WHY IS NO CODE NUMBER APPEARING WHEN TEST STRIPS ARE INSTALLED?

Possibly an Accu-Chek question although this is just a guess searching the internet using https://www.google.com

"E-1" in the display means the test strip may be damaged or the code key isincorrect. Remove and reinsert the test strip. If the message reappears, turn off themeter and make sure the code key is properly inserted. If the message reappears, please contact Accu-Chek Customer Care

Hi There!
An E-1 error, accompanied by an image of a test strip, indicates that the test strip is damaged or the code key is incorrect.

I hope this helps you out!

Is it possible that you are using the wrong machine for your strips? Those machines all look so much alike.

Not enough blood or control solution was drawn into the test strip for measurement or was applied after the test has started. Discard the test strip and repeat the test.

Cant remember exactly but i think that is probable blood incorrectly put onto test strip, probably before meter is ready. You have to wait for the little drop of blood to appear on the display.

Code-1" in the display means the test strip may be damaged

E5 codekey expired which means that the test strips or out of date and no longer any good. You get a new codekey with a new can of test strips. A pain, I know.
E1 Re Insert test strip
E2 Incorrect code key
E3 Extremely high reading
E4 Not enough blood on test strip
E6 Control Solution too soon?
E7 Electronic error
E8 Temperature too high
E9 Change Battery.

This is probably due to not needing a new code chip with each batch of test strips. You do need to keep your last chip but will no longer need to change it. If possible keep more than 1 spare code chip just in case. I know that the site shows this question was posted in early 2014 but I hope this helps

Enough blood on strip?
