A meter or test strip error has occurred.
Repeat the blood glucose test.

If a second E-3 code appears, perform a control test with the control solution and a new test strip.

• If the control result is within the acceptable range, review the  roper testing procedure and repeat the blood glucose test with a new test strip.
• If the control result is not within the acceptable range, see the Understanding Out-of-Range Control Results section in the User Manual.

This error 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.

In rare cases, an E-3 error code may indicate that your blood glucose is extremely high and above the system’s reading range.

If you do not feel like your blood glucose is extremely high, repeat the blood glucose test. See the Unusual Blood Glucose Results section in the User Manual.

If the E-3 code still appears for your blood glucose test, contact your healthcare professional immediately.

Discard the test strip and repeat the blood glucose or control test.
