EM720 Power Quality and Revenue Meter
Configuring Recorders
The EM720 is provided with an 8-MByte or 16-MByte flash
memory for data, event and waveform recording.
The meter memory is fully configurable except of the files
that keep monthly and daily billing profiles and energy load
profile. They are pre-configured at the factory and may not
be changed by the user.
Two of the data log files are automatically configured in your
meter for recording EN51060 compliance statistics data and
harmonics survey data. You cannot change the file records
structure, but you can still change the amount of memory
allocated for these files.
The remaining memory can be freely partitioned. If you wish
to change the factory settings, follow the guidelines in the
next section.
Configuring Meter Memory
To view the present memory settings, select Memory/Log
from the Meter Setup menu, and then click on the Log
Memory tab.
The following table describes file options.
