Note 1. The standard 8Mb capacity represents more than 3 years of data storage, at one reading (of 3 gauges) every 10 minutes.
For virtually all practical applications, there will be substantial memory capacity left unused at the end of the deployment, as the
memory usage life will typically exceed the life of the internal battery pack.
