Formula to Calculate Logger Storage Capacity
Please use the formula below to calculate the maximum period that you can allow to
pass before you have to download your logger. Failure to download data within this
period will lead to a partial loss of data, since the logger's memory will start to
overwrite the data. The length of that period is determined by a constant (86), the
sampling interval in minutes (which can be altered) and the number of sensors
installed (variable).
No. of Days until = 86 x Sampling Interval (min.)
memory wraps Number of Sensors
Example:
16 sensors logging every 2 hours:
86 x 120 = 645 days
16
12 sensors logging every 1 hours:
86 x 60 = 430 days
12
5 sensors logging every 10 minutes:
86 x 10 = 172 days
5
32 sensors logging every 10 minutes: 86 x 10
= 26 days & 21 hours
