What Do the Accu-Chek Aviva Error Codes Mean?
The Accu-chek Aviva blood glucose monitor's LCD screen features a number of error display options. The range of codes and their meanings are explained in the user manual for the device at the Accu-chek official website.
According to the Accu-chek website, the error codes designated by "E-" followed by a number explain common errors. 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. An E-2 error indicates an incorrect code key. Errors designated E-3 suggest unusually high blood glucose levels or a testing strip error.
A second test attempt is needed to correct an E-4 error, which occurs when not enough blood or solution is drawn. E-5 means the code key entered is from an expired batch of test strips. If E-6 is encountered, blood or solution was applied to the test strip before the device was prepared. E-7 indicates an electronic error or the reuse of a used test strip. E-8 means that the temperature is too high to test properly, and E-9 requires a battery replacement. E10 is displayed when date and time settings may be incorrect, states Accu-chek.
Some Aviva models display "Err" instead of a numbered code. These devices indicate the error using the icons associated with the errors listed above. The sole exception is EEE, which indicates an electronic error, according to Accu-chek.
