Cannot perform set-up for Accu-Chek Performa

"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.

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

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.

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

The information you need is in the reference guide for your meter.

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."
