What does e 6 mean on a accu check meter?

The "E6" error code on an Accu-Chek meter typically indicates a problem with the meter's internal components or a malfunction related to the test strips. It may suggest that the test strips are expired, damaged, or not inserted correctly. To resolve the issue, users should check the expiration date of the test strips, ensure they are properly inserted, and, if the problem persists, consult the user manual or contact customer support for assistance.
