What does error e-9 mean on an Accu-Chek instant blood glucose monitor?

"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.

The E-1 error usually indicates that the test strip is damaged or improperly inserted. Try removing the test strip and replacing it. Try a different test strip. Open a new box of test strips and try using one from the new box.

I hope this helps. You can find the manual for the Accu-Chek Performa on the product page: https://www.accu-chek.com.au/meter-systems/performa . The direct link to the manual is currently https://www.accu-chek.com.au/download/file/fid/16491 . The error messages and trouble-shooting are to the right-hand side of the page. You will need to scroll a bit.

if you have the blue/silver front version (and probably also if you have black version) of the meter, E-5 means
"The measurement optics are dirty or you

have inserted a test strip that has already

been used or is too old. Clean the

measurement optics (Chapter 7.1) and

repeat the test with a new Accu-Chek
Active Glucose test strip."
