E5 on an Accu-Chek meter typically indicates a problem with the blood glucose test strip, such as an error in the strip insertion or that the strip is expired or damaged. It may also suggest that the meter is not functioning properly. To resolve this issue, try reinserting a new test strip or checking the expiration date. If the problem persists, refer to the user manual or contact customer support for further assistance.
