The E03 error message on your Contour Next EZ blood glucose meter signifies that the device has detected either a used test strip or an incorrect control solution. This error code is a critical indicator that prevents inaccurate blood glucose readings, ensuring the reliability of your test results.
Understanding the specific causes behind the E03 error can help you quickly resolve the issue and continue monitoring your blood sugar effectively.
Understanding the E03 Error Code
The E03 error code on your Contour Next EZ meter points to two primary reasons:
| What You See | What It Means |
|---|---|
| E03 | • The meter is sensing a used test strip. |
| • The wrong control solution was used. |
Resolving the E03 Error
To address the E03 error and ensure accurate readings, consider the following solutions based on the identified cause:
1. Used Test Strip Detected
Your Contour Next EZ meter is designed to detect and prevent the reuse of test strips. If the meter senses a test strip that has already been used, it will display the E03 error.
- Solution: Always ensure you are using a new, unused CONTOUR NEXT test strip for each blood glucose test. Discard any previously used or damaged test strips immediately. Verify that the test strip vial has been properly sealed to prevent contamination or damage to the remaining strips.
2. Incorrect Control Solution Applied
Control solutions are used to check if your meter and test strips are working correctly. Using the wrong type of control solution can lead to an E03 error.
- Solution: Confirm that you are using the correct CONTOUR NEXT control solution specifically designed for your Contour Next EZ meter and CONTOUR NEXT test strips. Check the expiry date on the control solution bottle; expired solutions can also cause inaccurate results or errors.
By addressing these specific issues, you can quickly clear the E03 error and ensure the accurate and reliable performance of your Contour Next EZ blood glucose meter. For more detailed information, you can refer to the official Contour Next EZ support resources.
