, repeat the test
using a new label.
12. If the result is still not correct, refer to Troubleshooting, below.
Troubleshooting
It is important that the labels be printed to the required specifications.
Reading errors may occur if any of the following conditions exist:
• the narrow bar width is too small
• the barcode length too great
• the height too small
• the reader is held too far from the label
• the background reflection too high or low
The test labels included with the barcode reader can be used to verify the
operation of the reader. Two sheets of labels are provided. Each sheet
contains 2 labels in each of the 6 symbology and check digit combinations.
These test labels are of a known quality, printed within the barcode reader
specifications.
If the reader is not able to consistently read your labels, apply a test label of
the format being used to a new specimen tube and perform the Barcode Test.
If the reader is able to read the test label, the quality of your labels may be
suspect. If the test label cannot be read, the reader itself is suspect.
