    "E-7" in the display means an electronic error occurred or, in rare cases, a used test strip was removed and reinserted. Turn the meter off and on or take the battery out for 20 seconds and reinsert it. Perform a blood glucose or control test. If the problem persists, please contact Accu-Chek Customer Care.
