EM720 Power Quality and Revenue Meter
The following table can help you calculate an estimated
file size for conventional log files when planning your
memory allocation. The actual file size will normally be a
bit bigger.

The meter memory is pre-configured at the factory for
common data trending, billing, power quality and fault
recording applications as shown in the following table.

NOTE
The meter automatically performs de-fragmentation of the
memory each time you re-organize your files. This
prevents possible
fragmentation. Depending on the data stored in the
memory, it may take from seconds to a couple of minutes.
