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 Performing a Control Test section in the chapter Control Tests within the user manual. 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.
