Memory demand for one record:
Number of bytes = 8 + 4 * number of measured values
The duration of data recording until the data memory is filled
can be calculated by the following formula:

d = duration of data recording in days
n = number of values to be stored (without date and time)
M = averaging interval in seconds
Example:
Storage of eight measured values per minute.
Number of Bytes = 8 + (4 * 8) = 40 bytes per record
Memory demand per day = 24 * 60 * 40 = 57600 Bytes
At 7 MBytes internal flash 7 * 1024² * 60 / (40 * 86400) = 127,4
days can be recorded.
