The memory size allocated to the file. Set automatically depending
on the size of the records and the number of records in the file.
The numbers of sections in a multi-section TOU profile data log
file, or the number of recording channels in a waveform log file
Allocates the file memory for predefined number of records
The size of the file record for a single channel or a section. Set
automatically depending on the file and on the number of
parameters in the data record
The number of parameters in a single data record (not including
the EN50160 statistics files)
Memory is allocated for each file statically when you set up
your files and will not change unless you re-organize the files.
The meter automatically performs de-fragmentation of the
memory each time you re-organize your files. This helps keep
all free memory in one continuous block and thus prevents
possible leakage of memory caused by fragmentation.
To change the file properties or to allocate the memory for a
new file, double click on the file partition you want to change,
select desired parameters for your log, and click OK. For your
reference, the record size and the number of records available
for your file are reported in the dialog box.
To delete an existing file partition, click on Delete and then
click OK.
The following table shows how to calculate a file size for
different log files.
