Numerous error display settings are available on the LCD screen of the Accu-chek Aviva blood glucose monitor. The user handbook for the gadget is available online at the Accu-chek official website, and it explains the variety of codes and their meanings.
The error codes denoted by “E-” followed by a number describe common errors, according to the Accu-chek website. An E-1 error with a test strip image next to it means that either the test strip is broken or the code key is off.
An erroneous code key would result in an E-2 error. A testing strip error or very high blood glucose levels are suggested by errors with the code E-3.
When insufficient blood or solution is drawn, an E-4 error happens and needs to be fixed with a new test. E-5 denotes that the code key input came from a batch of test strips that had expired. If E-6 is found, the test strip was contaminated by blood or solution before the instrument was made.
An electronic error or the reuse of a test strip is indicated by the code E-7. E-8 indicates that the temperature is too high for a good test, and E-9 calls for a new battery. According to Accu-chek, E10 is flashed when date and time settings can be off.
Instead of a numbered code, “Err” is displayed on some Aviva models. The icons connected to the problems mentioned above are used by these devices to signal the error. According to Accu-chek, the only exception is EEE, which denotes an electronic fault.
