memory
For each measurement, your blood glucose value is automatically saved with the date and time unless
“CONTROL” was activated for a blood glucose measurement using control solution.
The memory can store a maximum of 900 measured values. If the memory is full, the oldest value is
replaced by the most recent value. You can call up every individual measured blood glucose value.
You can also calculate and display the average blood glucose value for the last 7, 14, 30 and 90 days.
