Meter Maintenance and Troubleshooting
A meter or test strip error has occurred.
This error message could appear if the
cap on the test strip container was not
closed tightly. The test strips may have
been damaged due to improper storage
or handling.
Never make therapy decisions based
on an error message.
Repeat the blood glucose test. If a
second E-3 error message appears,
perform a control test with the control
solution and a new test strip. See the
section Performing a Control Test in the
chapter Control Tests. If you continue to
receive an E-3 error message, use an
alternate method for testing your blood
glucose, such as a back-up meter and
test strip. If the alternate method gives
an extremely high blood glucose result,
or if an alternate method is not
available, contact your healthcare
professional immediately.
In rare cases, an E-3 error message
may indicate that your blood glucose is
extremely high and above the system's
measuring range. See the Unusual
Blood Glucose Results section in the
chapter Blood Glucose Tests for other
possible causes of the error
message.
