The display should also show a pound sign (#) indicating the test is a control
solution test. This shows that the number will not be counted in the 7, 14, 30,
60 and 90-day averages. The pound sign (#) will also be displayed when
reviewing the results stored in memory.
If the result falls outside the indicated control range:
• Confirm you are matching the correct range. Control Solution 1 results
should be matched to the CTRL 1 range printed on the test strip vial (or on
the foil pouch).
• Check the expiration date of the test strip and control solution. Make sure
that the test strip vial and control solution bottle have not been opened for
more than 6 months. Discard any test strips or control solution that has
expired.
• Confirm the temperature in which you are testing is between 10 and 40 °C
(50-104 °F).
• Make sure that the test strip vial and control solution bottle have been
tightly capped.
