Error codes ---
Averages cannot be calculated.
This may be because:
- you have not set the time and date,
- only test results without a time and date are saved,
- only test results that are not included in the calculation are saved, e.g. control results,
- no test results were saved in the period in question, e.g. all test results in memory are more than 7 days old,
- the chronological order of the test results in the memory has been interrupted.
